The flower powers in action.
These are on for approximately 10 minutes before the LED kicks in on the 12 hour cycle. Then running for 15 minutes at the start of every hour thereafter.

Loving my two Arcadia 46" 54W 14% UVB T5s. They fit (just) in my 4x4 tent and I can run them 14" above the plants for 12 hours a day with no issues. Haven't been running for long, but I'm super happy with the results:
Riddler OG at 4 weeks, and this isn't even the one with the most dandruff. First time I've ever seen frost this early (call me a noob)

Why do you do them when your main lights are off? Just curious, looking to learn.
I’ve got two Hlg uva supplemental bars and they turn on early/mid day.
From what I have read the highest of the UV is around 10am-noon outside.

I use two timers. They are difficult to synchronize exactly. The UV comes on for a short duration prior to the led. If you go to the Solar sure website and check out the grow power bulbs you'll see that there are different methods for utilizing them.

This is an update on my grow using a Timber Fatty with supplemental UV. I'm now in day 28 of flowering. The UV is used for 15 minutes at the start of every hour of the 12 hour light cycle. I'm seeing very little heat stress. For the last week I had the UV and grow light about 8 inches from the canopy. (just backed them off to 12 inches) Getting early trichome and terpene development. The plants did not develop as planned. I'm growing Bruce Banner (small plant) and Fruity Chronic Juice. I started the FCJ about 10 days after the BB. However, the FCJ went crazy and is overwhelming the BB. Ironic as the BB is mostly a Sativa and the FCJ 90% Indica. Overall the plants are looking very healthy with little stress indicators of any sort. Using Cultured Solutions. PPM 840, EC 1.2, Ph 5.9.

Yeah my plants are doing well. Best part is no powdered mildew.

Okay, so the results are in from this experiment.
Conclusion - At least for me, the results were mixed at best. The UV did not seem to make an appreciable difference in THC production and seemed to provide a slight enhancement to taste and smell. The overall yield did not seem to be impacted either.
The two strains I grew were Bruce Banner and Fruity Chronic Juice. According to various breeders the THC potential is as follows:
Bruce Banner 18 to 28%
Fruity Chronic 15 t0 22%
Test results were:
The results for the Bruce Banner were surprising. I've smoked both of these. The Bruce Banner definitely seems to make me feel higher than the Fruity Chronic even though there seems to be much more THC in the Fruity CJ.
It was a worthwhile experiment for my own curiosity. I'm going to give it another try with different strains. If those results are similar I will discontinue use.
I would say it's worth experimenting with UV if you're interested. Your results may differ. This was by no means a scientific experiment.

I like when people post pics like this about black dog led. All the negative comment magically go silent

So many bleached spots. The LEDs are probably not spread out enough?

just my 5 cents on the subject,
as this is my first run with uva and other supplemental lights, thought I may chime in. I run the uva as long as the main lights are on. Since this is the first time using them I cant compare to much other than, they've prayed the entire grow and seem to have been the happiest looking plants I've grown.
so this is what I have currently have as my supplementary source
100w(bloom enhancer)
LEDs: 64 Total
CREE XPE 660nm Deep Red LEDs
CREE XPE 450nm Royal Blue LEDs Heatsink
UV LEDs: LG
IR LEDs: Cree
100w UVa (385nm)
100w sleep initiator(730nm)
60w stick on leds(attach to sidewalls of tent to cover sides and bottoms)
as you can see, this cola is close to the lights. like 15cm. hasn't had much effect, but waiting to see for foxtails or bleaching.
here's the side lights I got from grow lights Australia, and the driver for them.

Yeah the bleached tops of every cola has so much bag appeal

I don't know it could be bleaching but if you look at the pic I just posted with that purple light some of mine look like they have bleached tips but when you take a pic with regular lights you can tell it's not. Could that possibly be the case here? Not my grow so I'm just assumingYeah the bleached tops of every cola has so much bag appeal

The light is way too close to the plants for sure but it was the first time I grow the strain and I wasn’t expecting like a 2 foot increase I’ve got some and veg that I’ll fix that problem next time but point taken for sure

I’ve seen people comment that the bleached tops often turn light-purple/pink after buds are dry. Any truth to this?Yeah the bleached tops of every cola has so much bag appeal

Not in my experience...they stayed white...was pretty cool looking on the plant and in the jar...only happened once on a blurple grow...northern lights...can't speak for what affect it had on the quality I never had anything tested but smoked perfectly fine.. taste, smell, n high
