What is the light spectrum curve absorbed by cannabis

[cture]

Need a light spectrum absorbtion curve for cannabis, need it for my diy led lighting with 100% PAR efficency. I think it will be intresting for us to see how the plant will grow and etc...

what is the lumen out put on these leds your using. and u want 400-700nm(all colors of the spectrum) for veg and 530-700(red color of the spectrum) for flowering

most of the 520-720nm range can be generated by heating up your toaster-oven, or even a remote control for your tv, near-infrared is generated in massive quantities by most standard HID lamps; heck you can even buy film sensitive to most of that range. Your toaster oven will generate more lumens in that red range than any led, not to mention any HPS would blow the toaster-oven away.

Guys! I really need a cannabis photosynthesis light spectrum. All the rezult's later, with photos and great grows. What I can say i z that i will use all colors in various proportions according to the uneque cannabis photosynthetical light spectrum to achieve greater rezults, with possibility to to modify ligth spectrum according to the growing stages and other conditions. All i can say iz that I plannig on to make 100% PAR efficient lamp, with 100000 hours life time (about 11 years) for a reasonable price with NO ANALOGS on the net! Cause I had had enough with HPS !!!

So please, do flood about light spectrum fotosinthetical curve for cannabis.
Thank you

Here is a chlorophyll activity by wavelngth chart in K rather than nm. (Spectra in bulbs are usually shown as K rather than nm)

Learn it. Live it. Love it.

PS... good luck with that!

light spectrum is 5000-6500K for veg

2100-2700K for flower

None of this is waht he's looking for. The good one posted is for generalized plants, ie not specific to cannabis.

i'll take a look around see what i find.
