Not that many but 15 and some over driven t5ho over a 3x3.
Not gonna say it's a bus full of people who make financilly responsible decisions tho.

I would think blowing cooler (drier) air onto the plants would increase transpiration, but this may also lower leaf temps dropping down the plants metabolism rate. Tough to say what the net effect would be.

Thanks for your response, I'm on the fence about this. More research is required...

Hey Bud, you near your KB-100-80's to grab me a measurement of the hole pattern.. Their website sucks from a design standpoint...I'm throwing a Ledil lens hole pattern on the bases as well. I don't want to have to drill a gazillion holes by hand if i want len's after all.
I can't help you here, we did custom lens holders so we could run them paired up.

or maybe the cxb's....... and then there are the cheap 1212's what will i ever do.
You could load up on the 1212's because they are cheap as chips but offer great value. If you drive them softly (800 - 1000ish mA) and spread them out evenly above the canopy you would have a more uniform distribution of light than say running 1 x 3590, if I remember correctly 3 x 1212's is slightly better performance than 1 CXB and cheaper, so from that perspective it's a no brainer.

With regards to colour temp I would go 3500 90CRI... Dawg is currently running a thread here and he is testing citi 1812 3500k @ 80cri and 90 cri so you could look in on that.. But my 2 cents is whatever Citi from 1212 you go with you are going to get the most bang for your buck and these chips seriously kick ass.

Awesome thread btw you have got some serious skills and knowledge;)

Edit got through your thread and it seems you have already made your decision lol!

So while I was waiting for everything to start showing up, I started digging around on the internet to find out how to raise and lower these things... Ratchets just ain't gonna cut it nor will chain too old.. too slow... 4 hanging points is a bit of a pain to raise and lower ones lights... SO..... I started looking at different kinds of lifts and things of that nature and i came across a few different idea's.. I have to build a device that lifts each 11' light bar and they way 60lb when fully dressed with LEDS and water inside. Not to shabby!!!!!!!!!! If you're knew here I have twelve of these light bars to hang..

1. Boat cranks and pulleys( 0V, simple and cheap) $50 per light bar
2. Actuators and pulleys( medium price, 12v, and controllable wirelessly) $240
3. Winches and pulleys (12v, medium to expensive, hard to wirelessly control) $220
4. "Mylifter" Smart hoists (too expensive, but hella cool, 120v, low lifting capacity) $475
5. Garage Door openers and complex chain to pulley system (A lot more fabrication, and expensive, easy to find used parts) $
6. Garage attic lifts (expensive, 120v or 12v, free controller included,DIYable though!!!!) $1000's
7.Sunwinch's ( cheap pieces of shit, made by a great old school company) $400
8. Garage Gator $200

Well I chose a combination of number 6 and option 8. The reason being because I have four points to pick as you can see in the picture below and that makes all these options expensive. Even cheap pulleys are expensive.. And they don't like to pull, and you got wires or rope running all over the ceiling.FUCK THAT! DIY TIME HOME BOY! Screen Shot 2017-03-01 at 1.49.38 AM.png

Stay tuned light lifter build coming!
