Sure. You can grow plants in many different kinds of light as long as you have enough light. For example, incandescent light is considered inefficient for human eyes, but it is not too bad for plants.

People used to think those purple LEDs are efficient, but that is an old thinking. Top-end white grow light is as efficient now in terms of plant photosynthesis (and can be cheaper).
