That blast of red in the morning will help reverse the process too so they get started quicker in the morning. I actually overlap the FR for 5 minutes before lights off and run for 10 or 15 afterwards - now I can’t remember. Then in reverse in the am. It comes on 10 minutes before the mains and runs for 10 minutes afterwards.
Kinda simulates the morning sun and evening sun when the sun is low on the horizon and the atmosphere bends the light rays and gives that heavy red spectrum before it rises further and the angle changes and the rays straighten out.
I had a thread on it back before I bought the far red and got a lot of useful info.
There’s a lot of science behind the magick! LOL!
