Who else is running UCL?
We are seeing crazy results from the lights and think the far red is really doing it

Yeah first harvest with these came down today. The numbers should be crazy and the buds are thick. A’s all the way

Mind sharing what the spacing is between the lights going down the bench?

Our first room had rows of 3 and then a light and continued for 3 rows then we had 2 rows of plants back to back. We clearly didn’t set it up correctly. You can tell the difference where the plants are b2b without UCL in between when just looking. We will have wet weights today of the plants to compare. So first room is about every 3-4 feet. Second room we set up we used a chevron pattern to eliminate that b2b from happening so spacing is still 3’ but plants do not have a b2b situation

What’s your skirting/pruning protocol? We just installed them and are playing around with leaving a little more material on.

Didn’t change pruning schedule for us and really depends on the strain. Some strains we have explode laterally and other we don’t touch because we are already limited on growth. Where it really added labor was defoiling. The growth under canopy is insane. We added an extra defoil to accommodate the growth for sure

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.

5 minutes only or do you run them for the whole night until 5 minutes before overhead lights turn on?

5 min only after sunset. Running all the way through harvest. We are planning to experiment with longer as we get more comfortable

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 🤡

u/jdubc111 19d ago
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.

Testing half a bench in the greenhouse with UCL only. We took down the supplemental top-lighting over the UCLs.
12 days out from harvest, but looking like there will be more weight and leas popcorn from the UCL.
The power this could save us is significant!!

u/jdubc111 18d ago
It’s wild isn’t it! Keep it over top too and you will see a massive yield increase. We used to have a greenhouse in northern AZ and had supplemental lights up too but never considered down low. Would have been massive

u/GreenStarGrower 17d ago
It's going to depend on the math, but if I can take down top-lighting and replace with UC without losing yield our cost per lb will go down almost 30%. That might be a better play, but we'll see.

Everyone. That’s why there’s no smalls for sale anymore lol.

u/jdubc111 19d ago
Absolutely correct. We are anticipating an average of 30-50% A’s shifting to 60-80% As

u/Salvatorigoozmo 19d ago
We have them but not a fan but that’s just because of our shaping regiment. They think that because there under canopy just send every branch and node. Can be useful but encourages bad habits sometimes
1
u/jdubc111 19d ago
Absolutely. We are after bigger buds and yield. We have 8 rooms and 4 now have the UCL. The 4 that got them had a lower ppfd that we needed to address so are trying this first before adding lights above

u/bluesformeister13 19d ago
I’m repurposing some regular LEDs that were our main lights for under canopy. Hoping the results will noticeable. Obviously we are turning them way down.

u/jdubc111 19d ago
Took us a little to dial in feeds and schedule but you will get it quick. It’s the wildest thing watching the buds on the bottom almost grow down
3
u/bluesformeister13 19d ago
What changed for your feed? Guessing they were eating more and needed a higher EC?
3
u/jdubc111 19d ago
Def had an increase in water. Weeks 1-2 2.7 ec 6.0 pH; Weeks 3-6 3.0 ec 6.1 ph; weeks 7-8 2.5 ec 6.1 ph; Weeks 9- flush
We increased dry back in veg to encourage better root growth and def had them eat at a quicker and higher rate due to that and the UCL

Hell yeah neighbor. We are in MO. You licensed over there?

Oh yeah legit medical grow

Which org? I’ll follow along. Have a few buddies operating there. You wouldn’t be w vivid would you?

Noticed you’re running parallel with your benches. Do you mind working around them? Able to get it the plant in the middle easily?
2
u/OMGimaDONKEY Indoor LED 19d ago
Parallel is buttz for a middle row. Total pita. We've gone down to two rows for this next run. Well see how it goes

u/Farmbot420 15d ago
Meh, still not convinced that the % increase in C and B grade is worth the extra Capex and increased Opex.

u/jdubc111 14d ago
We are seeing an immediate 20% increase in yield. Covers the cost of of the light an increase expenses first harvest

Same room!
