In February I set up a terrarium and planted it with mostly carnivorous plants and tuberous gesneriads. As time passed the CPs languished, and some died. The venus flytraps were sulking so I moved them outside to the bog bed where they now enjoy full sun. The gesneriads all showed signs of insufficient light, too. I was completely ignorant of the fact that fluorescent bulbs lose potency over time. But I read up on the subject this weekend. My old bulb was 15 years old and sooo weak! I bought a new bulb today, and wow what a difference! The light is much brighter, and the terrarium already looks so much better. The Pinguicula caerulea flowers seem to glow now. I really can't get over how much nicer everything looks! Hopefully its enough to make all the plants happy. Dennis in Cincinnati
