The dimmer lowers the current which lowers the wattage

Drivers have different efficiency rates check the manufacturer's PDF file and check, your driver only pulls the amount of voltage needed to drive whatever LEDs you have at whatever set current. So if you have an hlg 320 and only 1 cob you're not pulling all 320 watts only whatever voltage the cob re...

I don't use any nutrients, I'm a probiotic organic living soil kinda guy, and have not seen any defficiencies due to led spectrum thus far at all.

I'd say that's pretty close to accurate. They big plants are just outside of that 2 foot depth sweet zone so they're a little less ATM with the light up that high, in the 250 range right meow.

Because these are 3000k 80cri the sensor isn't picking up on some of that extra red.

I won't be adding any co2.
Testing with the black apogee original non full spectrum meter it's pretty hard to pick up over 1000 unless I'm almost touching the strip then it jumps up way high. Mostly if I'm underneath the 4x4 it puts out 750-900 in a 2-21/2 ft depth.

Check out True Northern Lighting, they're in Canada and build a few different led fixtures from Samsung strips, might be worth looking into. Check out their Instagram page!! Tons of build pics over there.

That's correct the size of each fixure is 4x4. Originally when I got those two bigger plants they we're only in Solo cups and had been under a friend's mh 400w. When I brought it to my place and put it under that led full blast 24/7 all the stems turned purple and they haulted growth. Since then I'v...

Hi there! I built 2 of my own Samsung f series strips using 20 of the 2 footers per fixture each one powered with an hlg 600. I borrowed a regular apogee par meter from my friend and was able to get some rough testing done. It seems that at 24 inches at full blast I'm getting a pretty even spread of...
