    New build ;-)

    Current:
    2 x cxb2530
    Meanwell HLG-120-c700 B version
    100k Pot for dimming
    120mm Vedar pc fan 3.3mm h2o pressure
    100x150mm carbon scrubber

    I was going for 4x 36v cxb2530s running between 0.700 & 0.350 with the pot giving me 25.2watts to 12.6watts per cob, but have only got 2 x at the moment

    Question i need help on if its bad for my driver or not?
    Is it strange how i can run 2 x 36v cxb2530s on my meanwell hlg-120-c700 that is rated for 107~215volts????? im stumped

    Like it dosnt even reach the minimum of ~107 ...
    Its like 68~72v if that

    Strains 60dway wonder, nothing fancy just some smoko
    (Btw not grow in this box, just to make it look good)

    That looks a lot better than my first attempt at a grow box. Far more stealth. More height to fit all the things. And neater.

    And man that 60 day wonder looks good. Especially that one giant nug right up the back

    They were both grown with viparspectra300watt led - with another 3 or 4 sisters.
    I had to prune some branches off thats why its a big nug.
    And the other is missing its main cola due to my stupid bird biting it off haha
    But yeah there mean little suckers, only 1 pheno is worth smoking though and thats the one missing the cola

    As for the box yeah, its my first but not my last, i love making them

    So yeah both cobs are running at 25.5watts each..

    The cobs are rated for 174lumens/watt but i dont know how to calculate the losses from the heat and driver efficiency ( can someone show me how? im not sure on the formula )

    So im gonna guess somewhere between 120L/w to 150L/w
    So between 6120 ~ 7650 Lumens

    I was aiming for around 8000 lumens when flowering at 0.700ma & dimmed down to .0350 for veg

    Could somone chime in with a way to calculate pffd or PFD?

    So the ending turned out well i think, got myself 19grams of good home grown.

    Smells like nothing, until you grind it, then the fruit smell quickly fills the area.

    Vapes great, initial first few hits were smooth as

    So yep, new life is upon us..

    First pic is roughly 10days. Now im giving her a slight feed, nothing too fancy just some rhizo & maxi bloom with a ph of 6.5

    The next pic is 1 day after her first feed, shes tasting her food -_-

    Third pic is roughly 14 days old.. shes starting to smash her food..

    Probs feed her in another 5 or so days & include some cal mag
