The blue pump in the 3gal bucket is a little giant with a built in float switch.I call it the repump bucket. it has the same water level as the grow buckets minus the 2x2 blocks they set on.( I am experimenting with diff water levels in the grow buckets, none to 3 inches deep) it returns water to the blue 25gal nuit tank.
this is my new veg,under an OLD 440 watt 8'VHO floro
