I've been wondering if carbon scrubbers would stunt the growth of the plant if it were inside, underneath, the plants. Given that the carbon scrubber is underneath the plant there would be some sort of water protection. Is air flow in and or out absolutely necessary if there be a carbon scrubber in it. if a carbon scrubber is installed into the base of the stealth growth it could have dual purposes. 1 by the means of growing and 2 be used as a dryer in its final stages. Would you not agree?
