Hydroponics systems such as the Sunleaves Garden of Ease, the Planter of Ease,
and many homemade hydroponics systems employ the Continuous Aeration Technique
(CAT) which was designed to maximize levels of moisture, nutrients, and air
at the root zone. This technique requires a simple, submersible pump and a
nutrient reservoir. Plants are usually supported over the reservoir in net
cups filled with a sterile, inert growing medium such as expanded clay pellets,
silica stone, or shredded, compressed coconut fiber.
In most CAT systems the pump sits on the bottom of the nutrient reservoir and
is connected to a small tube which juts out above the nutrient solution level.
The running pump, acting like a fountain, forces some of the nutrient solution
up through the tube and onto the plant roots which grow down through the net
cups. Some of the nutrient solution is immediately absorbed by plant roots
and some permeates the growing medium. The remainder splashes back down into
the main reservoir. This simple, continuous action ensures the nutrient solution
is well-aerated and always available to plants.
Because they work on such a simple principle and have
few moving parts, CAT systems including the Garden of
Ease and the Planter of Ease are especially well-suited
for growers new to hydroponics. Its one main plant site makes the Planter of
Ease the right choice for growing large plants such as bananas, tomatoes, eggplant,
and many others which require a good deal of support. And, because it is made
up of four smaller plant sites, the Garden of Ease is suitable for growing
smaller plants including peppers, Swiss chard, parsley, basil, and oregano.
