These look like they are designed for the Emerson effect which can be used as a full time supplement, depending on the strain. All the reds will cause stretch. I have my 730 Far reds on a separate control from the 630s, 660s and 850s(IR). And Depending on the strain, I use the 630, 660, and 850 s, all day from the flip to 12/12 or I’ll start toward the end of the stretch If they are sativa that reach for the sky. With the 730s I start at the flip 5 minutes pre and post sunset. Then toward the end of stretch they are on all day With the other reds, plus the 5 post sunset.
Have you discerned any effect specific to 850nm? Will be testing some shortly
Hard to tell. Anything I could offer would be anecdotal. Mostly I threw them in there for leaf temp. I feel like I’m getting an effect from the 730s at sunset. I grew some sativas last run and they harvested very close to the breeders time schedule. So I feel like I shaved a week or two off. I kept them at 12/12 and was down to 10/14 by the end. Some guys bump up the daylight hours with the 730s at sunset. Haven’t tried that. Maybe this run. I also added Acadia 14% UVB so there were lots of variables last time.
Anything morphological? Stretch? Budstructure?
sounds very reasonable, and is a very interesting setup. how much power do you give to the 850? can you measure an increase in leaf surface temps when these are on?
How do you like the 132s ? What size is your grow and what are you using to drive them. I cant decide between the 132s or strips.
was just gona ask the same thing, how many watts of 850nm do you have per sq/ft and have you measured leaf temps with and without?.
I like them pretty well. They run a lot cooler than my 260's. I'm running on 2 hlg-240h-c1750 and 1 hlg-185-c1400. I have them in a 4x4
The reds definitely cause stretching and larger leaves. I have another channel that is UVA up to 465 blue that causes smaller leaves and shorter plants. At high power it can cause problems light stress and bud bleaching on some strains.
I’m at a watt per sq ft of 850s. 2 watts per sq ft of 730s.
I was refering to any morphological chhanges due to IR 850? We are trying roughly 70w over 2m2.
I just see all these lights coming with 660 built in and wonder if I am missing out on something. Not to mention all the supplement bars and pucks. There would be 48 730 chips in there, along with 144 660. Not sure how much is too much
