The Emerson effect is by its own means a growth acceleration ! What actually the Emerson effect tells you is that there are to photo systems working at red bands. The one works with the red band and the other with the far red band but when those two photo systems working together at the right ratio you can achieve 10 - 14 % higher photosynthesis rate. Most of the lights have a little far red output so you are basically recreating the Emerson effect but not at its perfect. As far as i remember the perfect ratio is R/FR 10/8 but i am not sure for that. Another way to use the far red since you have autos and you don't want to initiate the flowering is to achieve higher photosynthesis by making longer day times without effecting the regeneration rates at night time ( despite the fact that some growers have a 24/24 cycle at autos ). When you have a far red light open after the regular lights close the plant gets to the night time regeneration mode much faster so you can wake it up earlier. So for example if you were making a 20/8 light cycle you will be able to have a 21/3 or maybe 22/2 light cycle without disturbing the night time regeneration mode. That is 1-2 hours more photosynthesis. You do it by setting the far red light to open for 15 minutes after the lights close and for 15 minutes before the lights open again...I have never used them but i would definitely give it a try ! Happy growing ! 👊
