im using a 4gal container with 3" net pots and I have zero complaints. For the cabinet size you can get still get a great yield out of 28".. good luck!! and lovemy stealth cabinet is only 28" tall, so height is an issue.
I have a 4.5 gallon rubber maid container that is about 6" tall and Iam planning to use a 3" net pot with my DWC bucket will this work?
