African violets need a lot of light to bloom a lot. The light has to be bright, but direct sun will burn the leaves. Ideally, African violets need 12-14 hours of light a day. Let’s have a look at some of the possible lighting options:
1) A window that is bright but not sunny. To ensure symmetrical growth, turn the violets regularly.
2) A sunny, but not hot, window with a sheer curtain diffusing the light. As with option 1, to ensure symmetrical growth, turn the violets regularly.
3) Fluorescent lamps:
• 3a. Long classroom-style lamps. Turning the plants is not necessary for ensuring symmetry when using lamps above your violets.
• 3b. CFL lamps (energy saving light bulbs from your local supermarket). This is a good affordable option for supplementing insufficient window light (eg if your window is not bright enough in winter). Get a couple of light bulbs – one in cool daylight, another in warm white.
4) LED lights. I personally never used specialty LED growing lamps, so can’t offer much advice on those at this point. However, I have been successfully using white LED strip lights on part of my collection.
