I know that the biggest problem with growing a VFT indoors is the dormancy period, or lack thereof, and I am trying to figure out a way to do it successfully, so I figured I'd run something past the experts here. How do you think it would work if I put the plants next to a window and cracked the window? I live in Minnesota so it gets pretty cold here and hopefully with the window just barely open the cold would come in a little. I can monitor the temperature of the plants with a thermometer to make sure they get into the proper range. Any and all input would be appreciated.
