Most indoor growers in Europe at least grow solely under HPS HIDs which have little to no UV output. Most indoor growers used to use MH which does have useable UV output levels.

I personally combine both HPS and MH with specific UVa and UVb tubes when running an indo' breeding programme.

I'm not looking for advice, I know what I think about it, I was wondering whether you guys had any views.
