I'm wanting to leverage the Emerson Effect -- primarily to shorten flowering, but I wouldn't turn down increased yield as well. Perhaps it's my age-addled brain, but synthesizing all of the various processes and parts into the "right" solution leaves me with a lot confusion and questions.
If I understand correctly, synergy between the PS1 and PS2 processes seriously increases a plant's rate of photosynthesis if optimized with proper timing and intensity of EMR in the 660nm and 730nm wavelengths, but the 730nm can also be used at the end of lights-out for a short period of time to quickly transition to their dark cycle. Please feel free to add info or correct my misunderstanding.
My existing light uses 400 watts of 4000'K strips over a 2' x 4' scrog to put out about 1000 PPFD, and, according to the graph of the spectral output of those strips they are about 40% relative intensity at 660nm (though, I'm not sure what that means in PPFD) so a seemingly significant amount. Does that mean I only
need to add a commensurate amount of 730nm during lights-on to compliment the already existing 660nm in my strip light? If so, how many watts of 730nm should I add? Or, if I should be adding both 660nm and 730nm, how much of each?
As far as timing, from what I understand the 730 can be added to 660 throughout lights-on to improve yield, but also, should be left on for 10 minutes at lights-out to quickly transition the plant to their dark cycle. Again, corrections appreciated. If that's true, should I put the 730nm light source on a separate timer that comes on with my main lights, and off 10 minutes after the main lights are off? Here's my light:
It has 8 x EB-series Bridgelux strips and a 39w UV tube. I'm thinking about adding 2 strips that provide a low wattage of 730nm in the frame channels on either side of the UV tube to give good coverage, but all of the strips I've found that emit 730nm are like 20-30 watts. I'm a DIY guy so suggestions for 730 strips and appropriate drivers appreciated. Seems like a couple of strips that put out 730nm in the slots of my light frame on either side of the UV tube would give good coverage, but no idea as to the best source for hardware.
Regrets for the wall of text, but thanx for any help.
