    Thanx, Green. I'm coming to accept that the LEDs are at least a factor.

    You say you use 2 x 300w LED panels, is that real 600W power draw from the wall?
    Or more likely "300w" in Chinese means about 90-150w power draw?

    Considering one can get about 0.8-1.2 grams per watt, it seems to me your grow is perfectly fine.


    If however it's really 600w draw, it might be anything from strain to CO2, to nutrients, to temps, distance from the lights etc.
    Seeing how the plants looks quite good, if you can grow the same strains only this time supplement with CO2 to see if it makes a difference.

    Thanx, Baracus. My current LED setup only provides about 33 watts / sq ft. Do you all think that adding another panel during 12/12 to boost the power to ~50 watts / sq ft will help significantly?

    I would do away with them panels mate and go fr COB leds if you want a half decent result with them... just my opinion

    You are, of course, correct: The 300w is more a model number rather than any meaningful measure of power draw/output. The *actual* draw at the wall is ~132 watts /panel, so 2 x 132 = ~264 watts, or about 33 watts/sq.ft. *actual* total draw. As I asked Baracus, do you all think that adding another panel during 12/12 to boost the power to ~50 watts / sq ft will help significantly?

    Hi skeptic it really is not about the watts per square foot or the amount of lumens your light's put out. Its about micromoles a lot of people over look this when switching to 12/12 you lower your micromoles by half so a light that done well in veg will not always be sufficient for flower. Of course light height can play a big part in this as well. With leds often the footprint is considerably smaller to achieve the umol necessary yo grow dank weed. I can not remember the exact number off my head but im sure you need to produce over 500 umols to grow decent weed and around 700-800 for dank solid buds.
