nice setup.

i'd try to put the rez outside the cab like in front of the elc outlets. toss a sheet or a moving box over it if u have to but it'll help the temps go down for now. also you can lose the top rez for now if you want those clones won't be taking up that much nutes for a few weeks. i'd just use the controller for now and raise and lower it to mix the nutes nicely every now and again or when mixing new batches.
