I’ve been checking out DIY Cheap Greenhouse to look for ideas to improve on the makeshift greenhouse that I build in my back yard. I like the height that his greenhouse has. A lot of this has to do with an idea that @creuzerm had to route the dryer vent into a greenhouse in the winter. Since we have 6 children and 2 adults in our house, we do a lot of laundry.
It would be interesting to see how this would pay off here in the Chicago area. Unfortunately the end of my dryer vent sits about 6 or 7 feet off the ground. It’s also a pretty far distance from where I have my greenhouse set up. Still I’d like to hope that there’s something that can be done to recapture the heat and water vapor from the dryer and put it to good use.
