I was reading that “ In University of Maryland studies of indoor-grown cannabis, sativa with no UVB compared to plants provided with equatorial sun levels of 385 nm UVB had a 33 percent increase in THC levels.”. Further reading on several sites has me convinced that I should be adding UVB to my grow for the last 4 weeks of flowering to increase the number of trichomes. With that said, I’m clueless. This unit seems like a great deal ...can anyone comment on the spectrum or brand?

I’m supplementing a 1000watt HPS in a 5x5.
Can anyone comment on the brand or spectrum? It’s only 24 watts too....is that really sufficient?
