So the bottom line is the PPF of the "oops so sorry joe" boards is maybe down 10% from true S6 board? Makes me wonder how many times they get away with this. I wish you well on your build/grow.

Great video. Have you tried that yet?

At least they are not surprise inspections and they give you some warning. Much respect for having to take it all down 4 times a year and still making it look good! Good on ya!

Great shot of the girls underneath that blanket of photons! So annually you have do take it all down for an inspection? Do you take all your stuff over to a buddies place?

Great build. Mid-power LEDs are sooooo superior to T-5s. FYI, don't throw your old T-5 fixture away. Just pull all the old guts out and turn the mounting cables over. Then you can build a killer flower fixture using the flat surface of the fixture for a heat sink and the inside of the...

But 1050ma is only 75% of max eh?

Here is the thread where CobKits made some comparisons: https://www.rollitup.org/t/par-test-of-cobs-vs-samsung-561-boards.942636/

Better register the name BladeKits!

I thought it was for the whole 3-cob bar. 52 watts for a single is good. How are the 133mm sinks handling the heat?

I like the readouts. At 52 watts for 3 1212's...barely even getting above an idle! I'll be watching your build.:mrgreen:

You're coming up on 5ish weeks. Is that 11.5/12.5 a keeper? Or would you do it again?

Can you measure your a.c. input power? (wall watts)

I run 30-35w a sq/ft, 4" between strips and 4" off the canopy. Works good. Very uniform blanket a photons.

Not to piss in your Cheerios mate, but some of us have the "B" driver and just dim the lamps down rather than raise them up. Just saying...more than one way to do it.:mrgreen:

What strip spacing and height above canopy do you use?

I built for equal distance between strips all the way across. The max I run is 1.05 amps or about 75% of max. I keep my strips about 4 inches from tops and adjust the current down early on.

Great. Thanks for sharing your list. You'll be glad you got a Fluke DVM.

What are you using to mount/heatsink your strips?

That's why I get my grow media from a rockwool bog.

Suggestion? In the same font and size as HLG put "Born in the USA":mrgreen: *I think Bruce would be cool with it.
