  • hey airwalker i have question about this quantum led 480w i have it around 36" from the tops of the seedlings at full brightness and temps are high is it better to lower the light and lower the brightness? You seem to be the expert on lights haha. Thanks in advance.

    Higher temps is what you want with LED. 80-83℉ is ideal.

    @spark1015 leave it @36" & dim to 50% is best for seedlings
    Hey, airwalker extremely new to growing (2 runs)and was about to order 2 opticps. Ur post have made me reconsider Them a lot. Is alibaba site legit to order from? Much appreciated any advise
    However, this has a bit higher watt usage than I initially wanted + it also has a bigger recommended coverage area than my tent. My idea was to dim it down pretty low on veg phase (25 up to 50%) and then boost it up to 75% on blooming phase. This way it would draw around approx. 225 on my max and would result in less heat and longer lifespan as I would never use it on full. What are your thoughts on this? Thanks!!
    Hey Airwalker! I've read in some threads you have some pretty hand on experience with the Mars Hydro TSW2000. As my space is limited, I will have to use an 80x80cm tent. Originally I wanted to go for the Lumatek Attis 200w, but it seems to be out of stock everywhere, so I am considering the Mars Hydro TSW2000 instead.(continued in 2nd post)
    Hey sorry to bother airwalker 16 i am new here still trying to figure out my way around here. Someone sent me your way i am wondering if i could safely use slate 2 QB heatsinks for cobs like citizen clu1212 or cxb 3590s if so how many per 1 qb heatsink and what is safe abouts to run them at. Any help would be much appreciated.
    Sir,

    I would like very much to DIY some LED lights. I really dont know much about it, but im trying to learn. Would you recommend still using Cree3590's or would you go with something newer like the luminus cxm32 gen4's, the vero's or something else entirely?

    Thanks for your time,

    COBs are great if you already have them. But if not, you're better of using strips or boards. The spread of hundreds/thousands of diodes can't be beat.

    i am starting everything absolutely from scratch. i just finished framing the rooms. and am currently using HID's in tents.

    Could you recommend some strips or QB's or a good place to get them? I was told, or read that the cobs penetrate better than boards/strips, is this no longer true?

    The coverage on strips is way better, and you can lower them and run the softer for efficiency .Get a light meter. Multi source lighting will penetrate better than one fixed point.
    Hey mate,
    Im trying to light up a 4'x2' area and I want to use strip lights... just wondering what you recommend as the best bang for buck strip modules available as of right now, how many and what driver ?? Also should I do a mix of 3k and 4k??
    I already have 4 x CXB3590 fitting that I made for a cupboard grow but found the light to be too concentrated and bleach.
    Thanks.
    Hey man. Is kingbrite qb288 29$ quantumboard running at 150 watts better than 3 clu 1212 at 150 watts ?

    Is there really a huge difference about the two ?

    Airwalker16
    They're not even the same form factor at all. Ones 100-200 diodes packed into a space of like a square inch and the other has 288 diodes layed out over an 11"x7" Board.

    Hey man. Is there a way to private message you. I’d like to send some pics but I’m not sure how I feel about posting on internet due to state laws and whatnot

    First time grower seeking direction.
    Curious if my light is too intense for plants?
    Super dense!
    If I'm going to be hounest iv only been growing a little while haven't got a ec tester yet I feed them professors a and b five mil each a and b per littre
    Hi Airwalker, can you give me parts list for an 8 bucket set up like yours? Its going to be for a 4x8 area but the room will be 5x10 so I have a foot to work around. I would greatly appreciate it. Thanks.
    air walker,
    has anyone put together the different lifetimes of the 3590s at 700, 1400mA, 1750, 2100, and higher?

    i've always run them at 1400 but i am considering the higher amperages for more brightness and I'm just trying to get my head wrapped around the disadvantages of doing such. you know, aside from the additional heat i'll have to manage. any insights you can offer is greatly appreciated

    Heat will the be the ultimate factor in lifespan. Technically a higher current than 1.4 amps up till the Max current can have a life just as long, but you will expand your energy usage exponentially to cool, as you continue to run higher and higher currents. Math all in the datasheets technically. I still think 5-10 years is an easy reality even with uneven cooling. Later.
    Right now im about to create a 8x8 sealed room and want to make sure i have more useful lights than 4 1000 hps can give me. im here from this thead
    Limo's CXB3590 build
    So in terms of 500 watts in your 4x4 can it at least equal a 1000 watt light? whats the weight you got on that sq area using 500watts of cobs? in the area of 4x4 with cobs vs traditional hps are you getting the same yield per sqft?

    also how long do you veg for using dwc buckets i think 9 plants in a 4x4 is kinda overkill but since you did 9 plants you should be able to flower after like 1-2 weeks in veg. you should top the plant once it has like 5 nodes. dont waste time vegging longer you the net would only need to be about 12-15 inch from top of bucket and can be spread more evenly
    P
    PotHead3
    you should have also trimmed the lower part earlier cause those stems are like a jungle and is wasted energy that could have been spent on the branches that you keep. i dont like doing big plants as it waste electricity and time you get more for your electricty using more plants spread out evenly with a short veg time.but anyway i cant see anything on the thread regarding my initial questions

    Just do a 3x3 layout for 9 cobs. And my layout is perfect. I do not get hot spots.
    Hey bro, did you ever check out thedankden.com. Its very Chill. Not what people are used to. Just thought Id throw it out there.
