Can you use a grow light without a ballast?

In short: ballasts power the light bulbs. Grow lamps are low-resistance devices when they are burning, but they need a high voltage to get started. Without the ballast to regulate the amount of electricity going into the bulb, the light would continue to increase in intensity until the bulb blows.

How much power does a ballast consume?

They consume eight to 10 watts when operating with the lamp in the circuit. The ballast will consume about four watts when the lamps are removed although the ballast is still energized. Electronic ballasts start and regulate fluorescent lamps with the use of electronic components.

Can I use a MH bulb for flowering?

Due to the lack of red wavelengths in their spectrum, MH lights are not good at flowering plants on their own, though. This is the reason growers will use MH bulbs for vegging and HPS bulbs for flowering. Or even better, they use both bulbs simultaneously, for a much more complete spectrum.
