Dang!

I use a 400 watt MH-HPS fixture..after a while vegging under some T5s...I put some girls in a tent, and dang nabbit, I broke the metal halide bulb. It will be a week or so until I can get another one..in the meantime, can I use the bloom bulb (high pressure sodium light) for week or so and get good results?

Yes, you can use an HPS bulb for a full grow. Metal Halide is not recommended for a full grow, but HPS is fine.
