Yeah, I have tried my best to stay away from the extra wiring of fans, though I do wish the new HLG480 had the 12v out like the 600. I also found that just applying Arctic Silver to the COB gave a few degrees cooler.

I am making some lights right now and can tell the difference with the cheap paste vs the Arctic Silver one. It seems thinner and less substantial. I havent tried any temps with it yet, since back gave up working already.

Just checked Starlites tests for me at the same wattage and max was 60*c. So I am happy with that.

Application and paste, I think, have a lot more to do with how well a COB works.

I ended up with too much using this paste.
I moved the cobs around on the heatsinks to smear off the excess, then cleaned the sinks off.
The cobs (CXM22) have aluminum backs, but other than that I dont know their thermal resistance properties.

I think, since I don't have anything ready, they will just dry as is? What do you think?

Here, the first pic was finished using 5000K to finish and the second was 3500k all they way through.

Eagerly awaiting your final thoughts on the difference between the two.
They are both very pretty.

Deleaf, then let them hang or wet trim. Whatever works!

Wow so your getting that kind of color with the 5000k chips?

only the last 2 weeks.

So is there a better potency? I was seeing people are using UVB rubes too last two weeks. Better potency apparently

Since LED's have no UV, but the Fall/Winter sun is more 4000K, I am thinking that a higher blue to red ratio for a finish might do the same as UV for finishing.

Good idea! Looks like it had a similiar effect to adding a MH to the end of a HPS grow. Nice color n frost!
You probably already know this n but be sure to dry those in the dark. Excuse me if I'm sounding dumb cuz I haven't followed along n don't know what you know. Personally I wet trim then dry.
Like your HO DIY stuff though. You do rock those big boy cobs something sweet in those hoods n fixtures you make. Props!

Thanks, @Hybridway , yeah the lights are off and I add the dehumidifier, so the room is at @ 70* or so and 55% humidity. I don't even have anything started for the next run, so the flower room is my drying room now.
Did you use the same amount of light when you switched or did you run less watts with the 5k

Cool! I've used the de-hu in the drying room before. I found that 55% will dry them to fast. I now set it to 70% w/ non-direct air flow. 4-5 days on the line before its to dry, then I start the burping process for a few days to pop the smell n get a cure set in.
Nice work!

Non direct is the key.
I learned the hard way, but those are the lessons that you dont forget

I switched the Dehu to 60% and things are still drying. The room stays in the mid 60*.
I might have some THC tests done today from HPS vs COB. Even the trimmers noticed the LED side had more crystals.
Another area he couldn't believe was the vegging. The first room is the same clones vegged under LED's and the second pic is the T5 to MH for veg with same veg time. The second is also 3 weeks a head and has more plants per tray.
