Hello, I am curious.. are their any ballast/fixtures available that would allow me to switch out a Metal Halide light for a High Pressure Sodium light? It'd be great if I didnt have to switch out the fixture between veg/flowering cycles. I use the Halide for Veg and the HPS for Flowering. ~Experimentalist
I know if you get a hps ballast you can put a cmh bulb in it for vegging and then the hps for flowering with a single ballast. Thats what I would do if I were you.
MH and HPS both have the same socket, if you get a standard HPS ballast, all you need is a conversion bulb, and you can run both. If you buy/bought a digital ballast, it can run both types of bulb without a conversion bulb.
