UVB lights.

I havent had a chance to use them yet but one of the bulbs is very loose on one end where the end cap is connected but still lights up. It is a little concerning safety wise though. Also shortly after delivery Fed Ex sent me bill for $ 98.00 .

USB KIT

I chose to hang the two USB lights on each side separate from the Solarxtreme 500 in my 3x3 tent to get them as high as possible. The SE 500 is 18" from the majority of the canopy. The USB lights are 20" from 6 tops and 24" to 26" above the rest.
I started them one day before week 6 of flower at only two 10min exposures and worked up to six 10min on and 20min off times over the next five days. In the middle of the 12/12 cycle for a total of 60min exposure.
Next I changed to 15min on/30min off for a total of 90min exposure for one day. Then added two more 15min times for a total of 120min=2hrs. The next day.
They have shown a huge increase in trichrome production starting after only a few days of exposure! I am planning to change once more to 20min on 40min off for six cycles= Still 2hr total.
I highly recommend these, very glad I decided to go for it! This is my first grow so I have been extra cautious using these with the incredible results I was already getting with the SE500. But the UVB lights have showered my girls with Diamonds!!!
Thanks California Lightworks!!!

What can I say. It does exactly what it supposed to do. I’ve never had so many oils on my plants before. Highly Recommended

I am three weeks out from actually using the UVB lights, but i have installed them. All the installation hardware was available to use. However I chose to hang mine separately from the LED lighting fixture. The only issue I have had at this time is that one of four electrical interconnections did not fit properly. I have emailed David asking for a replacement. David has always been very responsive and extremally helpful assisting with answering any questions and expediting a warranty repair. I am very satisfied with California Lightworks customer support and their products. Can not wait to turn these new fixtures on and see the results that everyone is talking about.

SolarXtreme 1000 w/UVB

Bought 3 SolarXtreme 1000's with the UVB's for each and I don't think I'll have enough space to type all of the wonderful words I have for these lights. I am completely blown away with the health and progress of my plants in my 5 x 9 tent. I'm so amazed at what these lights are doing for my plants that I'm thinking of ditching the tent and going to a complete man cave renovation that'll house nothing but top shelf cannabis growing under the CL product line. Since starting my UVB's a week ago, the smell in my tent went from sweet n stinky straight to STANK IN YO FACE!!! Seriously though, I've had nothing but great compliments on the set up and have even talked a few if my growmie into switching from HPS to the CL line. Thanks guys. Next up....a video for a shot at featured grower of the month!

Unrivaled harvest....

Thank you so much for the wonderful products you have made. With so many poor choices out there that are right alongside good one's I am grateful for discovering you guys. I own a Solar Extreme 1000 with the UVB kit (2) in a 5x5 tent, two Solar Extreme 250's w/a single UVB in a 2x5 closet. Currently the closet is in the last 2 weeks or so of flower and the tent just flipped to flower May 15th. I tried out the UVB on my last closet run and was so blown away by the results that I decided to ramp things up a bit and go with the tent. Super excited for this next harvest. Down the road I will eventually build an indoor grow op that will showcase your innovation. Once again I can't thank you guys enough. Photos are of my favorite strains that I have ran a bunch but this round was with UVB and Overdrive (Advanced Nutrients)

Have them installed….

In a couple of weeks it will be time. Will post then. As a note, the kit was short on plastic rivets. Had to repurpose used ones. You’d think you would get more..

UVB Kit - Sweet Stank to Total Dank

UVB Kit added to CLW SS550, no install issues. Started week 7, it has been 8 days in use. It is now running a 3hr cycle during the “middle of my 12/12” light cycle. In those 8 days the sweet smell now has an added a cat urine / skunk smell that is quite the noticeable difference. The SS550 already has already created tremendous trichome production like I have never seen before and the heads appear to be getting “bigger” since the UVB was added. Viewed before and after with a scope. Minimum, it is more than obvious to the nose that the Terpenes have been affected in a most wonderful manner. I cannot wait to try a blue only during flush.
