Wondering how your drainage is. We have problems in winter with greywater because of so much more water added via rainfall and melting snow. Might some need more gravel for percolating down? What about hitting ground water with the pipe? And could you show the greywater processing in the video? Are you using cattails or plants to help? Is there input and output? Does the output freeze? Or does it return to the ground water? If groundwater is at 10 feet could you build a mound?
What about gassed and fumes. Will there be a vent that could be opened?
Just a few questions. I definitely support the project! There is a house in Norway or Sweden that has greywater recycling. Greenhouse over house. But very high tech. Passive off grid important. If necessary you might be able to run a passive fan to vent?
Our greenhouse is passive and doesn’t freeze hard enough to kill the lemons since we insulated the back. In Oregon not Montana!
