Sweet! Thanks for sharing!
Your plants definitely looked dialed! Keep up the great work!
I've used the UVB light from California Lightworks for several years. So interested in seeing your results. You should notice a difference pretty easily. They have some data at there site...
I tried 3 different schedules of various times usually no more than 3 hours on with very similar results.
