OK. I have some plants under a two, 150 watt bulb, halogen fixture, and some sarracenia under a 300 watt bulb halogen fixture. Is this good. I think I may start using flourecent lights. I'd probably use theese $5.00, 40 watt, 2200 lumen sunlight bulbs. I should probably use four for a variety of carnivorous plants right? Thanks a bunch. Also, the halogen bulbs aren't specifically meant for plants. Should I be using specialized bulbs?
