Hi there. I need 660 nm red light for plant growth. I don't have any experience with electronics but I have the following setup from my research on the internet:
Why is full spectrum needed when chlorophyll only absorbs red and blue light? It is a waste of energy to feed a plant photos that it cannot absorb.for plants you need the full spectrum LEDs.
Because "herbs" don't grow fast indoors in the winter without supplemental - these are the cheapest option but nobody knows how to connect them - so they post here.Why are there so many threads about this same grow light??
Some use 100W LEDs, some use 10W LEDs, some LEDs are red and other LEDs are full spectrum.
