Bozo you think I understand this stuff? I go to the hydro store and say "what should I do?" and the BRAIN says "this" and hands me something.....I go do it.....nice plants grow.

I STILL can't tell you much about lighting and spectrums beyond what the best to use is and the VERY basics of why so don't stress.....its a learn as you go thing.
Weedhound Reviewed by Weedhound on . GH WATERFARM USERS: SIMPLE RECIRCULATING SYSTEM Ok so I was at my hydro store yesterday and the BRAIN pulls out this kit from GH that makes your w/f set recirculating!! Ordinarily this isn't very exciting news EXCEPT...... Get ready.......:jointsmile: It uses an air pump and drip ring set up to move the water through the system. You do NOT NEED A WATER PUMP! Let me repeat that part: YOU DO NOT NEED A WATER PUMP. IT RUNS OFF A BASIC AIR PUMP. Rating: 5
