i'm still just dealing with my DWC bins individually, once i get my plants sexed and i begin production, then will be time enough to really understand how to make a recirculating system.

in truth, i plan on a SOG using 4x5gallon bins with buds in differing stages of flower so, wouldn't that mean different feeding schedules?

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
