I was reading a post about someone using a fish pump to blow air out of their grow cab - which got me thinking.
Say that air pump was attached to a long tube (say a half inch in diameter, and 3 feet long, coiled up. Now say that coil of tube was filled with actiavted carbon powder...
If it works, it would be a $20, almost silent, air scrubber / exhaust.
Anyone tried something similar?
