    For dIY LED QBs with samsung F strip LED's, how important is selecting color temp? should i go with 3000k or 5000k or a mix of both in 1 QB setup? or just get both but separate (3000k on 1 setup, 5000k on another set up, move plants around ) and which is better for what situation?

    What are your thoughts on parallel vs series connections? i recall in school that for series, if one goes out, all of it goes out. not sure if thats true here. any pros/cons of each?

    I got my 4 288s fired up. 40% less heat to remove and 200% brighter @ only 1/2 power. The silence is golden too! Strange silence! 20180207_003623-1328x747rz.jpg

    Should the heatsink be cool enough to keep your hand on it?

    they will work fine

    I think mixing spectrums is a waste of time unless you have a board with mixed leds on it. You not blending much of the spectrum otherwise, you just lighting different parts of the plant with different spectrum. 3000k, 3500k work just fine for both veg and flower. 4000k works well also actually, I'm growing some plants under a 4k QB 120 right now

    Loading up the Quantums -------

    First in the " Mylar Room " ....
    The Peyote Cookies and Candy Dream got Flipped to 12/12 a few days ago ...
    Did dome more LST and some cleanup on them ... Continued the TIRESAS misting using a new 50 ppm mix ( mixed in ) , spraying both of their branches daily. Not looking for 100s of seeds a few apiece to experiment on.

    QB - 288 rig 90cri ( 260watt ) 3000k plus QB 4000k panel.
    Running up to this point at 340 watts ... Adding another 120-150 watts with another QB 304. So looking to the 400+ range once I get it all settled.

    Adding that panel this weekend for the flowering stage - using a different driver than what was sent with it ... Driver is already remote mounted , just need to make the connector cable from driver to board ( using a quick disconnect ) ... Need to go to fry's electronics for 18 gauge red / black wire spools.

    In the 3x3 ...... I have a number of plants " warming up " for another flower tent ( ordered another since mine 42x30x60 is full of pinholes ) ... So once I get that the ol 3 panel batwing will go in there. ( been in mothballs since November) .

    The BREEDER plants and solo cups are in there temporarily ( getting quantum goodness ) and will be there until a few more leafsets than moved to another area. GSG / GORILLA GLUE will be potted up later for consumption. Once I get the rotation back on track ...
    Plus crossing , I will be good. I figure when the blue dream get done ( Humboldt auto ) I can give the Mephisto more room !

    Actually, I'm making fem seed of my Blue Dragon, and in another tent, I'm breeding a ducksfoot x ducksfoot cross, and making fem seed of my local ducksfoot.

    thanks, i recall 3000k is good for flower specifically. does veg care as much / will it make a huge difference if its 3000k instead of its optimal 5000k?

    also, is there any benefit of splitting the middle and going with 4000k or mix 3 4 5 together?

    kdt15 Active Member

    is there a reason you went primarily 3000k and then added a 4000k? what has your expereince been with temps?

    kdt15 Active Member

    can you explain what you mean by mixed led's? do you just mean different brands like samsungs and some other stuff? (also curious why it would no longer be a waste of time once they are mixed).

    have you tested 5000k? apparently its good for veg but i question how much of a difference the veg will feel about the color temp difference.
