CO2 question

[SwissCheese79]

I have a never used co2 in my grow room before and am starting to think I want to. My question is can I add co2 when the lights are off??? Don't think I want to add during light period as I can't turn off my can fan cause my room temps would go into the high 80's low 90's. Any input would be super!!

Btw first coco grow and I'm loving it,!

Plants produce Co2 in the night time period/lights off !

When its day light or lights on period plants use Co2 for growth...


In the past people have mentioned using extraction fan on a timer along with Co2 injection/discharge unit optimal Co2 is aprox 1500ppm.

Other suggestions is brewers yeast and sugar in a 2 litre bottle etc some times you can find Co2 related stuff in hydro online shops !



I don't worry about Co2 myself bit difficult to get optimal results with out a true controlled enviroment ! fresh air has got plenty of Co2 in it providing ya got good ventilation going & once ye get into a lil bit of super cropping... ya won't even think about the stuff

CO2 is added during lights on because it's a part of photosynthesis.

They intake CO2 and release oxygen.

Typically if it's a tank you won't leave it running non-stop, it will go off in intervals, and at those times you can set your fans to turn off, also put backdraft dampers in to keep CO2 within.

Or if you're a smaller grower just get something like the Green Pad.

Thank you guys!! I think I'm gonna stick with no co2 for now and continue to LST and super crop. Everything seems to be running good. Maybe in the near future I will add to my system
