I am trying to root some cuttings indoors. I have read everywhere that cuttings need "bright, indirect sunlight." I was wondering if it is necessary to provide some kind of supplemental lighting (i.e. from a grow light system) to provide this type of light. If so, what kind of supplemental lighting would be best for cuttings (i.e. metal halide, HPS, fluorescent, etc.)? Also, with regard to growing media, some sites recommend Styrofoam plugs, rockwool, etc. Will using these types of supports help at all with the success rate of rooting the cuttings? Or will a vermiculite/perlite mix work just as well?

A florescent light bulb set just a few inches from the cuttings will help to provide supplemental light. Here is more info: https://www.gardeningknowhow.com/houseplants/hpgen/fluorescent-lighting-for-indoor-gardening.htm
