im currently using round, smartpot beds. i have 4 36" round pots. they each sit on a 4x4 table with drains on each one. pure coco.
Botanicare KIND nutrients with, other add-ins like, budswell, terpinator,
MOAB, occasionally throw in some
cal-mag. ph 5.6-6.0. And im killing it. ive just recently started using the beds. and have just started to figure out the nutrient schedule needed. unfortunately my room is having some ventilation and heat issues im working on. but besides from that, I love coco in beds on tables to drain. KIND line works wonders as a base nute for coco because of the added calcium.
just thought i would give my two cents and whats working for me. good thread btw great info. i will be switching to the geo pots because of the square shape and pvc framing.
