empty the top rez then lift the controller higher then the buckets to flush all the nute into the buckets. keep a eye on the buckets so you don't overflow them.

i have all 8 hooked up and have no overflow problems but you may with only 6. if the plants don't need all the extra mix then don't even use the top rez only add it when the plants actually need it.

that should help for now, but in the long run you should look into making it recirculate the nutes by adding a pump in the controller with a manifold that pumps into the tops of the waterfarms by pushing the manifold tubes through the stones and top part into the lower rez of the farms.
muddywaters Reviewed by muddywaters on . Setting up Water Farm by General Hydro Ive been hauling up filtered water to my new system for 2 days. Its the Water Farm with 8 buckets (although using on 6). I have put in 16 gallons of water. The water all drains from the reservoir to the controller below and into the buckets, the pump is working and I see all buckets are about half full of water. Where am i supposed to put the nurtrients? In the controller or the reservior? I imagine the serservoir only needs to have fresh water? Right now at 16 gallons the reservoir Rating: 5
