Day 29 flower

It was actually 24" above the top of the tallest cola.

I lowered the light till it was 18" above the top of the tallest cola. Definitely shortened the coverage a bit and made me realize my light was off center

Robin or Stephen, when do you expect the next shipment of QB120s? Specifically, the Molex connector version?

That's impossible even if your light put out twice as much as a qb it simply doesn't put out enough light to burn a plant at that height.

So after several months of Hiatus i have an opportunity to get back at it.
I was looking at my current lighting, last year i bought 2 260W QB LED Kits. i am quite happy.

so today i was researching up and was on the website planning when the next round would be available. and suddenly i see the slate 6 quad showed up as available.... SHAZZAM! I couldnt hit the buy button fast enough.

now i am stuck with the choice of what driver to get.
i am installing a 5x5 tent.... there's just so many choices and i tried to use the samsung calculator but it is all greek to me..
seems running them in series is safer i get that... but is there a few simple options with the mean well drivers?
not sure if the QB288 is tolerant of a variable setting or would it stress it out to work at say 50 or 75% or would the efficiency take a dive?

any feedback would be welcomed.... thanks in advance

Hey, I thought I would stop by for an update.
The 8 qb120 3k boards were assembled on the 2 fixtures last night, it was a blast to install and setup all on the frames.
My mate added 4 boards to his 3 vero29 COBs (~210watt running on 2.1a) setup. Results are bellow, looks really slick and produce crazy amount of light.

I added 4 boards to 5 vero29 cobs (running at 1.75 max for a total of 315watt) just added on top of the existing fixture

Running the cobs on 70% and the boards on 80%, this can get extremely bright

measured temp of the boards are around 34c with no heatsinks (not required for the qb120) dimmed to 80% running on a 2.1a Meanwell driver

So far very pleased with the boards and the superb service from the hlg team.

Thanks!

Can anyone tell me why my hlg 320 1400 A is only putting out 270 watts turned all the way up ? Also does anyone know where I can find the diagram for wiring 3 QB 288s in series please @robincnn

Question. I got a 135W QB. Would it be able to grow 3 Autoflowers in a 2x2 area?

will it grow; yes. Imho I think two would be better.

gonna be a lot of plants in there, its gonna be darker because of the amount of leaf coverage, more light would help with that too.

kaptinkush956 · Nov 13, 2017

think i would get a bigger yield with only running 2 auto in there?

there; is no yes or now answer to that. depends on, the plant, how you grow them.

you just have to find out; but I can say more light wouldn't hurt you're at 30 or so watts Per sqf. you can do almost three times that in flower.

i don't know a lot about how autos act,

firsttimeARE · Nov 13, 2017

Im running 135w over 2x2 and getting good coverage.

Actually im running 130w over a 2x2. 520w total and im actually hanging on the perimeter a bit so actual area may be 4.5x4.5

I'm guessing you just miss typed that. Do not try to put anywhere close to 90w/sqft 45-50 is the most you need with these even 30 will perform really well

A 2x2 is exactly what HLG recommends for the 135w kit. You're good to go.

You need HLG-320H-1750 I do believe. That's why your aren't getting full power. You can change drivers or add another board.

When you see it on the tips, its a warning to raise the lights, the damage is minimal, let it go too long though and it will cook the buds!

Idk how all this impossible stuff happens to your plants you must have really bad genetics

firsttimeARE · Nov 13, 2017

A guy a know who is in cash cropping mode has his buds growing into his reflector on a 1000w HPS dimmed,down to 750w.

Claims its fire.

Oh there will be a fire alright.

Since we are talking about cooking plants and all
