its worth it if youâ??ve perfected growing with out it. If you havenâ??t then thereâ??s no point as you can grow great weed with out co2.
Tomthehippie Reviewed by Tomthehippie on . co2 controller worth it? I was thinking about CO2, I've seen the manual valve release for £145 which seems ok, but the digital controller is another £120 on-top. Question is can I easily do it manually or is it too much hassle? :) Rating: 5
