    Willl someone please post a link to that colored light spectum chart that shows where each differnt type of light falls and also the one showing what parts of the spectrum the plants needs/uses during the different stages?

    I gave my last copy away and now can't remember where I down loaded it from.

    Thank you.

    Fruitybud,

    Thanks. I didn't see the ones I was thinking about, but some of these are even more informative.

    It is important to understand that Hicks chart is in reference to ideal black body radiation. Bulbs that produce light by electrically heating a resistive element approximate black body radiation reasonably well. Flouresents do not.

    This is important because a leaf's chlorlplasts cannot use all the frequencies in daylight. A leaf appears green in color because green light is of less use to the chloroplasts and is reflected back to the eye.

    ive never had that less of light b4 lol ..
    usually had 2-3 32w+ t12's around.which that would be enough for sure for a bit....

    i would say if you keep it close they will do for the 2wks..
    and NO they will not do you for flower... seedlings n clones is what there good for..
    HPS all the way my friend for flower..
    what size of room you doing this in??
    you getting a inline fan?

    This is full spectrum of Mars light. I did not study spectrum too much, but my girls grow very happy under this light, I harvested 1.2g/W.
