The White House

Posts Tagged ‘Basic’

The dining room adds an enjoyable social dimension to the consumption of food. It can bring a family together at mealtimes as well as enabling people to host gatherings for friends and colleagues. Dining areas are common features of a kitchen or living room, but a separate room set aside for eating can increase the level of intimacy and relaxation.

Ideally, the decor of a dining room should be soothing and unobtrusive. Bright colours may detract from one’s culinary skills and prove distracting. Instead use plain, deep colours to help create an intimate, warm atmosphere. Furnishings should compliment the dining room rather than divert attention so spectacular, over-elaborate paintings or pictures may not be the ideal kind of decor.

Lighting is one of most important features of a dining room playing an important role in creating the right sort of atmosphere. Dimmer lights can be used very effectively to maintaining the correct ambience and are easily adjustable, according to mood and purpose. Candles are also worth considering and can help to create the relaxing kind of lighting so important to a dinner engagement.

The table is central to a dining room. Round tables are good for informal gatherings and can cater for a number of guests. However, they don’t usually have the space for serving dishes and other dining accessories during a meal, which means excessive clutter during dining. Rectangular tables are more suited for this purpose and are able to house larger gatherings of four to eight people, as well as providing space for extra dishes and plates. Oval tables with extendable leaves provide a space-effective alternative, able to cater for even more guests. In addition, they are easily stored during non-dining periods.

Dining chairs usually come as part of a dining set and are designed in proportion to the table. If you chose to buy separately close attention should be payed to the chair’s dimensions – seating height is of course very important. It would be also be a good idea to include cushions for dining chairs to ensure the utmost comfort for the occupants. Popular versions come with attachable bows that can be tied to the chair frame.

Mealtimes come with a large collection of accessories such as serving dishes and plates. A table can fill up quickly with these items so adequate storage space is important. Sideboards can prove attractive enhancements to a dining room. Although the scale of these furniture pieces should be carefully considered over-sized sideboards can have an imposing effect on a dining area. Hostess trolleys offer another alternative and can be easily moved around the room. They’re also useful at keeping plates and dishes warm.

Whatever kind of decor you choose, remember that your dining experience should be relaxing and pleasurable. Some of the ideas mentioned above should help you realise your dining room’s full potential.

Efficiency in comparison to traditional soil growing systems would be one of the major advantages. Commercial production and just plain hobbyists would find that moving from regular soil growing methods to the modern Indoor Hydroponic systems to be more beneficial. Freedom from uncontrollable variables such as the weather, climate and time of day would be the most important factor over traditional growing methods. Farmers in Middle East countries would be able to grow plants such as vegetables only previously grown in tropical countries. Light and amount of growth nutrients to be absorbed by the plants could be optimized for best results without wasting any resources. Plant care could be individualized as to the amount of nutrients and light they receive at any time of the day. Plants grown in pots or plots tend to reach a growth plateau, wherein they become root bound and transplanting them is the best solution. This may present the individual with a sense of frustration and could be messy. Expert advice and appropriate planning beforehand could eliminate such unwarranted difficulties experienced with soil based planting.

 

Expenses made at the start of the project can be offset by the advantages in the long run. Fertilizers with their ever rocketing cost are major source of expenses in plant cultivation. Plants only take the nutrients they can absorb so maximum nutrient absorption without the risk of putting too much fertilizers is eliminated. But the risk of putting too much nutrients which leads to root damage remains, so proper nutrient feeding is advised.

 

All in all, the hydroponic system of growing plants increases plant production and quality of the crops. Nutrients essential for plant growth are readily available, proper ratio and distribution is assured resulting to better efficiency. Pesticides and plant diseases can be avoided as no soil is needed. Soil is an ideal medium for infection and disease, so harm to both plant and the individuals are reduced. Expenses are also reduced as pesticides are eliminated so overall; cost effectiveness is enhanced and make hydroponics a more economical way of growing plants.

 

For the environmentalist, the hydroponic system of growing plants also presents a more desirable and alternative way of plant production. The effects of growing plants through this new system has proven to be less polluting as it totally removes the need for pesticides and leaves the soil free from contaminants. Scientifically tests also show that plants grown through the hydroponic system contain more vitamins and minerals compared to those grown through fields.

 

Productivity is also increased with the use of Indoor hydroponic systems. Limited spaces for plant cultivation are maximized because smaller pots are used. Indoor hydroponic systems utilize different types of automated watering systems like drip, pumps and other means, allowing for a low maintenance operation. Spaces not available for plant growing can be utilized and together with regular soil gardens or fields, maximize each growing season.

 

 

Types of Indoor Hydroponic Systems

 

Wick or NFT

The system most often used, operated and maintained with the outmost ease. It requires very little setup and maintenance. This is done by simply cutting a hole in the bottom of the pot and a wick is inserted. The wick’s other end connects to the water reservoir below the pot.

 

Reservoir or Ebb and Flow System

A growing medium is directly placed into a pan filled with water and nutrients. It is easy to maintain, the pans contents needs only to be replaced every few days in order to maintain an effective system. Root adsorption is maximized with root surface in contact with the water, oxygen and nutrients are readily absorbed.

 

Drip Systems

The most common of all systems, drip systems are the most likely choice of hobbyists and professionals alike. The nutrient solution is kept in a container below the plants and is distributed by a pump to each plant thru a drip irrigation system. One type would be the Recovery type system; excess nutrients are recycled and channeled back into the reservoir. Another would be the Non-recovery type where excess system is not funneled back into the system, one advantage of this is that is a low maintenance system. Ph and nutrient concentration remains stable but is not as economical as the recovery type system.

 

Aeroponic System

Technically, the aeroponic system is the most advance of the three. Plants are suspended either without a growth rock or growing mediums. This permits the plant to breathe more air through the roots. Nutrients and water are introduced by timed misting. Root health is maintained by a timer and is set at intervals of a few minutes.

 

Improper use of fertilizers is the common cause of many plant problems. Inadequate amounts cause weak and under nourished plants while an amount above desired quantities may burn and even kill the plant. Good judgment and decisions are required when a plant grows. Below are guidelines for applying nutrient solutions.

 

Hydroponic nutrient solutions are normally sold in concentrated forms. They are then added to the water supply with a specific ratio. Ideally, 150-600 parts per million consists a normal concentration of hydroponic solution. Normally sold in two or three parts because direct combination is not possible. Remember to mix nutrients into water first before combining, never combine two nutrients together.

 How Much Hydroponic Nutrient Solution?

 There are specific proportions for each plant type and phase of its growth. Advances in nutrient solutions have greatly improved the precision of concentration based on a plants growth stage. Hydroponic nutrient solutions are usually sold in “grow” or “growth” formulas for the vegetative phases and “bloom” or “flower” for the flowering phase of the growth cycle. Remember to switch to the bloom formula during the bloom stager to increase yields exponentially and max out your plants capacity.

In poor growing conditions weak nutrients are recommended. Low lighting, overheated gardens, crowding and root bound plants. Weak nutrients are also ideal for newly rooted cuttings and for transporting plants or when they are in the transition of growth cycles.

Normal, healthy plants can be used with regular strength solutions in ideal growing conditions. Increasing nutrient solutions could be utilized to enhance efficiency of your gardens. An ideal system such as high quality lights, proper aeration and ventilation when present is the only instance wherein you could increase the level of nutrient solutions to improve plant growth. Gradually increasing the nutrient solution is advised as not to burn the plant roots.

 

Various additives are also available for optimum plant growth. Maintain good grow logs or records of types of additives used, when applied and results. This enables you to measure its effectiveness in the future. If there are any negative effects with experimentation, flush or rinse your hydroponic system immediately.

 How to measure Hydroponic Nutrient Solutions

 Electronic conductivity of dissolved minerals in the water is the usual basis for determining nutrient solution. Parts per million (ppm) is the unit of measure. But this is just a general way of measuring conductivity in the solution and not the actual strength of individual minerals. This is the main reason why hydroponic nutrient solutions are sold as a mix of 3 parts. Once the desired mix is achieved it is very convenient to change the concentration to achieve proper conductivity.

Overuse of Hydroponic Fertilizers

 Flushing out your growing medium is the first intervention once any signs of over fertilization are observed this is to prevent further damage to the plant. Clean water is used for flushing until signs of nutrient deficiency are observed in the plant. Normal feeding and schedule is then resumed. Some hydroponic systems require a top down flushing to completely clean out the plant.

 

2 weeks before your expected date of harvest, flushing is recommended for the plant. It is done to leave your harvest free from the hydroponic nutrients solution taste. 

Complete freedom from environmental factors gives indoor hydroponic gardening its ultimate advantage. All the elements needed for optimum plant growth are provided by the indoor hydroponic gardening system. Light, temperature, pH, CO2 and Oxygen are important factors that should be considered in planning your indoor hydroponic garden system.

 Light and Photosynthesis

 Essential sugars are created by plants through photosynthesis which is the process of converting carbon dioxide, water and nutrients into energy. Light is considered the most important factor because it provides energy for this chemical reaction. Studies show that an increase in light intensity directly increases the amount of sugar produced. This steadily goes up till the saturation point for light is reached by the plant. Increasing the level of light received by the plant should also be considered. Normally, a plant receives around 8-12 hours of sunlight in a day depending on the season. Plant exposure to this amount of light received in a day should be maintained in an indoor hydroponic garden system. Spacing is also important, be sure that they don’t block the light and ensure all plants received equal amount of light.

]]>

Plants not receiving enough grow light will have lasting negative effects on its growth even when corrected. Some characteristics are stems which are spindly and elongated leaving them ineffective in supporting plant growth. A decrease in the amount and size of the leaves is also one problem. More damaging effects of improper lighting are a decrease or absence of fruits, decreased overall quality and a change into a yellowish pigmentation for the plant.

Carbon Dioxide also plays a major role in Photosynthesis. Plants utilize the CO2 present in the atmosphere than anything else. CO2 systems are available which increase the levels of CO2 in your indoor hydroponic garden system

Good ventilation should also be considered as they maintain temperature and a steady fresh supply of CO2 and oxygen at all times. Complex setups require more complicated ventilation systems but an oscillating fan set on the same timer as the lights would ensure airflow that eventually allows for optimal plant nutrients in an hydroponic system.

Ebb and Flow hydroponic systems or reservoir systems are one of the easiest to build and maintain. Simplicity and low cost in setting up make it ideal for home hobbyists. Basic setup consists of a growing tray for plants in containers. Usually used with pebbles, perlite and rockwool gardening mediums. Reservoirs filled with water and hydroponic nutrient solutions are placed under the growing medium. A timer controls the amount of water pumped back into the growing tray. The draining action helps provide a steady flow of oxygen to the plants roots. An overflow drain is installed to regulate water height and avoid overflow.

 

 

Building Ebb and Flow Hydroponic System

 

 

 

The following hydroponic supplies are required for an Ebb and Flow hydroponic system

 

 

 

Growing Tray

 

 

 

Root protection requires a growing light that shields your roots from light. Plastics are preferred to metals and wood due to its light weight and durability. A thorough check of the growing medium is required to make sure that water drainage is complete. Root rot, pests problems and molds are the main problems encountered by improper drainage.

 

Plant Pots

Any non-metallic plant pot with drainage holes will suffice for a simple ebb and flow system.

 

 

Growing Medium

 

Ebb and flow systems need no special type of growing medium. Clay pebbles (sometimes called grow rocks) are usually used, they don’t need to be mixed with other mediums. Due to frequent flooding cycles, it is advised that water retention be avoided.

Supports

Support for the tray suspended above the reservoir is needed. The setup of the indoor system would dictate if a simple table or milk tray, or a customized support is required. Something sturdy is what you need for supporting the full weight of your setup. Always include the weight of the water and nutrients in planning. Taking note the mature size and weight of the plants should also be considered. Changing the supports would present an impossible if not very difficult scenario once the plants reach their full growth size.

 

 

Reservoir

 

Any large plastic can be used as a reservoir (rubber tubs and trash cans are also ideal). Rust is the main problem with metal containers.

 

 

Drains

 

Two drains are required for your garden, a drain for the water to return to the reservoir and one for the overflow drain. Fill pipes also serve as a drain pipe, allowing it to run up the same way it came down. Overflow pipes should be designed at the desired maximum level of water for the indoor hydroponic garden system. Be sure that the overflow pipe is large enough to accommodate the amount of water to be pumped out of your grow space. Ideally a figure of 125% to 135% of the amount is desired. This assures a optimum flow of nutrients for the growing medium and avoids salt and mineral to buildup.

 

 

Water Pump

 

Pump size depends on the indoor hydroponic systems needs. The amount of water and distance are factors to be considered for the size of the pumps. Aquarium pumps can be used for most small scale systems.

 

 

Timers

 

The type and cost of timers depends on the specific setup of your gardens need. Hobbyists usually employing a single time schedule can work with a cheap timer readily available at a Home Depot or Lowe’s type store. Larger more sophisticated timers are needed for advance or large scale ebb and flow systems this allows control for more than one section at a time.

 

 

Flexible Plastic Tubing

 

Transparent flexible tubing’s should be avoided to prevent algae build up. Ordinary flexible tubing’s may also be used. 

 

 

Care of Ebb and Flow Hydroponic Systems or reservoir systems are one of the easiest to build and maintain. Simplicity and low cost in setting up make it ideal for home hobbyists. Basic setup consists of a growing tray for plants in containers. Usually used with pebbles, perlite and rockwool gardening mediums. Reservoirs filled with water and hydroponic nutrient solutions are placed under the growing medium. A timer controls the amount of water pumped back into the growing tray. The draining action helps provide a steady flow of oxygen to the plants roots. An overflow drain is installed to regulate water height and avoid overflow.

 

A great indoor garden requires a good grow light. It could mean the difference between success and failure. Having the right hydroponic light is the single-most important and costly decision in setting up your garden.

 Hydroponic grow lights come in three main types:

 

Incandescent lights

These are the usual lights found in homes. They are generally a poor choice for garden grown lights because of their limited light spectrum and inefficiency.

HID (High Intensity Discharge) grow lights

Producing more light (up to 10x more lumens/watt than an incandescent light),are more efficient. Drawbacks would be, they produce more heat, generally more expensive than incandescent lights and requires the additional expense and maintenance with ballast. It takes around 100 hours before hydroponic HID grow lights reach their optimum working conditions, or until they reach light intensity and color stability. 

Natural Sunlight

Expense for acquiring artificial lights can be skipped by using sunlight. This is done with the use of solar room, greenhouse or large windows which allows plenty of sunlight. Or you can do this outdoors; hydroponics does not necessarily mean the cultivation of plants indoors but it growing plants without the use of soil.

Basic setup for an indoor garden is 1000w of lighting for and area of 16-25 square feet of plant area. Reflectors and/or light movers should also be considered as they improve efficiency of the indoor hydroponic gardening system. Ballast may also be needed as numerous hydroponic grow lighting require igniting.

 Some Basic Facts

Before plugging in your grow light

Different plants require different levels or types of lighting, this paragraph would deal on some simple know-how on how to make an effective lighting setup. In setting up your garden, it is essential that you determine your growing area in order to determine the best lighting setup for you. Light is an essential factor in the growth of plants, it is important that the lighting solution you chose for your garden is adequate for its size. A poor or ill advised decision would certainly reflect on the quality of plants you produced. Inappropriate budgeting like cost cutting specially on lighting would just prove to be uneconomical and inefficient in the long run.

A general rule for lighting that area coverage is determined by a light wattage output. Reflectors might be used to increase the light area and reach corners but effectiveness is still determined by this formula.

Day and Night Cycles

The type of plant and its stage of growth generally determine the amount of light needed. A common cycle is that with 18 hours of light and 6 hours of darkness which is recommended for its vegetative growth phase.

For seedlings, a continuous light source is needed until the first real leaves appear. When the leaves appear, the regular 18/6 light cycle is used. Fluorescent or incandescent lights are best for seedling because of the low heat and soft light they generate. Automated timers maybe used to ensure consistent light cycles. Inexpensive timers are also available; this can be found any hardware or Home Depot/ Lowe’s type store.

Light and Photosynthesis

The plants exposure to light intensity, duration and light color directly affects the amount of energy needed for photosynthesis. The color of the light, Blue simulates the summer sun, Orange for autumn seem to stimulate photosynthesis best. The light spectrum produced by metal halide bulbs (Blue lights) and high pressure sodium bulbs (red/ orange lights) produce this effects. HID grow lights produce these effects owing to their popularity to hobbyist and professionals. Combination of metal halide and high pressure sodium bulbs provides the complete spectrum of light produced by the sun.

Use Caution When Working with Lights

The combination of water, electricity and chemicals in such a closed-in space makes the grow room one of the most dangerous places in your house. Keep in mind to separate your ballast by elevating it from the water-containing areas of your hydroponic growing system. 

These are the materials that mimic the soil in everyday gardens. It serves as a support system for your hydroponic indoor garden. They function mainly for anchoring the roots and a reservoir for water and nutrient solutions. Special attention is also placed on aeration or proper plant respiration and drainage. A balance must be kept between keeping the plant nourished and over saturating the roots.

 Types of Growing Mediums

 Choice of a specific growing medium mainly depends on the type of growing system to be used. Certain systems have no mediums used because plant growth is best when roots are suspended in air or water. Improvement made with newer growing medium mixtures has been introduced for optimum plant growth in certain systems. Ideally, an equal mixture of water and air is advised making it available for the roots to utilize at all times. Water by gravity always moves downward through coarse mediums only to be deposited in the bottom of the container. This is eliminated with the use of a hydroponic system as water is constantly circulated in the system. The only system that this would not work would be the Ebb and Flow Systems.

 Clay Pebbles

Recyclables, it can be constantly reused indefinitely reducing upkeep costs for your indoor garden. Size of the pot is one limiting factor as they do not possess good nutrient lifting ability, but effectiveness is enhanced in smaller pots and containers. Another advantage would be their neutral pH and they don’t retain nutrients. Ventilation and aeration are also maximized because of the spaces created between pebbles.

 

Clay pebbles are usually used together with net pots in drain and flood indoor hydroponic gardening systems. Water flow in roots is enhanced by their natural shapes and spaces hey create between them, therefore maximizing the absorption of nutrients. When using the Drip irrigation hydroponic system, use absorbent mediums to provide better retention and nutrient circulation.

 Coconut Fiber

Shredded husks of coconuts as a growing medium has also been growing in popularity. Packaged in a variety of ways like blocks, pellets, cubes and shredded fiber it can be a good substitute for any type of growing medium. It is also commonly mixed with other growing media such as perlite or rockwool.

 Why Use Coconut Fiber as a Growing Medium?

 Coconut fiber is actually a waste product; its ability to be used for other useful means takes a great step towards recycling and environmental awareness. It is the first totally organic medium which could be utilized for indoor hydroponic gardening. It is superior to rockwool in water handling ability and oxygen capacity. Coconut fibers also possess root stimulating hormones and prevent root disease and fungus infection. In its natural state, coconut fibers provide a good and rich medium for the coconut when it lands in the ground.      

Special attention should be given as to the quality of the coconut fiber to be purchased. Low grade quality is not well suited for gardening as they contain high sea salt content and fine grain texture. 

Perlite

Originally used as an additive to aide aeration and improve soil drainage, it has become one of the popular hydroponic growing mediums. Commonly used with a 50/50 mix with vermiculite, it is derived from volcanic glass with holes throughout produced by exposing it to high temperatures created by water bubbles.

 Advantages of Growing with Perlite

 Inexpensive and readily available is one of the causes of its popularity. Used in wick type hydroponic systems because of its aerate nature thereby giving a good wicking action.

 Disadvantages of Growing with Perlite

 Health hazards come with the use of perlite when inhaled, a mask is suggested when working with perlite as a growing medium. A high degree of care and maintenance is also required. Water retention is one of its weakness therefore constant watering is required.

 Vermiculite

Used in conjunction with another growing medium compliments the qualities of the other. A popular and common mix is that with perlite. In a 50/50 mix vermiculites property which is water retention (200 – 300% of its weight in water) complements perlites very porous quality and a balance is achieved.

 Dangers of Using Vermiculite

 Vermiculite can be a health hazard if not handled properly. Due to its nature of containing small amounts of asbestos, it can be very dangerous when inhaled. It easily dries on an individuals fingers when touched even when wet. It is not also practical to reuse because of the rinsing and drying required. Water retention is also a problem, because of its high water retention if not used in pair with another growing medium, root damage is likely and plant death are the result.

 Rockwool

Rockwool specifically made for indoor hydroponic gardening systems. It has remained as one of the popular growing mediums. Transplanting plants when grow too big from their previous containers is also eliminated. When this happens the existing cube with the plant is merely placed on top of a larger cube and the roots would grow through both cubes. Water retention qualities of rockwool is 10 times greater that of water. Its porous nature makes it virtually impossible to over water. Recyclable, it can be used for the next crop by merely rinsing, making it economical and environment friendly.

 Disadvantages of rockwool

 A natural pH found in rockwool is one of its disadvantages, pre-treatment is required before it is used as a growing medium. Methods of lowering its alkaline content includes mixing it with a solution of pH down, trace mineral solutions and a 24 hour fish emulsion and is then rinsed thoroughly. Gloves should be used when handling rockwool because of skin irritation but is not when rockwool is wet.

Fluorescent Grow Light

 Inexpensive and readily available in hardware stores and be utilized with regular light sockets. Producing less heat or none at all compared to full-size fluorescent grow lights.

Not just because of its small size and low heat output; compact fluorescent lights also produce the widest range of color spectrums to any type of lighting. It is ideal for shelf gardening due to their low heat output making the use of multiple shelves on top of each other possible. Compact fluorescent lights can be used with seedlings and small plants in a well designed hydroponic system indoor garden.

 Common Problems with Compact Fluorescent Light Bulbs

 Problems with compact fluorescent light bulbs like inefficiency and poor light penetration are common.  Several compact fluorescent bulbs maybe used and consume energy as that of one HPS bulb, but do not produce the same useable light for the hydroponic indoor garden. 

Optimizing Fluorescent Grow Lights

 With the disadvantages of comparative inefficiency compared to HID lights, several things maybe done to counteract this.

Properly matching lights to the corresponding growth cycle.

Increasing Watt ratings increases light penetration

One cheap and easy way to maximize energy consumption is by the use of reflectors. Compact fluorescent lights have a 360 degree of distribution but only 90 degrees of it can be practically used. Reflectors direct the light to corners in order to maximize the light produced.

 High Intensity Discharge Lighting

 HID light bulbs are the most after lighting system by both hobbyist and professional growers. It has made possible all-year, all-season planting for thousands of indoor gardeners and industrial nursery growers. Due to their efficiency ( 10x more light produced than conventional incandescent bulbs) and color spectrums ideal for plants have resulted to better yields and plant quality all year round. Metal Halide (MH) light bulbs mainly produce blue lights, making them ideal for plants undergoing the vegetative phase of development.

Industrial cultivators the world over are the main users of HID grow lights. HID lamps provide numerous advantages that conventional Fluorescent and incandescent lights lack. Monetary benefits abound, it boosts overall plant production giving better harvests, and environmental factors are eliminated allowing all year-round production. HID lights operate stock 110 to 220 volts AC home currents and have a standard three prong adapter to link up. HID grow lights mostly come with a ballast resistor and reflective hood.

Photosynshesis in plants allows plants them to produce their own energy. Chlorophyll in plants enables plants to convert CO2, water and energy from light to nutrients and sugars. When all this elements like CO2 and nutrients are readily and plenty in a desired surrounding, the potential for growth is bound only to the amount and quality of light available.

 High Pressure Sodium (HPS) light bulbs produce reddish light, it is ideal during the fruit phase of the plant cycle. Cooler (blue) and Warmer (orange) color spectrums raise chlorophyll production and fruit energy. The sun produces cooler lights when it is higher in the skyline, seen in the summer calendar months. It is essential for plant growth shape and keep it tight. Warmer light, experienced when the sun is lower in relative position to the skyline is important for blooming plants and during the fruit phase.

Choice of lights can also depend on the type of plants grown. Metal Halide growth lights are ideal for bushy harvests such as cabbage and vegetating herbaceous plants. Blossoming plants on the other hand is better suited by high pressure sodium growth lights. Conversion light bulbs are also available for different organizations. More expensive than other lights, conversion lamps give that extra advantage of starting your plants with a metal halide growth light giving taut, small development and being replaced by high pressure sodium light bulbs when the fruit stage of the plant is reached. Recent developments have introduced convertible ballast resistors for regular metal halide growth lights and high pressure sodium light bulbs.

HID grow lights main advantage is that it eliminates such factors as climate, temperature and time of day. Season dependent plants can be grown throughout the year; they provide an alternative to solar light. For those who are garden and flower hobbyists, this would be a plus.

Hydroponic growth lights also gives you control over light exposure. Allowing us to hasten a plants growth or that flower to bloom. Ideal light color, duration and concentration are the key factors in growing those choice plants.

 High Pressure Sodium Bulbs 

A clear ceramic arc tube suspended inside a glass bulb characterizes High Pressure Sodium Bulbs. Xenon gas is the main component inside the inner tube which is then ignited to produce an arc of light. Sizes range fro 35 watts up to 1000 watts. The most popular of which are the 250 watts, 400 watts and 1000 watts.

 Advantages of High Pressure Sodium Bulbs

 Efficiency is one of its advantages; they provide the best light penetration and have strong light spectrums necessary for plant growth. Mainly producing red and yellow lights or little or no blue lights, they mimic the autumn sun. Popularity for HPS lights are mainly attributed to their low energy to light ratio and is the most economical and efficient than any other type of lighting system. HPS lights work best during the flowering or fruit stage of the plant growth cycle.

 Disadvantages of HPS High Pressure Sodium Bulbs

 High Pressure Sodium Bulbs produce great amounts of heat. Proper ventilation and good garden construction and planning help to offset this negative effect. Like all HID growth light systems price is the main drawback compared to fluorescent lights. HPS lights are currently more cost effective compared to other HID growth light systems.

High Pressure Sodium Light bulbs are replaced after 24 months to ensure their and your gardens efficiency.

 Metal Halide Bulbs

 Metal Halide bulbs are constructed by placing an inner arc tube inside vacuum-sealed glass tubing. Electric currents passed through the inner arc which in turn ignites mercury and iodide materials in the tube.

 Advantages of Metal Halide Bulbs

 Metal Halide Bulbs mimic sunlight during summertime. Producing a blue spectrum of light most ideal for plants in their vegetative growth phase. They are also a good choice for indoor hydroponic garden systems because of their efficiency in producing light.

 Other Metal Halide Bulb Information

 Available from 70 to 1500 watts, Metal Halide bulbs present a wide variety of choices. Most popular and commonly used are the 250, 400 and 1000 watts metal halide bulbs. Ballast specifically tailored for each bulb is also essential. Mounting positions depend on its specific bulb type (marks or guides are usually provided). HOR bulbs are mounted horizontally, BU/BD is vertically mounted and U (universal) bulbs could be mounted either way. The vertical position is the most ideal and provides utmost efficiency.

 

Carbon Dioxide (CO2) Systems

Carbon Dioxide (CO2) as described in the previous paragraphs is one of the most important elements needed for plant growth. CO2 is combined with nutrients, water and energy from light (grow lights/ sunlight) is utilized during photosynthesis producing essential sugars that provide energy for the plant. Any factor missing needed for photosynthesis will limit the plants growth potential. In order for a plant to grow to its utmost potential and for it to yield the best results all of the elements must be present. 

Carbon Dioxide (CO2) Injectors

One of the most cost effective way of adding CO2 to an indoor hydroponic garden system is with the use of CO2 injectors. A valve, regulator and gauge are used to measure CO2 levels injected to the air. Sophisticated CO2 injectors are also used to control CO2 release. CO2 tanks are readily available from medical supply outlets and restaurant supply stores.

Carbon Dioxide (CO2) Generators

Investing in CO2 generators would also be wise for long time use in your indoor hydroponic garden systems for several crops. CO2 generators burn propane, natural gas or other carbon based fuels to produce carbon dioxide. More expensive than CO2 tanks, they provide a more convenient way of producing CO2. Long period and continuous use of CO2 generators has proven to be more efficient and economical than purchasing injectors and many tanks.

Carbon Dioxide (CO2) Monitors and Controllers

CO2 monitors with controllers automatically maintain indoor hydroponic garden systems CO2 levels. It is advised for large-scale gardeners or hobbyists and enthusiasts with that extra cash to invest. Often in the hundreds of dollars, they are quite expensive but are really effective if you can afford it. An electronic CO2 monitor together with a CO2 controller are used to maintain CO2 levels. Monitors could be sold separately and can be used with various types of controllers giving room for flexible indoor hydroponic garden designs. 

Water

Water quantity requirements vary according to the type of indoor hydroponic garden system. Adequate levels of water should be maintained whatever type of indoor hydroponic garden system used. Water deficiency even if reversed and corrected cause permanent loss in production.

Not only the amount of water but also quality of water is important. Poor quality also causes serious problems for any indoor hydroponic garden system. The use of tap water can affect the nutrient balance in hydroponic nutrients solutions. Tap water naturally contains mineral and salts. Often referred to as “hard water,” tap water is offset by constant monitoring and adjusting nutrient solution. Salt content should always be kept below 325 ppm (parts per million) whenever possible.

Temperature

 

Temperature is a gauge for optimum production for every plant. When plants are exposed to extreme ranges of temperature, stunted growth and poor fruit yields are the result. Plants have specific temperature ranges for their ideal growth. Warm-season vegetables and most types of flowers have 18o C and 260 C as an ideal temperature range. Cooler season vegetables like lettuces have a 10o C to 18o C range.

Ten basic rules for gardening 

Rule #1 – Buy plants from a very reputable source–I prefer nurseries over discount stores and warehouse stores. 

Rule #2 – Select plants that will grow in your climate–consider your high and low temperatures. 

Rule #3 – Plant your plants in the right place in your yard–sun-loving plants in the sun, shade-loving plants in the shade. 

Rule #4 – Provide your plants with complete nutrition. Most fertilizers and plant foods don’t. Spray-N-Grow and Bill’s Perfect Fertilizer provide major and minor elements identified by botanists as necessary for plant growth and production. 

Rule #5 – Water your plants properly. 

Rule #6 – Keep your plants bug free. Look for bugs on your plants as often as possible. Apply an organic and environmentally friendly bug killer if necessary. 

Rule #7 – Watch for plant disease. Spray your plants with Physan 20 or Serenade if you see any wilting, black spots, etc. 

Rule #8 – Weed around your plants or use All Down Organic Weed and Grass Kill or Burnout Weed and Grass Killer. 

Rule #9 – Deer, rabbits, squirrels and other animals may try to feast on your plants. If you see evidence of munching, use a humane animal repellants. It may take a little detective work to figure out what type of hungry animal is invading your garden.
