I setup a simple windowsill terrarium for my kids in their bedroom window. *I built a small table and painted it to match the kid's rooms. *I then purchased a seed tray with humidity cover and drilled holes in it control heating. *All in all I think I was out about 15 bucks for the wood and seed tray and cover. *Here are some photos.
And with the cover on.
I've had it in this location for about a month and the plants seem to be thriving. *The VFT were brought our of dormancy a few weeks ago and are showing nice new growth. *They will be moved outside when the Colorado Winter breaks.
