Beautiful! Everytime I come to this thread it makes me wish I would've got a bigger tent! There were no DR80s in stock and I had no room for a DR90. BLAST YOU! I'm quite jealous!
Feed them some Phosophoload. Go easy with the nutes if you do. Bet yet Foliar feed em some Bushmaster instead. Either way go easy with the nuts and raise the light high as possible. I'd do it right before lights out or 2hours before light on. They'll stop growing vertically instantly. Oh and do it two feedings. With a straight water feeding between. Good luck with your girls.
..speaking of fans..
Just ordered two Air King 6" clip-on deals from Amazon .. $40, shipped, for the pair.
There were cheaper clip-deals available for $12 + shipping.. But a friend has had two 12" Air Kings on 24/7 for the past two years, .. No issues..
Can't argue with results
