This next text is a copy paste from my ig, I got to writing and felt this should be shared here too, or really here more than there but i typed it there first so whatever. Lol.
Closer look at some trichomes on sp250 side..
I noticed the trichomes on the sp250 side get a lil mo amber a lil earlier than under the sf4000. I think this 2 has to do with the uvb in the sp250s. My educated guess from this side by side is that the sf4000 will yield more and the sp250s will be slightly higher quality. The addition of the uvb makes for slighly more resin, but since we have both sides on equal wattage the percent of the light that is uvb is the same percent more that the sf4000 side will be putting into bulk. While substituting a lil quality for quantity may seem like the way to go, my research tells me that uvb isnt needed for the whole flowering cycle or whole lights on, so it might be more efficient to get separate uvb bulbs to run for 2 hour intervals during only the last 2 weeks of flower and produce higher quality without loosing quantity. Of course this takes away from the ease of a single light producing these results, if I were a light manufacturer I would try to come up with uvb diodes with independent controller/timer that can be switched on only during the needed time to save power and produce optimum results. That said both these lights are doin better than I thought and I dont see myself ever going back to hps lighting. .
Anyway thats my 7 week assessment, will see how this finishes out, they are on a diet of bat guano n a lil chitosan for for the next week then a week of straight water.
Heres a good thread on some uvb, a lot of bs in it too and opinions but some good info too for anyone interested.

N heres a lil side by side with the lights off...
