Succulent Indoor Lighting..
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.
Many people recommend using cool white fluorescent alone, or with a small incandescent. I think "grow lights" of many sorts do more for the manufacturers' pockets than for the plants. Of course, you can experiment all you want, remembering that different varieties of succulents have different light needs. Some people are beginning to use LED lights also - happy researching. Try to match your particular specie light requirements with light output of type of bulb.
I had success using regular cool white and warm white flourescent bulbs, one each in a two bulb fixture. The plants were 8" - 18" from the bulbs, depending on their needs.
