Virtually no lamps produce UVB in the 280-320nm range due, in part, to the limitations of the glass. Solacure lamps are the sole exception as they use a type of glass designed specifically for transparency across the entire UVB spectrum.
This patented glass technology, combined with our unique blend of phosphors and high output, is what makes Solacure lamps the most effective producers of UVA and UVB light and the only lamps capable of triggering the full UVR8 effect.
HOW TO USE
The exact UVB exposure time will vary, but a good entry point is:
1. start with 2 hours a day split over 2 x 1hour intervals (within your light on period).
2. Increase exposure by 15mins every TWO days and check for signs of burning on leaf tips - this is when you've hit "critical mass" and find the sweet spot for the amount your plant can absorb
Note: The amount of UV will vary from 2 to 6 hours a day in grow tents and up to 12 hours in a bigger room.
