DSA, your setup is similar to what I’ve sketched up here, I’m looking to keep the res out of the room, connected the 4 pot via 2’' pvc, and a 1'’ return line, pulling water by a 290 gph pump to a chiller, then exited to the res. cycling back in to the 4 pots... i figure as long as the res is leveled with the 4 pots, even tho I’m using a 2’’ TEE inside the room dividing the returned water...
question is, do you think this sketch is a Recirculation failure? or you think it’ll work?
id like to not use a water chiller and save the 300watts, but I’m not sure if even having the res outside of the grow area will still keep temps down to 65-68’, id have to keep the ambient temp of the res area around 70’, which might not be too difficult... decisions..decisions...
