So what happened to the Stanley fan you scored? Use that instead of the computer fans. My plants are constantly moving. Pretty much a whirl wind in there but they aren't being jostled a lot. But all leaves are moving...some very little but you can see there's air movement. I've got one fan on the shelf the plants are on blowing up and bouncing off the back wall and another hanging top of canopy high blowing out the door (door is open a little). Then I have another fan outside the area blowing the cooler air from floor level into the room.

"Lumen burn"...that's a new phrase. Did some searches and can't even find one reference to "lumen burn". A lumen is defined as "the amount of light a candle will cast on a one square foot area from one foot away". So it isn't lumens you should be worried about with CFL's. And if those are 43 watt CFL's then you're only putting out a little over 15,000 lumens, which is low for the size of the grow area you have and for sure isn't making the surrounding materials so hot they're burning the leaves (leafs).

So what is your fertilizer schedule? To me that might suggest why the tips of the leaves are all burnt.
Marc Benson Reviewed by Marc Benson on . HST Question is for Zandor or anyone whoâ??s done pruning. H-man? Pics show first grow box with plant 30 hours into SCROGinâ??. Still 24/7. HST?? Yeah. Cause it was like tieing a screaminâ?? toddler into a crip. Heart ached at every tug and pull. You can see by other pics it looks like I should have plenty of room to try a few clones. Will have to rework lighting and put in a partition. Including pic of blower I got for $17. Should work good after one end of intake is taped off. Rating: 5
