Pulling Cool Air Instead of Exaustring

Hello All,

This is my first post ever so here we go.

I want to run CO2 in my sealed room and not lose any gas through exhaust. Fortunately, I live in the north and the cold months are coming.

Running 2 x 600W in a rectangular 3 x 9 space.

Instead of exhausting the room...can I just blow cool air in from the adjacent cool room to control temps? Will the positive pressure cause issues?
Thanks for any advice

Ya that should be fine to control temps. I do something similar.

just make sure that you use a good hepa filter for your air so you don't contaminate your room. It should work. I don't think that a little positive pressure will affect the plants. Good Luck, Happy Gardening
