This was my introduction to hydro and aero system. It showed me that spraying the bare roots was a winner :thumbsup:

I need some more advise. From the drain into the res from my 4" tube some of the roots are comming out into res is this OK or what should I do. I am not sure if I should cut them a friend says it ok its just (fingers looking for food) I dont remember what he called them. I am just a little worried about roots exposed to light in res.
