A 600w HPS emits 1100uE on PAR. Still taking into account optical losses about 25%, still there is more than 800uE avalaible to plants.

Still accounting the enhanced photosynthesis by spectrum, it can perform as 1/3 of a 600w HPS.

So depending on the bins the procyon use, it can perform as a 250w HPS, luckily.

BTW, its not difficult at all doing it yourself.

Good info there!

IMO you failed to mention a variable that favors LEDs.
Think "inverse square law"

Mahalo for the rep., brah.
