Two gallon pail with drain valve, lid with holes to accommodate 9 pots, Air pump, Air hose, Airstone, Nine plastic net pots, Grorox, Nutrient and the Trellis Kit. The Air Farm is a simple soilless growing system. It consists of a 2 gal. They can be used without the trellis for annuals, perennials or vegetables that don't require support. Operation The plants or seeds are planted in the net pots in the Grorox.
Air is pumped through a tube to an airstone submersed in the nutrient solution.
This creates bubbles in the solution. As the lid is a sealing lid, the air pump creates positive atmospheric pressure in the tank. This escapes through the Grorox, carrying nutrient soaked air up through the rocks. Once the roots grow into the airspace between the pots and the solution, the bursting bubbles bathe the roots in solution. Eventually the roots grow into the solution.
