I converted mine to aeroponics. Hydro needs 25 gallons, mine only needs 5 gallons. I added a pond pump and 1/2 hose a foot long. The air bubblier is supplied to the main tank only, the reset of the air hose is used for irrigation. I 3d printed a 1/2" to 4 4mm hose barb manifold. 3D print 4 drip rings with 4mm hose barbs. Used the black air hose to supply water to the drip rings. added a 24 hour timer good for a setting every half hour. set to 1/2 hour of water pump every hour. The return hose at the bottom of the bucket is used as in the directions. The main bucket has the air stone, water pump, and water manifold.
So far the results are great!
