Makes your 'girls' PUMP 'sunscreen'

2nd verified purchase. 1st set is in a 5x5 this set is split between 2 different 4x4's. (Hung vertically in grotent corner to cover the whole crop from lolipopped bottom to top).

This isn't 'complicated' (even tho it is #science). It's 'simple'. The cannabis plant is the only flower on the 3rd Rock from the sun that can shield itself from (otherwise harmful UVB) by producing MORE 'sunscreen'; terps/THC.

Result? Bigger harder nugs. Increased THC. Happier 'farmer'.

If you've invested in CLW lites (or an offshore mfgs), don't be pennywise and pound foolish' and leave out a potentila 20%+ bump in THC ('sunscreen) becuase you didn't want to spend anothe Ben Franklin, or two. #justsaying STP

Love it

I absolutely love my uvb kit and if your on the fence about getting it don't be just buy it lol I'm not a robot either a real dude with a real review another thing to keep in mind the uvb that is made in led form hardly reads on a par meter you should watch the YouTube videos on the subject makes perfect sense

Amazing

The moment I turned these bad boys on the last two weeks of flowering my buds just became covered in trichomes. Hang these bad boys 3 ft above and get a repeat cycle timer and run it for 10 mins on 50 mins off for the first week then up it to 12.5 min on 47.5 off. I promise you won’t regret the purchase..

Well, I’m still waiting to use it…

So I bought this kit hoping to use it on the last few weeks of my grow. I received the first kit and everything was packaged nicely, however the lights would flicker and never turn on fully. Contacted customer support, everything went smoothly until I got the new kit. I sent everything back that I was sent (including the mounting bracket) and when I received my new UVB kit, it didn’t come with a mounting bracket to attach to my SE500. Now I’m stuck waiting to use the kit unfortunately…

Beautiful finish!!

I only have great things to say of the 1,100 and the uvb add ons. Vigorous growth throughout veg and bloom with the 1,100. To see the flowers at the end benefit from the uvb is almost magic!!!! I’m only a few days from harvesting our first indoor Virginia grow and cannot wait until curing. Thank you California Light Works your hard work makes our work easier!!

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 .
