Can you combine a uv light with a hps or metal halide light?


#2

I use mh ( veg) & hps (flower) with cfl side lighting.


#3

I use the cfls on the sides of tent. Actually only use them in flower with hps at top of tent.

Sure you can just watch how close uv light is and how powerful the light is as well remember you cant see uv light and never look ar a uv directly with out eye protection
So some research on proper wavelengths as well

@Countryboyjvd1971 pointed out the biggest part of adding uv. Getting the right wavelengths, at the right intensity, for the right amount of time is key.

The Argomax bulbs seem to be about the only option I could see someone justifying to add. They provide uva and uvb, which is technically what has been shown to impact grows. But it’s hard to find data about how much to add. And more than a short period of time using them has caused more damage than helped. There are people that use them, but with mixed results.

Otherwise you’ll be looking at lec, and you may as well just grow with them.
