I have been thinking about doing this! I have a few little gnats that get in from the garden. I'm pretty good about hunting them down, but I've thought that a carnivorous plant in my Aerogarden room would be a good idea! If you did this, perhaps I would join you! But I wonder if they like to share space? Maybe I should get a sprout and put them in that? What are you thinking?

Hmm! I could put them in just the water in a Sprout and feed them gnats?
That's what I plan to try, but I'm not sure how well it will work. Here is a thread from someone who has grown pitcher plants hydroponically, and here is a very short entry in the Carnivorous Plant FAQ about it.
