yeah from what i have seen with the powerful reptile lights people only have them on for an hour or so at sun up and sundown, or in the middle, but not all day. Glad to hear yours is working out, where did you get it?
I usually use some CMH light on all my plants during flowering if the light is free. The bulb i have is not shielded so it does emit the uv spectrum as well.
a word of caution though, when dealing with any non-shielded light that lets uv out, WEAR GLASSES. protect your eyes you only have one set.
Here is a thread i made a while back noting my experience with the UV from cmh lights. https://www.rollitup.org/indoor-growing/384882-caution-cmh-ceramic-metal-halide.html
thnx for the uv heads up but i dont use mh only hps and i do know the dangers of uv spectrums check my laser bong smoking thread lol
