Using Far red lights at lights out

[MiGrampa]

Thank you for this insight!
I'm using dedicated IR and UVA bars for the first time this run, and was wondering myself if the UV would negate some stretch from the IR. I have the same time settings you have for both. Thanks for sharing

I'm using 440nm (I believe) blues to fight stretch. I could add UVA and UVB. However I already have a lot of extra lights in there and the plants are currently in there too. I might have to add the UVA and UVB back for next run if I have enough information stating that the UV light fights the stretch.

It would make sense.......think tug of war between the photosynthetic spectrums.....and their respective growth patterns.

Anyone using 280-350nm Wavelength on buds last week here?

That's what I wanna see, I've just not been able to play with it my self yet.

Detrimental when used incorrectly, but I bet if it's used just right in the right way, it will/can increase the cannabinoid production



And eventually i will, I'm just in a fucked spot in life atm.

@Driver77 how many of the addlites are you using with your FC8000.
I run 2@ FC8000 that I cut in half to make them 2X8 instead of 4x4.
Nice first post~! Welcome to Bud Builders glad to have ya~!

Are you saying the UVA keeps plant shorter and helps fight the stretching with the reds?. Too much stretching is what limits the amount of red I do use. There's no way I can run them from 1 week - 3 weeks in flower. I don't have enough tent for that.. I find 15 min at lights out ample and 1 week is long enough. Then from 4 weeks on they can be on every night, stretching is done so I'm good to go.

I just transplanted and hooked up my Autopots and they've just started to feed from the trays and have jumped in color and overall health in the last 2 days. I added the reds for just 15 min last night and I swear they look better again today. I think I see through rose colored glasses after using them for just15 min again. I'm really impressed by how much a small amount of far red effects the plants growth.

Yes...uva will keep plants shorter. Great for countering the ir stretch.....to a point. Plus you gain the added perks of terps and potency although the potency part is yet to be proven in a study.

It's my understanding that UVB between 280nm and 310nm is what causes a stress response to the ultra violet radiation. I do have the CLW UVB fixture. I used it for a few runs and didn't notice any differences. I have not run them with 660nm deep reds and 730nm far reds. Somewhere I likely have a black light fixture for some UVA. I'm currently using 440nm blues to induce stockiness in my plants.

I have them all now. I've had the old style uva/ir bars that couldn't be timed independently for a few years and played with them quite a bit. The new 660nm red bars are new to me along with the blue for veg. I've got all 3 ir/red/uva running in flower for the first time now so we'll see how much it adds. The uva and ir are great by themselves though.....I'm convinced it gets a little closer to mimic nature and helps bring more of the genetics potential out.

Well, I'm glad you're here! .... we can all compare what we have going in this thread. I'm pretty sure @Pipecarver would be interested in our results.

It does and can be used for a much shorter duration to get effects. uva will give the same effects without the potential for damage. It's not going to make a huge difference if you are already maxing out a plants genetics....but I feel it does allow for that extra little something that otherwise wouldn't come out. There needs to be more scientific testing done.

I agree with that ... our testing will mean something even if its not super well organized and published in a scientific journal.

 

[Driver77]

Awful lot of fun "testing" too.

 

[MiGrampa]

I have 9 in a 5 x 5. I'm running 3 each (from left to right) Gorilla Roadkill Skunk (Skunk Really Works), Dante's Inferno tester seeds (GPS), and LemonGrass (Humboldt Seed Company). I plan on flipping to 12/12 on Saturday 3/1/25.

 

[Driver77]

I haven't got to play with the blue yet...notice anything yet?
I've got 2 Purple cream Edit: (front) 2 Glue Sniffer(rear) a week into flower in a 4x4 with the extra red running along with uva and ir. Different cultivars react differently for sure....

makes sense....its still BLUE light lol.

A nice green and healthy looking leaves, you're doing something right....eh, You're going to run out of boat, you'll need a bigger ship to flower those things. I see some pinching and bending in your future

Yeah...I flipped them early I thought. One of the problems with running different cultivars in the same tent. You'd think I would learn There getting the ole folded stem tomorrow when lights come on.
Thanks again for leading me here!
The knowledge on hydroponics on here is amazing. I've been reading for a couple hours a day and have done some tweaking with knowledge gained.

 

[Driver77]

The ir for wake up and sleep has made a difference in how they look at lights out and lights on. They used to droop an hour or 2 before lights out and after lights on and don't now. I didn't get it set up till just before flip so I'm anxious to try it in veg to see if it still holds. I used to just turn the uv and ir on for a few hours a day together(had the old style) and then played with separating them after buying a second set. I think it helps with bud density too.....anxious to see what others have noticed.
We'll see how yield does with the new red supplements that run with mains.....it's too hard to tell if I have more bud sites since I haven't grown these before. But I know what kind of yields I've been getting out of it to compare.

Drooping before lights out is normal, they all do it. Its funny you mentioned that I just posted 2 pics of them doing just that. They are much prettier in the am

@Driver77 - Actually, the over-all knowledge on this board is through the roof. We don't have an over-abundance of newer growers. The core of this group came from another well known forum. There was some friction and some people left and set up this group. Every one of us who are members here have been kicked/banned from the other group simply because we joined this one. So, long story short ... we have a lot of advanced level growers who have honed their skills through many years and many grows. In this sense, I believe you will fit right in.

I look forward to getting to know you on this forum.
