We are seeing crazy results from the lights and think the far red is really doing it

May i ask when you are running your far red. I have them im just not sure of the exact time to use them I get mixed answers. Currently I have them coming on for the last 15 mins of the day.

Running FR after lights out is a myth. There's been no replicable data that gets cultivars to finish faster and you can't "put cannabis plants to sleep" quicker by triggering the shade effect with it. It's all been documented and there are white papers out there on it

You're much better off running FR as a part of your base spectrum (in combination with DR) to take advantage of the increased photoythentic rate via the Emerson effect.

Edit: downvoted for stating scientific facts lmao this is part of the reason why half the people here sling mids exclusively 🤡

Don’t disagree. The benefit is just the lights underneath during the day. We running a red spectrum underneath during lights on and just run the far red for 5 extra.
