Major steps towards better, sustainable and affordable food production free of environmental challenges have been taken, with the "world's first farm to grow indoor, vertically farmed berries at scale" opening in Richmond, VA. It's backed by an international team of scientists that see this new…
You realize that this picture addresses nothing of what I said? It’s using 15% when we can get 30%. And still has nothing about what spectrum the plants actually need of what touches them.
Edit: Also a quick search showed 2.9umol/j leds now, and maybe we have higher, so that’s up to 870 (3.5x more than image or 62.14% of the sun) hitting the plant now of exactly what it needs instead of 1400 that isn’t all what it needs.
Edit: another article from 2017 says the theoretical maximum for LEDs is 4.9-5.1 and we should reach 3.5 within a decade (2027). Also I think I didn’t understand the measurement and the 1400 from the sun is the 1400 it needs, but I’m not completely sure.
