Nice to find someone experimenting with spectrums. This is the very reason I decided not to get another LED. I get to play Sun God!
The Myth About Green (~ 500-600 nm), GSL (LED mfg) now incorporates a few green LEDs into his lights. He calls his lights 'Quantum'. From his website...
"Many scientists have long believed that plants absorb little to no light in the 500-600nm region of PAR, however new research has shown that light in this region plays a vital role in growth times, yield, and photosynthetic efficiency.
Plants convert light energy into chemical energy in a process known as photsynthesis. Two compounds, Chlorophyll A & B, are primarily responsible for this conversion process. These compounds absorb blue and red light most efficiently, and have the highest conversion rates at 439nm, 469nm, 642nm, and 670nm. Our Quantum lights target all 4 of these points, and then take the science one step further. Multiple tests have shown that plants absorb more red and blue light in the presence of green light, yet we are the only company to focus on this occurrence. Research published by NASA verifies that when all 3 regions of PAR are balanced properly (400-500nm, 500-600nm, & 600-700nm), flowering times and yields can be dramatically altered..."
and with that I have been on a quest for 1-2 4ft HOs to add to my mix. Anybody?

dude.... i'll just beat down 80% of your shit with this ONE post..... ok?
THIS is what BROAD LEAFED PLANTS need. not JUST marijuana......
View attachment 1656967
Veg plants need 5k-5,500 and flowering plants need 2k-3k. these are the BEST spectrums of light for plant growth, they are the spectrums used in Comertial greenhouses. on TOP of that, plants CAN'T absorb green light. none of the chlorophyll's can absorb it, makeing it impossible for the plant to use it......
get a job in a comertial greenhouse. you might learn a whole lot. i know i did.......

ACTUALY its Chlorophyll A,B,C and D. C and D allow for VERY LITTLE green absorbtion, less than .01% of anything, seeing as C and D only take up around 1% of the total plant structure

I hate when people use information like a stick to beat people with ESPECIALLY when the information they use they dont even understand! im going to dismantle 100% of your argument with what we call scientific FACT.
1.) THe Kelvin scale you use, which is laughable
is called the Kelvin scale for a reason. It is based on a black body radiator like an iron pot being HEATED TO A CERTAIN TEMPERATURE TO EMIT LIGHT.heres some photos and graphs so you can actually learn something. ANY BLACK BODY RADIATOR ie lightbulbs CANNOT PRODUCE THE FULL COLOR SPECTRUM!
2.) Green Light Drives Leaf Photosynthesis More Effi ciently than
Red Light in Strong White Light: Revisiting the Enigmatic
Question of Why Leaves are Green..If you wont believe me believe people WITH PHD'S AT OXFORD UNIVERSITY!!!
3.)Chlorophyll DOES INDEED ABSORB GREEN LIGHT VIEW GRAPH BELOWView attachment 1657624
4.) Quit your job and go back to school

jesus, this thread is still alive? good job proffessour, I hope this thread turns out more like a "show and tell" thread with lots of pics than a "your theory sucks dude" thread. (meaning: more updates!)

Thanks Pr0f. Do you think one will be sufficient, or should I get 2 for my 8 bulb Quantum Bad Boy 4ft? I am getting the room ready to grow under the BB, but it is too hot here this time of year. Won't crank back up till late September, unless I can swing a portable ac. I have seen one advertised for < $300

great thing about the badboy is you can use one side at a time.. i would suggest running one side for veg and when your ready to bloom turn on other side its what i did when its too hot! my temps without ventilation hit about 85-90 which the plants dont seem to mind in soil. so long as the roots stay cool and watered... you should look into an evaporative cooler! cheaper to run! no exaust either! ive seen an evap cooler "swamp Cooler" modded to hold 50 gals of water! they use less power and can cool quite well with enough water !

what kind of light setup do you have? what bulbs etc?

evaps can bring temps down about 15 degrees depending on the size of the room and since this is an attic area how much space are we talking in SQft
