Still recovering from sickness this week. But I did get some work done on the experimental greenhouse. I’m insulating the north, east, west walls with 12″ of cellulose insulation. This is probably not cost effective in the final version, but for now it should eliminate problems of heat loss through these walls. I also framed in two fans for air exchange, 1000 cfm each, one exhausting air and one pushing in air.
