Perpetual autos in same hydro tower

EC of 3 for a baby plant is overkill. you would prob have a better time doing this with photos and just taking clones off of them as you flip to flower. two tents. But you want to stick to autos you will need separate towers I feel for the young ones and the old ones. I have seen something like this outdoors withing a strawberry tower planter with fastbuds autos. It was in one of their contests years ago. it was ok. but the plants did not get to their full potential from lack of root space but it looked neat.
