Ive recently been wanting to get better at this craft and I'm wondering if I should put the extra effort and get a co2 tank and regulator I've seen on here where people don't use it and some that do.So the question is should I or not and if so how long would a 20 pound tank last if I seal my 4 by 4 tent and do I use it through the whole growth cycle?
