i was thinking about moving the inner tote to a tray res one day so if i put holes in the floor it would limit future uses. im leaning toward the "tub in tub" method now and im thinking of having a 2"x 0.5" vertical hole in each side of the inner tub, this way i can put a little mesh over with ease, the holes should be large enough to flood the tub, though it may prove easier to have four large holes, my only concern is that the res tub will never dry out so after watering, the run off will mix with whats left from the last watering and so on the whole way through....
but i like this aswell ...
i would like this setup but with a larger res and maybe some tubes connecting the run off to the res but tbh this may be a test of my diy skills and my patience
