this looks nice and simple, thanks moe i think i will go with the rule of thumb as this will be my first real hempy bucket lol, i want the biggest res possible but i dont want to go too high and hurt them! i wonder if its possible to make an adjustable hole on a slider type fixing..thanks for the input! this is exactly what im going for, i want to have 4 hempys feeding into a large res, im gonna have to start building some frames for them to raise them above the res, im thinking i could use the run off fro m tote 1 to feed the next tote ect ect, is this a brain fart or what?
