oh, didnt realize this was something u are marketing... how much do they draw and what color temp? They r passive I assume? How warm do they get?

It's worth the message here for anyone else interested. They are citizen 1812's 80cri 3500k. Passively cooled, I register temps around 115f in a stagnant room at 75f. With air movement temps drop to 105f. I'm very impressed with the heatsinks quality and performance.
 
Pins do a better job per gram of material as there is more surface area. My preference is as long as the fins are rated for the specific light/cob I'd much rather take the fins than the pins for the reasons above. They are a solid and will last forever. Meanwhile every single pin heatsink I have received had dented in pins and looked like crap.
 
Update: Day 12 gonna give them all a feed of 108 ppms with 6.5 Ph, I already had it mixed up for them. The OG might of not liked the feeding on day 7 or 8 but it did clear up the yellow growth, just maybe a tad to high of ppms that early. I use a tiny tubaware to slow pour under my plants to not chance damaging any roots. I had the lights around 17" and and my plants where looking s little funny so I raised a couple clicks to around 18 or 19" and they seem like they like that right now so we will see how they do after this feeding today.

Looking good pal! I raise the lights even more but that's me. Keep an eye on node spacing, if they're super close raise the lights. Just don't want to see you end up with short squat plants like I did.

If they start to stretch too much drop them back down, but I've found that those lights are a lot for a little seedling so the higher the better.

I went ahead and raised them all to 20ish" will watch and see how they do then. Would rather have a little stretch then short plants.!
