That sounds like a really good setup for keeping tropicals through the colder months. I especially like the idea of using the fan for constant air movement, since stagnant air can become such a problem in an enclosed space. Keeping the temperature stable probably makes a big difference too. I’ve been tempted to try something similar for plants that struggle on the windowsill once the temperatures start dropping.I’ve been using a 2x4 tent with an AC Infinity setup for houseplants during colder months, and it's worked great. The fan keeps air moving so I don’t run into mold issues, and the temp stays steady with a small heater and the built-in controller. I mostly grow tropicals and a few succulents, and everything seems happier inside than on the windowsill in winter.
