greenhouse with co2

I was wondering if anyone here runs co2 in an outdoor greenhouse if so how do u set it up I want to use a green house this outdoor season and I'm trying to get some idea if u guys could post pics of ur greenhouse setups that would be great

Build your greenhouse so you have enough room for a bunk... sleep, eat, and shit in that thing and your good to go! That is how I would run my outdoor greenhouse.. if co2 was wanted.
