Cool. i made one last year but I guess I placed tower in a bad spot and didn’t get the even growth I wanted. Had that one in 15 gallons but root chambers and tank were hotter than I wanted. So canceled that one .
just added screen and clear liner, and a door . will add air circulation , just thinking how I could get a small heater in when time comes. as long as rotating motor doesn't give out , this'll be my veg box .
Attempting at a rotating vertical column out doors. Will be enclosing 2x2 frame with clear liner. Recirculating pump running through center. Column suspended and rotating on timer.
