The SolarSystem UVB light by California Lightworks is a great choice for anyone wanting to supplement their existing light with some UVB light for improved oil development and potency.

Get to Know the California Lightworks SolarSystem UVB Grow Light Bar

Note that this is a T5 fluorescent UVB tube, not an LED light. UVB LEDs are expensive, so all LED fixtures that feature UV light use UVA diodes, not UVB.

California Lightworks also offers a combination fixture with two UVB lights attached to their SolarSystem 1100 powerhouse light. The combination replaces the discontinued but hugely popular SolarStorm 880. You can find it here.

If you already have a regular SolarSystem 1100, you could also buy the UVB kit (select above directly beneath the price).

The UVB kit turns the 1100 into an 1100 UVB and can do the same for the SolarSystem 550, the SolarXtreme 500 and the SolarXtreme 1000 (lights are sold separately).

Features

  • Supplemental UVB 25-watt T5 fluorescent bulb

FAQs

What are fluorescent grow lights and how do they work for grow setups?

Fluorescent grow lights (like T5, T8, or CFLs) emit a broad-spectrum, low-heat light that’s ideal for seedlings, clones, and early veg. They’re energy-efficient for low-light needs and gentle enough to avoid stressing young plants.

How many fluorescent lights do I need for a 2x4 or 4x4 grow space?

For a 2x4, a 4-lamp T5 fixture is usually sufficient. For a 4x4, step up to an 8-lamp fixture or use multiple fixtures to cover the area evenly. Make sure PAR levels match your plant needs and stage of growth.

Wanting to get frosty?I was looking into the science behind uvb, ! I am very impressed! Result very between strains but the change is undeniable even my least frosty is now puking tricolmbs really would like them to be further away but height is an issue. I guess only thing left is sampling after cure . Thanks! Love Experimenting

I have only been using uvb for a week, 6hrs a day at 24�(recommended height)and so far I do not see a visible difference good or bad when compared to plants outside the coverage area. I have about 10days to go and will test after harvest hopefully there will be a higher THC lv in those ladys under uvb. I will update review when results are in.
