...the HPS (high pressure sodium)is designed to mimic the fall/harvest sun (red). The MH (metal halide) is designed to mimic the spring/veg sun (blue). They have HPS with a blue spectrum to use for all stages of growth....BUT, HPS will do all you need, just as the MH will......good luck.

Hps light's are the only lighting sytem's that are any good for indoor cultivation,a 250 will do a few plant's try to keep the light close to the top of the plant's.This will cause the plant to give close node's this inturn will then give you a far bigger yeild.I started with a 250 and alway's got anything from 4/5 ounce dry with a max of 4 plant's.I would advice you to flower small around a ft tall with the light kept close they will end up doubleing in height around the 2ft mark.But the answer to yr question is you have made the right choice with the hps light.One you get to grip's with growing indoor's move up too a 600.........tyke........

check your ballast if it can ignite mh. if yes , buy a mh bulb to use it in vegetative growth. the best and the simplest way.
i use fluorescent (6000k) for veg and hps (2000k) for flowering

...or better yet, get a digital ballest. They will operate a MH & HPS.

Or better than that, stay with your magnetic ballast and run a 250w Philips Ceramic Metal Halide for the entire grow.

to answer your question people VEG and FLOWER with hps , although as mentioned above hps is better for flower and Mh for veg.

Did you notice that light is designed for vertical applications only? That makes it a poor choice for most of us that use hoods.

That will be news for an awful lot of growers.

trichlone has just bought a ballast so will want to use what he has got.
You can buy a MH bulb compatible with your HPS ballast no problem.
