American Agritech has developed the ECONOJET® line to provide the consumer with a high quality hydrogarden that is both economical and reliable. These simple, sturdy, durable systems have become North America 's leading line of low cost automated gardens. All ECONOJET ® systems utilize the Ebb and Flow method of plant growth. The Ebb and Flow method is very user friendly and is extremely cost effective. ECONOJET® systems incorporate BOTANICARE ® plastic trays and reservoirs along with some of the best Ebb and Flow fittings and submersible pumps available. The Ebb and Flow fittings are completely modular allowing the grower to adjust the level of water that floods the tray during feeding. These high quality components will allow for years of trouble free operation. The trays and reservoirs are all made with durable ABS plastic that have built in U.V. inhibitors, which minimize fading and yellowing from intense grow lights. All trays are 7 inches deep and have drainage channels that allow water to drain completely away from the plants after feeding. Reservoirs have built in porthole covers that make it easy to check and fill the nutrient solution.
