Spectrum

Intensity

UVB is measured in µW/cm2 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 best possible uniformity. The graphic below shows UVB measurements over a 4′ x 4′ area with the SS-UVB hung at 3′.

 

 

Hanging Height

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. When growing cannabis, sativa dominant strains typically have a higher tolerance to intense UVB than strains that are indica dominant. 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.

 

 

Timing

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 amount 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.
