Thank you so much for your insight. I need to keep telling myself to slow down.I think I would recommend that you get a couple grows behind you without CO2 at first. The problem with CO2 is that it is like installing a massive HP upgrade on a car. It goes fast, but it also points out all the weak spots like tranny and driver capabilities pretty quick. First time growers should probably try to keep it down the center of the fairway nice and easy at first, then once you are getting good look at what is the next thing you can do that is the biggest influencer on what your goals are. If your goals are fast and big, CO2 may be for you. If your goal is top shelf high THC bud, CO2 will have no impact and will only cause issues. At least that's my opinion, take it for what you paid for it.
I shall keep doing my research.
