So does everyone still say tank over generator? Adding Co2 to my new sealed 4000w room (12' x 8', 4' x 8' footprint). I have an 18,000btu window AC and have narrowed it down to a Sentinel controller. My hydro store is having 25% off Sentinel products soon and I wanna take advantage of it. Should I get the VCG-27 lp generator at like $450 or go with tank(s) and regulator.? Also, if I went generator, I can have it outside my room, correct? I read these posts of added heat issues...
your right and ive thought of all that, but the reality is its not a whole lot of impact from one grower.Wait...What? said:Beer gas is a blend of nitrogen and co2.
Bottled is better for the environment, because the co2 is captured as a byproduct of some other industrial process. Generators add to pollution by burning fossil fuels to generate the co2.
Otherwise, I got nothin'. I'm not tryin' to squeeze the last few percentage points out of my yield.
