do i need a co2 emitter ?

Running a closet grow. The doors usually stay shut, do i need some thing that produces c02 inside the cabinet, or are the small cracks sufficient to pull c02 to the plants?

Temps and cooling are good and i have a carbon filter inside the cabinet


Thnx. English sucks cuz im on my phone

I'm in the same position you are and never had to supplement C02

It's like a new sport car you don't really need it but......

If you are inside your home, it is getting more than enough....probably can average 400-800ppm this way....
