I'm a newb here but have been following the procyon grow closely with anticipation.

I wanted to know if anybody has a chart of cannabis absorption spectrum? I have a general chart of absorption spectrum for plants but want to see a specific one for cannabis. I have searched for the last 6 hours and can't find one.

I have some engineering experience and from what i can see pretty much all the led grow lights currently for sale totally miss the necessary wavelengths necessary for optimal growth. Its really not that difficult to hit most of them except maybe the 660 which does not have a lot of good choices in the high lumen/watt range but there are plenty of blues to hit the target easily dead on.

If somebody can get me a chart of the cannabis absorption spectrum i would really appreciate it.
