Thanks! I don't think it would mess you up. I would get more opinions on that tho don't just take my word for it. But, I'm assuming that as long as you stay 12/12 you should be fine. I signed up for rollitup after I started this first grow so this time I don't have a journal. I'll send ya a few pics in your message box so i'm not changing your topic here on this thread! Best of luck. OH! You should try making homemade CO2. We just made a jug lastnight. You take an empty gallon jug and fill it halfway with distilled or ph balanced water, add about 5 - 6 cups of sugar, 2 tablespoons of Active Dry Yeast and put it all in the jug. Make sure you have a cap that fits and make a hole about the size of a pencil in the center. Put the cap back on the jug. Put the jug somewhere above your plants so it can "fall" down on them. CO2 is heavier than Oxygen so it needs to be above them. Turn off all your fans for about an hour when you do this. All you do is shake up the jug a few times a day and make sure your fans are all off when you do this. Change out the jug and make a new mixture every 2 weeks. This will give them the CO2 they need and help with heat stress.
