sorry for noob question

Im in a small 1 bedroom apt with my gf and im thinking about adding 2 or 3 homeade co2 2 ltr bottles in the growroom which is the laundry room which is connected to the kitchen. Thats not enough to get us sick or die or anything is it?

Also, what kind of yeast am i suppose to buy and what section of walmart is it in lol. thnx

They hardley put out any c02 an arent dangerous.
The diy co2 is kind of a waste if its not a sealed Cab With a hell of alot of light.

I use bakers yeast an regular sugar. 2 Tablespoons yeast, an 2 cups sugar in a 2liter.

ahh ok thnx. well my area is not sealed and im only using a 600 watt hps. i wonder if it would be a good idea to put about 10 of them in there since they dont put off too much
