    Combined LED and HPS Grow

    I have been building and experimenting with led panels myself since i started growing and gradually gaining experience in all of this, and to answer what your saying here the more you push the led the lower the efficiency, so the lower the efficiency the more heat is produced and the more heat...

    whats the best spectrum

    So basically I should be putting 4000k neutral white in place of any blue/white over 5000k? Before now I've always used 450nm and 420nm at a 2:1 ratio and used like 30-40% blue which from reading that is completely unnecessary

    whats the best spectrum

    Would this mean I would benefit from a couple of 730nm leds along with the 660nm leds in the same panel or is the 660nm going to be too low to take much of an advantage from this?

    whats the best spectrum

    I just looked up the emerson effect and came across this which I have never read before and does sound like it's worth investing more. 'The yield obtained using both red and far-red light simultaneously is much higher than the sum of the yields obtained with red and far-red light separately...

    whats the best spectrum

    Ah yeah sorry thats what i was meaning, deep red not far red,i will eventually be getting a 10w 730nm led to see if it does help atall and do you think theres enough blue in the 4000k lights for the plants as ive found that not enough blue in the spectrum does make the plants stretch a bit.

    Is it possible to take apart a UFO grow light and rebuild in a custom shape?

    it would be very pricey to take apart a ufo light to change the spectrum and would require probably less effort to just build your own array. I've been speaking to vanqled after Bumping Spheda mentioning them as i was considering using these 10w leds. They were saying 10w red and blue = 3:1 led...
