I'm studying up on the hydroponic system for indoor growth. In particular the bubble bucket method.My big drawback is in size of the setup. A 3.5 gallon bucket is pretty tall, much taller than a indoor soil set-up. My currnt set-up is limited in height, and I don't want to build a new configuration. What would be the approximate height requirements for a 3.5 gallon bubble bucket set-up with the plant at maturity? Any help would be appreciated.
