you have to add pump into drain rez, and pump solution up to main rez...you need a some type of floatswitch to make it all work.
latewood Reviewed by latewood on . How to recirculate a 4 bucket waterfarm system with a res and controller? I was told the feed hose should be a smaller diameter than the drain hose. 1/2" flexible tubing connected to the bottom of each bucket for draining. Already in place. The stand alone res of the waterfarm has a 1/2" hole at the bottom. I am going to put a water pump inside to push the water out. Then use a diameter changing adapter on the outside and either flexible 1/4" or 3/8" for a feed tube. I'm going to drill a hole 2/3 of the way up on each lower bucket for the feed line.
