Another nit.

"To grow plants however, you need a total lumen count to reach the plant for photosynthesis. Plants use that in a 1% efficient process to convert it to various forms of energy. So, you can see that being off for 70% of the time pushes only 30% of the lumens (photons) to the growth process."

Plants, like eyes, are running at chemical time scales. They mostly care about the total number of photons they get, not whether they're spread out over a 120th of a second half-cycle of a powerline frequency or concentrated into 30% of it.

I have a number of small, commercial, hydroponic planters where the tomatoes and bell peppers are doing just fine with no light input except the (rapidly flickering, off much of the cycle) fluorescent lighting.
