Tranoble, what difference would it make if you did everything the same but didn't use the sealed room method and Co2? Have you ever done this before and what do you think the decrease in production would be? I am really just curious how much benefit Co2 really has compared to no Co2. I am sure it is a big deal as your crop looks amazing but I thought I would ask your professional opinion. Also, what are your thoughts on Co2 use?

I have read the entire thread from day 1 and I must say it is the best and most informative thread I have read in some time. Thanks for sharing this info with the grow community!
