SolarSystem UVB

I used this UVB light three times during the grow, but the manufacturer instructions are tailored toward photoperiods. Three 15-minute sessions caused severe damage to the sativas growing in the same tent, so I'll probably start with 1-3 minute sessions during the next grow and increase from there. The indica-leaning and hybrid plants still showed signs of stress, but they recovered pretty quickly.

The tent always smelled extra loud after this was on. The research behind it also speaks for itself.

Great light for the size of grow (3x3 tent). Of course, if I had more to spend I would buy the next one up in their line. Great company!
