Fluorescent lighting can be used for growing. Color codes 21 or 33 (cool white) are especially useful during the vegetative stage.

The benefits of these lamps are that they are cheap. Also, they emit relatively low levels of heat so you can place them as close as a few inch from the plants.

On the downside, these lamps do not yield as well as HPS lights, LED lights and HPI lights.
