Grow Light Bulb?

Im growing a plant under a single bulb and interested in which grow bulb would do best for a standard room fixture. Plan on sitting it a few inches away from plant. At the moment its under a 75 watt forescent spiral bulb.

Cfl are they way to go in your just wanting to use in standard sockets

you should get one of thoses Y adapter that splits a single light socket into two just by screwing it in, and easy way and cheap way to get sum extra light with out more fixtures. they only cost a buck or two at the hardware store.
