Good afternoon, Once again, Ckbrew, you've been a great source of information...
I found that my plants had actually grow up closer to the lights than I thought and had to move them up a few inches, which brought the temp down a few degrees, I can see I'll be having to adjust the lights frequently.
I also moved the 6 " duct fan to the top of my tent blowing vertically as you recommended, and yes, the rectangular vents at the bottom of my tent are open. I've adjusted the small fans more horizontally as well.
I aimed one of the small fans directly at the thermometer, but there was little change.
I did a VERY LIGHT defol, we're talking 6 or so leaves per plant, and then I switched them to flower, they're on a 12/12 schedule now, 100% intensity, 20" above the plants, so now the fun begins.
Thanks for the positive comments about my plants, rather encouraging...
Thanks again,
