Drivers and LED F series/H inFlux strips - best choices ??

It was just the light. They are the same.

Very nice job on the light, wondering what eficiency it is. Maybe 2.6-2.7 with all them strips.
What's the calculations to figure out the efficiency? Is this it?
LUX / 1000 * 15 = PPFD
LUX / 69 = umol/m2/s

What other formulas are there to keep handy?

I have a $35 lux meter from Amazon that I bought during this DIY saga! I've seen on RUI people using it to judge the position of the light. For example, if I was to measure the LUX with the meter when the plants are reaching/stretching for the light. I could take that measurement(45k lux), and lower the light and also dim the light to match the 45k. You would save money on energy, and less light loss on the walls/etc.

Those are converting lux to par (PPFD). They essentially give the same thing, but the second one is more accurate. Divide total lumens by 69 to get total PPF. Once you have that you can divide by watts to get PAR efficiency in uMol/J, or divide by area in square meters to get approximate average PPFD.

I did some testing with the lux meter, and here's what it looks like.


About 6" from the strip on the tallest plant

Taken at 12" from the light

The AC dayite meter at the time I took the photo's. The temps on the strips was at 105F from my temp gun directly on the strips.

Can anyone point me in the direction of some strips that can run on 2100mA? I've got an HLG-240H-C2100B I'm tryna use up.

Check out these leafs. I've never seen this before in my garden. These plants were grown from seed, and came from a indoor grow where the ac went out. That caused some of the plants to hermie, and I cracked these seeds. The strain is Mendo breathe. There was a few different pheno types that came out. A couple that are stretchy and duck feet leafs to single leafs(just like in the photo's below).

Bad genetic or much stress

That's what I was worried about.
Seems they have inherited the same hermie gene and are mutated at the same time.
It's sad because of that much effort you put into it but the earlier you remove it the ealier the others can fill the empty space.
The clouds between the veins on some of the leaves looks like a beginning mg deficit or like light stress. Whats the EC of your tap water, bro? Do you add some CalMag every now and then to make sure they got enough secondary macro nutes?
Sulfur, calcium and magnesium are just so important like nitrogene, phosphours and kali. But most of the bottled NPK nutes lack in these elements and plants under strong LED light seems to need even more of these elements compared to HPS grown plants. Botanicare and other brands CalMag products are relatively new on the market for that reason and there are still brands like Hesi which have no CalMag product listed till today.
My tap water has for instance only 0,15mS(75ppm) and when I would only use my Mills A+B fertilizer I would see for sure symtomes like yours on the upper leaves in the first few bloom weeks.
The shit is, when you can see a Mg deficit its already too late to solve it. A CalMag deficit in veg you recognize when the girls are two weeks in bloom or so. These are immobile elements that only move slowly within the plant. If they pull it out of the older leaves because they need it for the young shoots the damage is already there. You can only stop it from going further...

Ugh I'm so jealous... The way those leds are mounted is seriously so bad ass. I'm also so amazed that there's no sign of soldering pads or even traces honestly. They're just so Clean!!!
You can buy epoxy and paint it onto your other strips if it gives you a hardon.

Hey do you guys think 3x H_inFlux L09's gonna be enough in my 2x2 tent? I'm planning to run them with ELG-150-42A. Which gives me the option to use same driver for new oncoming https://www.samsung.com/led/lighting/led-modules/industrial-light-module/horticulture-linear/# So I can just switch 3x L09's with 3 of these on same frame and driver if I decide to. Is this a good idea? I can also add the 4th strip later on and run them more efficent if I wanted to.(almost 0.9amps at max)
