room temp 74°F
temps at trellis level in the middle of the tent with ZERO fans running: 80°F
temps at trellis level in the middle of the tent with 12" fan blowing and 6" 240cfm exhaust fan running: 77°F
aluminum only slightly warm to the touch, if even. can touch and hold every part of the frame with no problems.
this is going to be awesome not dealing with HPS heat

added a 2nd exhaust fan to the tent and got temps even lower 
runs 68-70°F with about 400cfm exhaust. might be too much, lol...

just got it all up and running. veg area is not doing so great at the moment. need to dump, clean and refill so i think i will add some babies in this tent and see what happens.

so right now i am going to veg in this tent until i get something big enough to flower.
not sure if this will be my final lineup for flowering yet or not. when i do start flowering, i will start a new thread.
2 - Ghost Train Haze #1
1 - MK-Ultra
1 - Bogglegum
the MK-Ultra is female, but the others are from seed.
these plants really looked much better after a night under the F-Cloak. Really perked up

also, i have shut the exhaust vent off 
tent is running at room temps of 72°F with only a 12" fan running inside the tent

You may discover that you'll need more heat. The general consensus around here seems to be that, due to the lack of IR in these LEDs, you should maintain a higher canopy temp (low 80's) to aid transpiration and nutrient uptake. That said, I know some have good success without raising temps. Not sure what makes the difference. I can certainly say that I saw a significant difference in plant health once I got temps over 80.also, i have shut the exhaust vent off

thanks
during the summer months they will get close to those 80 degree temps. right now, i would have to add some kind of additional lighting to achieve higher temps

actually i just went and looked at the thermometer and its running about 77-78 °F with room temps around 72-73.
colder nights will bring slightly lower temps however

Hi, SW! I've a picture for you...!
I would call it: photosyntesis under different temps and intensities!
As you can see, a plant getting 500μMol/s@30°C can grow as fast as the same plant getting 1500μMol/s@20°C.
What @Humple says is based on this paper and we found out it is true in the most situations.
By the way, everything looks very good! I am sure you will enjoy how your plants will love it!
These strips are awesome, no bleaching but intense light from everywhere, you'll be impressed at all.

thanks, appreciate the chart and the help in understanding the where the peaks for photosynthesis are.
plants loving their new home so far

So will 500-600 umol flower and yield as well as 1000-1200 ?
500umol @ 30c will flower the same as 1500umol @20c. But 1500umol @30c out yields 500umol @30c as per the graph.
I would like to know if co2 can be overlapped with this? Or that's a separate thing all together?

Im currently on my second LED run with three very different phenos of HSO's Blue Dream, and I've noticed that one of the three seemed to shrug off cooler temps with ease, while the other two really struggled. So - as with most things involved in growing weed - it appears to sometimes be somewhat strain dependent.

Mate, that's some cool info, may I ask for the source paper of the diagram?
Thanks

I have to first search my downloaded pdf's, if I find it, I upload it here. Unfortunately, I can not remember the exact title of the research, but I recognize it when I see it ...
