Oh yea you got enough light to grow you a good crop. It's just to use the co2 to help get a harvest a week early you need more light and hotter conditions. It only gets you a week off harvest. Not really a bigg deal or worth it to most of us. So just a little would help but not make a lot of difference. A couple little fans moving air and breathing on them alot helps just as much.

My roots are deep in Scotland, hope to visit some day.
