Wow, this Intelligent-Gro II 810W runs cool! I've had it running in the bloom room for a week and, Wow!
I'm honestly shocked. I've been paying attention, and people have said their LEDs are cooler, but the numbers are usually all mixed up - they often compare rated wattages which isn't fair. And I have a pretty good understanding of physics, so something that consumes 540 watts in a closed environment should produce roughly the same heat as a 600 watt device. I figured, meh, maybe a degree or two difference. Nu uh - BIG difference! I haven't logged temps, and the conditions of the intake air vary constantly, but this light is a completely different experience. Temps have been in the high 70s vs low 80s. My intake air is room temp at 72-77 which would typically produce highs in the bloom room from 80-85 using the 600W hps, an 8 point rise. With the Intelligent-Gro I'm getting half that or less, a 4 point rise. I wish I'd set it up in the bloom room right away during my heat wave! I could have easily kept temps under 85.
So, for those who run a 4x4 tent, 540 watts of Intelligent-Gro LED can easily be vented with a low-volume 4 inch flue and fan. Cool!
I'm jazzed!
I've been in a bit of a dark funk for the past week. Growing has been only marginally rewarding for awhile now - no exciting new strains to harvest, environmental issues, ugly plants - bah. I let my whiteflies party a bit too hearty and they really trashed the place, invited the entire neighborhood, etc. Most of them split when I pulled out the Bug&Pest, but the stragglers are always the most annoying. I'll do another spraying tomorrow and go from there. And then there's the mold, which I haven't done anything about. I wanted to see how it works. It's not really much of an issue for my room until the final swell, when it begins to thrive, and then it keeps the plants from completing the finish. It's also interesting to see how some strains are so much more resistant than others. I may break down and get a sulfur burner, which should pretty much toast the whiteflies, too.
This Grapefruit really looks nice.
The mistaken early drench has done exactly what I hoped it would, producing a strong early pistil set and then fading to allow the plant to mature more naturally. I followed the drench with two plain waters, then gave it a dose of Energy/Tea. The closeups are all blurry, but it really does look great.

The Carnivals, on the other hand, don't look great. I've thoroughly searched my THC-enhanced memory and I think there's a possibility that I may have overdosed 'em on Transplant. When I potted 'em, I gave 'em a good strong dose of Transplant water and I think I may have overdone it. They turned on me right after I gave them a dose of Energy/Tea a week later, which puzzled me. They started yellowing and getting stiff a few days after that, like an overdose, root damage. I also considered too much intensity from the LED panel, because the yellowing is on the leaves with the most light. At least they're finally showing some improvement. They're too far into the flip to fully recover, so I'm expecting small yields from these two, but the quality should be good if I can get 'em hooked up.
Brix is way down across the board and, of course, I have no idea why. My soil may just need to resort the biota after the big flush and recycle.

The Utopia Hazes are looking fabulous! The tall girl, UH2, took the supercropping in stride, like a thoroughbred, and settled in at about 36 inches like a good well-behaved plant. She's completely dedicated to making flowers now, and has that same gorgeous open habit that my first one had - a simple framework of branches with nodes for growing hard solid nugs.

UH1 is a surprise to me. I didn't think such an open-habit sativa could be LSTed so effectively. This looks just like any other hybrid I've trained. I have high hopes for this one.

Destroyer is starting to take a shape. It still looks like an indica dom but it has great genetics, so I'll be patient and wait to see what I got. I'll be able to take cuts in a week or so.

I have another Carnival cut that looks just as bad as her sisters. I'm going to keep it as a mother, so I don't really care what it looks like right now. I potted it yesterday.

Got another Grapefruit cut going ...

Buddha Haze took to her new digs very well - the picture of health right now.
Buddha Haze - 21 days old
Blue Blood surprised me by filling her cup a lot faster than I expected. She needed water, so I popped her out of the cup and she had roots circling already, just like the Buddha Haze - I gotta keep a closer eye. So I up-potted her to a 1.5 gallon as a reward. Good girl!

UH2 cuts are doing great ...
UH2 Cuts - 19 days old
Here are a couple of them still in water. They're growing roots after 19 days.
Carnival cuts in water after a week ...
UH1 cuts in water after 12 days ... I had to pull three of them because the stems got clear gooey rot on them, so it's not foolproof.
Here's a shot of one of my 15 gallon soil bins, about to be closed up for the recycle cook. There's 6 gallons of used soil, covered in 3 lbs of EWC and a sprinkling of Roots and a bunch of plant trimmings, then another 6 gallons, repeated. I'll turn this over several times during the next month, and then it'll wait for its turn in rotation.
cya!
my subbed list is a little daunting at times Lol, sometimes I think, "so this is what hard work feels like......." just kidding 
well, mostly kidding. 
the better yours does, the better I'll handle mine the way I see it 
I just wish I knew more about electronics/wiring... I'm kind of worried the old wiring here won't let my Mars II 1600 reach its full potential, but I'll worry about that when I get there I suppose >.<
alot of bud sites for sure!!
Good to have you here. I hope to get my plants looking more presentable soon. 
So I'll put up some good 1 inch foam and line the inside in panda film. This Intelligent-Gro II 810W is even cooler than I though, now that I've been monitoring it better. I get a 2 degree rise in temps! - 2 degrees with a stinkin' 50CFM 4 inch flue! That's vs 8 degrees with the 600W hps. So I now have temps under full control and humidity is usually ok. I'll destroy my whiteflies when I redo the room, and invest in a sulfur burner and whew, then ... I'll have everything except CO2.
