Ein Gedi system

First developed in Ein Gedi Israel, hence the name, the Ein Gedi System (EGS) introduced a revolutionary new method to hydroponics. The system is comprised of fully enclosed rectangular growth chambers, inside of which, nutrient solution is circulated 1-6 inches below evenly spaced mesh baskets that contain the plants. The air gap between the baskets and solution is misted by sprayers residing along the upper inside of the chamber. Roots growing into the mist zone are subjected to intense...

Growers guide to popular plants

The following table outlines the favorite conditions for these plants to thrive in your hydroponic garden. Adhere closely to these parameters and you will be happily surprised by the results. Always use a high quality hydroponic nutrient and maintain a healthy growing area by allowing plenty of light, air and moisture to reach your plants. Seed packets will contain more information on the particular strain you wish to grow.

Making clones of your favorite plant

A second method of starting and restocking your garden is cloning. In this procedure, a small growing tip is taken from a mature healthy plant and made to grow its own roots. This method is independent of the plants reproductive system and thus eliminates the possibility that future generations will continue to evolve, as cloning results in plants which are exactly alike in all aspects. Cloning is very popular with indoor growers - and sheep > ) - that wish to preserve the characteristics of...

If you are totally new to hydroponics and gardening, take a few months getting your green thumb cause once you go commercial, you will be counted upon to deliver quality produce on time. Another important factor in your success is product...

Its all about the roots

Root systems vary in size from those of a seedling, perhaps a few inches long, to those of a 300' redwood (pictured at right holding up the author) which can grow larger in size than the visible tree itself Regardless of physical size, roots serve the plant three essential functions the uptake of water and nutrients, storage for manufactured materials and providing physical support for the plant above ground. Hydroponics is all about the roots - healthy roots The absorption of water and...

Problems with your plants

Just as your garden faces infiltration by bugs, so it does from disease. However, the wonderful thing about soilfree garedening is that there is no soil to harbor disease. Instead, you have only to contend with the nutrient solution. To avoid the growth of algae and disease causing organisms that may propagate within your nutrient tank, there are a few precautions you can take to avoid this scenario. First off, keep you nutrient temperature below 80 degrees F. Better yet would be to keep it...

Soilfree hydroponic mediums

In most hydroponic gardens, soilfree mediums are used primarily for starting seeds and when rooting cuttings. The less medium a system requires, the easier and less expensive it is to operate. This is a major consideration for those who wish to make a profit from their hydroponic gardens. Modern day soilfree mediums have come a long way since the use of river gravel and sand. A perfect medium is one that is able to hold a nearly equal concentration of air and water. As you have leaned, your...

Stages of growth

A plant's life cycle begins with germination, recognized by the above-ground appearance of a growing shoot. Mated to this shoot are two small, round leaves known as cotyledons (A). Once these leaves begin manufacturing food, the plant begins to grow and enters the seedling stage. During this time the plant develops it first set of true leaves, resembling those of a mature plant. The primary formation of a root system begins. The root development that takes place at this time is key to the rate...

Stocking your hydroponic garden

Once your seedlings or clones have established a root system and hardened off, they can be transplanted into your system. If you used rockwool as a starting medium, this process involves nothing more than placing them into your system and turning it on. If you used a loose starting medium like perlite or cocopeat, you will need to gently remove the medium from the young roots by either rinsing or soaking them in a pail of warm water OR use a porous open-weave mesh to keep the cocopeat from...

The First Step To A Great Garden Is Planning

Consider the space you have available for your intended garden. Don't forget that if you plan to grow indoors in a tight space you will also need room to access your garden and perform routine maintenance such as pruning and nutrient changes. For this purpose, leave yourself ample space to work. Too many people try to fit too much garden into too small a space. Remember - a hydroponic garden will give you a significantly higher yield than a soil garden of equal size. If you plan to grow...

The nutrient film technique

Work on the Nutrient Film Technique, or NFT for short, was pioneered by Allen Cooper at the Glasshouse Crops Research Institute in Littlehampton, England. Plants are placed atop an inverted 'V' shaped channel, sealed on all sides, through which a thin film of nutrient solution passes along the bottom. Roots grow down along the channel, receiving oxygen directly from the inside of the trough, while receiving water and nutrients from the thin film of nutrient below. The enclosed chamber maintains...

Water the basis of life

Known as the universal solvent, without water life on Earth would not exist. Right now, deep space probes are searching the far reaches of our solar system for water while three quarters of our own planet is bathed in it. Every living cell contains water. Every living plant depends on it to thrive. This book is about water. How to manage it, infuse it with the nutrition vital to plants and deliver it to their thirsty roots. In nature, fire and water act together to recharge the soil with...

When growing outdoors

Protect the reservoir from heat and direct sunlight. Maintain solution temperatures between 68 and 75 degrees F. You may want to bury the reservoir to take advantage of the cool and consistent soil temperatures. You can use aluminum foil to reflect sunlight and keep the reservoir from getting too hot. In really hot climates, you can create a cooling loop, buried in the soil to dissipate heat by having the nutrient pass through it on its way to the injectors (not applicable for the hydroponic...

The nutrient solution

Compare the measure of a plants health to the strength of a chain, it too is only as strong as its weakest link. To insure that your 'chain' is strong, it is very important to make sure all the links are in place, and in good supply. Proper concentration of nutrients within the solution is critical, as hydroponically grown plants are completely dependant upon it for food and different plants have varying nutrient requirements. Most commercially available hydroponic nutrients now come with...
