    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

    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
    [​IMG]
    Running the cobs on 70% and the boards on 80%, this can get extremely bright
    [​IMG]

    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

    [​IMG]

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

    Thanks!

    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.

    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,

    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!

    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
