Aren't those the two most important considerations we need to look at? |
Pretty much. I have been reading up on some of the more recent work being done to unravel cryptochrome/phytochrome interactions, so I understand far less about photomorphogenesis than was previously the case
. I do know that the photoreceptors have very low action and saturation energies. So reasonable B/R and R/FR ratios at low energies would seem to be sufficient.
Good PAR efficiency is better than bad PAR efficiency, but not all PAR watts are created equal. Poor Lumen is just a nice photon trapped in a bad neighborhood.
At least for now, I am kind of looking for something that lines up on chlorophylls. Delta paid some attention to the carotenoids, but I don't know how important that really is.
I have to spend more quality time with Tazawa.
