Cheap Solution to CO2

Hey guys I'm about to harvest my 1st plant ever and I have a few more generations vegging/flowering. I want to get into using CO2 but I don't know enough about it. a few questions for the experts

1. I grow in my bedroom is this a no no for using CO2 (this sounds like it's the worst question in the world.)

2. I live in a major city. Would it help to just open my window for a few hours each day?

3. If i can use co2 in my bedroom is there a cheap way of deploying it? I have a 2' x 3' x 6' cab and some smaller boxes that I veg in.

Thanks for all your help!! this site is sooo much better than IC

Hi there, I mix 3/4 cup sugar, 6 cups water and a pinch of yeast (roughly 1 teaspoon does the trick) into a 2litre plastic bottle(u can go bigger than this if you desire). The exact ratio of ingredients is not critical. For example, I use enough water to fill the bottle to about 3 inches from the top. You don't want to get the mixture too full, as the mixture may foam a bit, and you don't want the foam flowing onto your floor.
Using the above mixture, I regularly get 3-5 days of strong CO2 production, at a rate of one bubble every 3-7 seconds. When the system stops bubbling (the drop in gas production is often precipitous), dump out everything and mix up a new concoction, its that easy.
Hope this helps?

"how to make co2 generator" is what you type in the search bar. alot of people will say you have to have 1500 ppm for it to be effective, but im using one like you will see anyway. i believe any is better then none at all. i placed the outlet above my fan to have it blown throughout the room. just like slimjim says
