    Hey folks, I'm a hair away from pulling the pin on buying 8x15LED 405nm boards and 8x15 mixed blues boards from cutter. The build is for a 5X5 that already has 6x HLG288s at 3000k and 4x HLG 96elite, I average about 900 watts in flower. The setup will be expensive so I want to know 1.) Has anyone on here tried these products from cutter, and 2.) If it were your garden, how many watts would YOU use of the 405nms and the super blues?

    PS. Yes, I will consider adding UVB at a later date

    Boards would be mounted 4 each on the sides of each fixture

    Those are some SICK DIYs my dude. Wow.
    I personally like adding a bit of blue as well, but most people here I think you'll find are going to say not to bother with it.
    Unless you're vegging in there, which in that case would be a decent addition. The wattage is kinda iffy, because 900 is already a whooole bunch for a 5X5 so I would honestly run all 16 boards on maybe 150watts. So whatever voltage they end up being, if all the same, you can use a CV driver and if not, use a CC with a Low enough current and a High enough voltage limit to run em all. One of the 185 models would be fine.

    Hell, you might even want to consider a way to possibly add them to your current drivers, which is unlikely gruel be same voltages or fit on what you've got if CC.
    But if maybe when buying driver options for them, if you could do it in a way to maybe lessen the light on the other boards and give 50-150w or more if you want to those blues.

    the 405nm is really interesting to me as it seems to be really damaging to insects, molds, and mildews. Yes to vegging..a bit, but also I like the idea of some blue stress in late flower... the blues have 385nm, 400nm, 410nm, 440nm, 450nm, and 475nm

    I really hate having bugs in there and the few thrips and centipedes I've found are driving me crazy

    there will be a couple of each board in my main veg tent also.

    just trying for the ultimate 5x5.... My 730 nm boards arrive tomorrow and the whole setup will be run with autopots next crop. CO2 and AC maybe next year

    I am striving to run each fixture separately and will run two extra channels per fixture as I have two spare channels on my ilumi bluetooth dimming controller per fixture

    I think the blues would be a great addition, depending on your main spectrum you may not need 450nm. 430nm is a good one to have as well as 470nm. Anything that is missing from your main spectrum will help, I would not have them on all the time though. A blast of them for a few hours a day should be enough.

    As for plant response id recommend 360/420/470 or just a general wide blue band hiting more or less everything. This is only really based on reading papers not tried yet myself. But 360 and 420 both have peaks in photosynthetic action spectra aswell as the stomata aperture action spectrum. 470 cause its usually missing from leds.

    But i wouldnt count on getting rid of i sects with blue light. Once theyre there you need to kill them...

    Now now, that's not so true. If he were to implement some UvB bulbs like a lot of us on here are starting to FINALLY Play around with, bugs, pests, and insects will basically disappear.
    Small insects can straight up SEE UV LIGHT and intentionally avoid it if they can.

    Yes, uvb for sure. But adding straight blue or violet for bugs? Id prefer getting something for the bugs. And id get the blues for better tasting plants ;)

    Hmmmm.....

    • = Black Light = UV tubes
    • 368 = 368nm (nanometres) = frequency of radiation most attractive to insects
    • (twice as efficient as old fly killer tubes with a 350nm radiation)

    And thats all within the UVA range. I specifically noted UVB.

    I'm just adding to the debate as another member was sayn he'd seen insects attracted to his light. It was an agromax pure uv tube I believe.
    I don't think anyone has done enough testing to prove or disprove how the uv spectrum effects insects or spider mites in particular .
    I just read a paper saying uv-b will sort out the mites but they tend to be under the leaves and the leaves act as a shade thus they don't get harmed

    If you have mites spray the little fuckers. It's important to clean your room properly between grows to help get rid of them and that means everything including the pots. Once you have a mite problem they are hard to get rid of.

    I don't have mite problems, just a few thrips and one or more centipedes.... I read some articles suggesting 405nm kills insects at every stage and messes with fungi, molds, and bacteria..

    This would be for a newer generation of plants to keep bugs, fungi, mold, bacteria from feeling comfortable in my garden and maybe some terppy goodness

    Monterey Garden Insect Spray ANNIHILATES thrips using spinosad in it.

    I'm in Canada, spinosad is hard to get.

    Id rather spray NOTHING on my plants.
