You have heard that fluorescent lights do wonders for your electric bill. Mine dropped by a third. Not only do they use less electricity than incandescent lights but they don’t throw the heat that incandescent lights do.
They also are wonderful for your house plants. We’ve noticed that house plants that are not doing so well will thrive when placed under a fluorescent table lamp. The lamps also do not heat up so they can be placed closer to plants that need a good dose of light.
I’ve found many low light plants will do just fine on a desktop with a bright fluorescent bulb.
A good rule of thumb is to use 20 watts of fluorescent light per square foot of plants.
