I'm considering running CO2 to increase yields. Problem is venting the lights. I know it's not ideal, but can I just vent the lights into a far corner of the room? This way I circulate air, but don't have to worry about exchanging air from the outside (I live in an apartment so I can't cut holes in the wall, and also not having air exchange would allow me to run CO2 with just a CO2 calcualtor and regulator)
