Growing with no air intake and exhaust? And without supplemental co2?

You need one of these by code in some cities. A make up air unit is a heater that can heat from -30C to 22C, basically a furnace that can keep your place warm as it brings in air. If you’re exhausting more then 500 CFM your furnace won’t be able to handle cold temps and you’ll eventually loose all your warm air. I’ve heard of people linking two or more furnaces together bringing the air back in and chain them to keep up with the exhaust.

I think wine fermentation is a month or two, you can get quick yeast too for spirits that will be about 48 hours.
