So there we were at at the Sinus Spectrum watching the kids and our spouses run wild, when my sister-in-law started inexplicably speaking my language. "Bryan thinks I'm crazy, but I want to build the kids a playhouse with a green roof." She pulls up a photo on her phone of a thriving green roof. The conversation rolled forward quickly as she got around to some even better buzzwords for me. "I really want to build a 10'x20' aquaponic greenhouse, and I want it to be completely off-grid." Now we're talking! So we started discussing details. She wants to start small with an aquaponic setup using a single IBC tote filled with veggies and tilapia and start expanding from there. When we got around to the off-grid portion, we discussed a solar water system for heating and solar electrical for cooling, and I remembered an older Treehugger article about building a greenhouse partially underground in order to insulate the space very well and to cut down the amount of building material (& $) needed.
All that is to say, for those of you contemplating building a greenhouse, here is that Treehugger article I mentioned:

May you start your own healthy and delicious underground revolution!
