if in USA Lowes has like 25 gallon totes for like 11$ get 3 of them use two for plant sites 2 in each and the 3rd as control rez. Get at least 2in pvc for return line. Tractor supply has the bulkheads to make the connections then ¾ pvc for your supply line connected to your pump. If you have any diy skills it's pretty simple
how low should the pvc be run into the square tubs? Id imagine pretty low to help with getting all out. Since this setup is non pump driven, is recommended drain technique just to run a hose connected to water pump to suck each res dry? Or does it not effect things all that much and im overthinking it
Yeah that's the one part that is a pain. If you can raise them up a little you could but a drain In the bottom. I just use my pump to pump most out then shop vac to get the last little bit out. I don't do many rez changes tho. I put bulkheads as low as possible
I've seen some people use flexible hose . Do you think that's better or stay with PVC? Can't afford leaks!!
If you’re going to use bulkheads, I’d suggest 2” or 3” current culture bulkheads. They have really cool setups and aren’t hard to replicate if you can work with your hands. This is what mine looks like, I just have it in a 4x4 tent now. It’s worth looking into if you want some other ideas.
