Hydro Questions

As you may know, I want to gather as much info as possible til I feel comfortable to try a hydro grow. I have come up with a plan that seems really, really, really simple, its a dwc system that I'll make myself. there are no pumps, only an airstone or two. I'm thinking somewhere between 4-8 plants, I havent figured out yet the optimal amount yet to grow under my 400 watt light, any suggestions on this one? I'm afraid it might be 4.

The other thing I am, confused on is the nutes. Are nutes different, I mean lets say I have some foxfarm left over from my soil grow, can I use them, or should I be using "special" nutes just for hydro?

Do you have any comments on going dwc?

Foxfarm makes nutes for soil and hydro. I would use the one they say to use.

For passive hydro systems like DWC, think about using a separate system for each plant, so you can move them around easily. Kinda like GH's waterfarm, which is separate drip buckets.

yeah just make sure it is ment for hydro ask the clerk, say your growing Vegtables and fruit.
