Sorry for derailing this thread OP i'll just answer LOC quickly, there's is an infinite way of building these systems you don't have to follow the herd.
TBH most of the heat is thrown down from the lights, the real heat comes from the drivers.
You could do what you said and have cpu heatsinks this will probably be the cheapest option.
then get some long thin aluminium u-shape beans to screw the heatsinks to in such a way that you can rotate them to direct the lights freely.
Dont go overboard with fans once these fixtures are up and running your ambient temp will only rise by about 50 degrees or 10c and can easily be cooled with inlet and extraction fans, get some fan ducting and direct them towards the lights and you're golden. Work smarter not harder

Do the power supplies put off much heat, which could easily be mounted outside tent?
Thanks!!!

Ho Lee Shit - this is one well organized & impressive test grow.

But seriously - this is the kind of research we need.
Do you have a control?

The Electric bill isn't that bad. I'm in Massachusetts and paying about $750 per month including general electric living expenses.
THEY really do put out a whole lot of light! And I've noticed the same, as you mention here. The internodal spacing is much tighter and the branches much thicker than in previous rounds with the same strains.
They don't put out that much heat, noise or anything so I'm going to confidently state that their heat contribution is negligible.

ChilLED DAY 35
ChilLED DAY 35
So today I had to switch the three ChilLED lights from 100% power to 50% power since the tops of my buds are getting bleached from the intensity. If I had properly managed their height and allowed 18 to 30 inches of canopy thickness, the distance from the light would have been greater and therefore a larger more spread out footprint for the fixtures. So instead of 1,950W we will be continuing this 4x8" table at just aprox 975W/
With the exception of the bleached tips, these buds are coming out AMAZING. No deficiencies and everything is looking healthy and deep green as they start their 5th week of flower...

WOW my friend! Each table is looking incredible! Well done! Can't wait to hear the final weight results and the smoke report! Thanks for sharing
I hope to get your smoke report on these strains as well. Second opinion always helps.
Below I have posted the same clones from each table taken at day 37 of 12/12. I selected GG#4 for the comparison this round since it's a popular strain that a lot of the growers here will recognize.
HPS Gorilla Glue #4 DAY 37
HPS Gorilla Glue #4 DAY 37
The plants under the HPS are doing great. This table would be considered the "control" group I suppose since it is located between the COB's and ChilLED fixtures. This means the outer edges of this center tray will have a bit of both lighting sources so perhaps I will be able to make some keen observations there as well.
Anyway, since I haven't put up too many of the HPS table, here's a few nice ones.

CXB3590 Gorilla Glue #4 DAY 37
The CXB3590's are showing GREAT promise. The buds look a bit more lime green than the deep green that I typically like. However, I believe this is also due to the buds being a bit too close to the fixtures. I'm learning that unlike the HPS bulbs which I'm used to, these COBs require more space to the canopy.
I was fearing that COB's perhaps didn't have enough penetration power but I was wrong on that assumption. Even the popcorn growing beneath the canopy are doing better than expected!
Thanks for following my grow!
