Peach, Thanks for the tag, been following your stuff since I began. Love your new pics. I needed 27 gal res cuz blue dream roots overwhelmed 5 gal. The netpot I have for it is 6 inch square and 6 inch deep. I figured that if I put it in res normally, I would lose 8-10 gallons of nutes. I have no doubt that roots will fill half of res, easy. So the 27 gal res is probably 24 gallons of solution. Doing my weird contraptions to suspend the entire 6 inch square netpot above top of res, leaving only roots below res top.
