Lovely looking VFTs, Tsmola. Look at the red flush on those beauties! Only problem I would probably guard against is lack of humidity, what with it being an indoor environment.
Last year, I had 4 VFTs that were growing in front of a large, south facing window which serviced them with direct sunlight throughout the day. They only really started thriving, though, when I put them in terrariums I made from 5-litre bottles you get mineral water in from the shop.
