California Lightworks SolarSystem UVB Kit
The SolarSystem UVB kit from California Lightworks can boost the effect of the grow light system it attaches to with its 2 SolarSystem UVB units containing UVB T5 fluorescent bulbs. This system can work with a single light in a single home grow tent or hundreds of lights in a commercial grow operation. The T5 fluorescent bulbs produce the highest intensity light at the greatest intensity with very little heat, making it the perfect option for indoor operations.
The SolarSystem UVB features the latest generation of high output and efficient T5 fluorescent bulbs. These bulbs can massively reduce energy consumption while saving you from massive cooling bills thanks to their ability to produce very little heat.

UVB is measured in µW/cm 2 or microwatts per centimeter squared. Over a 4' x 4' area with the SS-UVB hung at 3' you're going to get about 90 µW/cm2 in the center, 35-50 µW/cm2 on the outside edges, and 20 µW/cm2 in the corners. This distance allows for longer exposure times (depending on plant genetics) with less chance of negative effects on your plants. 3 ft is also the ideal hanging height for the best possible uniformity. The graphic below shows UVB measurements over a 4' x 4' area with the SS-UVB hung at 3'.
The SS-UVB is designed to be used during the last 2-3 weeks before harvest when it can make a noticeable impact on plants. It is suggested to run your SS-UVB for 2-6 hours per day at 36" above the plant. If you're unable to mount the light at 36" above your plants, decrease the amount of exposure time. Do not power your SS-UVB on during your dark period as this can cause unwanted effects. Always monitor your plants to make sure you are getting the desired response, while making any necessary adjustments in height and/or on time to increase or decrease UVB exposure as desired. Growers typically see a noticeable difference in the number of trichomes within the first two days after running the SS-UVB for just a few hours per day. Many growers also notice leaves changing color in response to UVB exposure.
The SS-UVB covers a 4' x 4' area at 3' above the canopy. It is recommended that you mount the SS-UVB at this height. Different plants with unique genetics will respond differently to the intense UVB light that this fixture puts out. If you notice leaves on your plants start to turn brown around the edges, increase the distance between the UVB and your plant or decrease the exposure time per day. If you don't notice any unwanted results, you may gradually move the light closer to your plants or increase exposure time at your discretion.
