Hello! First day posting here...
You can make your own BBB* baby!
I posted my system and stuff in grow diaries today........ don't mean to hijack but I think I built what yer lookin fer (chews piece of hay contemplatively). This particular system I encorporated my own little twist - an external pump.
It's like a waterfarm... but Bigger... Blacker... Better.
