My HPS Bulb is out, I ordered a new one, but could take 5-7 "business days" aka 2 weeks. My ballast is switchable and I have a Metal Halide bulb in right now. Is this ok for 2 weeks or should I go to the hydro store and buy a bulb stat?
I think you'll be ok to wait until your new HPS bulb arrives. With the MH bulb its still kinda good; its not like you switched to a single incandescent bulb for a week.
