It didn’t occur to me the under canopy lighting would hamper vertical growth?
I’m definitely sold on using them, need to wait for the stretch before running them?
I’m running my Rapid led far red pucks, running 5 min, before- 10 min lights out. Should I cut back to 5-5 min.?

FAVEN answered back ur questions and info via email . Hope this helps?

Far red can increase stretching. We suggest using far red for 5 mins after the lights shut off.
We suggest starting far-red sometime between weeks 1 and 2 of flower. Although that is with our lights. I have no idea what the quality or strength of the pucks you are currently using are. It's hard to give advice on other companies' equipment. If you are interested in Favens, I would be happy to work you up a quote.
I hope you have a great day! Talk with you soon. “

I’ll adjust my Far red to 5 min. from 10.
I’d be curios what kind of quote you’d get?
If they were smart, you could pimp the shit out of them, he’ll you already are.
At this point, I’ll probably stick to the strips I have.

I can see I need to make mine adjustable, height wise.

Not sure what you are running for lights, 15 mins before and after is better than 10-5. With 10-5 you are not getting full benefits and your giving more of hint that day/night is coming.
Far-red light (around 730 nm) rapidly shifts the plant’s phytochrome system from the active form (Pfr) to the inactive form (Pr) etc

With 15 mins you’re getting much more complete phytochrome pool, stronger more consistent end/start of day signaling, it can enhance faster stomatal opening/closing timed earlier metabolic shift into day/night respiration phase and most of all more photoperiod perception which is important in short day plants like cannabis.

Phytochrome conversion isn’t instantaneous across all tissues. Leaves at different angles and canopy depths receive different photon flux. Longer exposure increases the total
Conversion ration.
So 15 minutes tends to produce a more uniform whole-plant response.
Past a certain point, you hit diminishing returns, once phytochrome is mostly converted, more far-red doesn’t keep adding benefit.

I don’t run my far red during lights on till around week 3-4 of flower as I find the signaling to shade leaves tend to be a bit much. Node spacing will be further apart etc, I run mine around what would be mid day upper and lower far red with upper uv far red for 2-3 hours and uv 1-2 in between the far red period and I slowing bring that time down week by week till until end of flower.
