Hello! I'm new to the forum and have questions about the spiral fluorescents that many folks (including me) are using to replace their incandescent bulbs. I have a fairly dark house (we are surrounded by large trees) and am having problems with a corn plant that I think is suffering from a lack of light. Will placing the plant under one of these (I'm using 60W) help? If so, how many hours a day? Are these effective lights to use on other houseplants if lack of sunlight is a problem?

Also, if anyone reading this has any other ideas about why a the leaves of a corn plant would begin to turn yellow at the tips, then spread, then turn brown, (over-watering isn't the problem), I'd love to hear from you! (I hear that they like to be root-bound and this one is in a 16" pot, so it isn't... could that possibly be it??)
