I have read that Metal Halide and or High Pressure Sodium lights will benefit the needs of succulents. Looking at the 400 watt MH or HPS light fixtures, I see they are sold with both HP and HPS bulbs.
Question is - Do growers that use MH or HPS simply change the bulbs in the fixture and, if so, how often and when? Is their anyone out there using this lighting? Thank you.
