I second this... all i have read about hydro and yields and health come directly to bubbleponics. basically a steady drip line pumping (no timer or anything) and a DWC resevor that the roots grow into entirely... So all that is needed, is a rubbermaid large enough for however much you wish to grow, or many units. A single water pump for each system, x amount of drain pots, (whatever medium you want to use in them) some tubing and your done. easy as fucking cake. take your clone or rockwool cube grown seed, plug into medium, put dripper on it. and watch it grow... as long as you have a halfway decent nute system going 50-75% strength, and keep your ph in check periodically, its almost fool proof. way more controlled than buying random soil and hoping there is enough of this, and not to much of that etc. plus with hydro because its always there when the plants need it, you get 2x3 times as much results (from what i have read) than standard soil... I dont know jack shit about the prosess of what or how much you really apply to hydro, as all i do is water my shit with liquid nutes twice a week, and hope they hit the right spot in the soil.
