I have insulation below grade and on the bottom… I’ll still put in an air exchanger on the exterior wall… thanks for checking it out! I too can’t wait till your 1.5!! Should be growing SPS by thenI'm surprised to see it not get any insulation. Also humidity control is going to be insane. Super build. Best of luck. Cant wait to see the 1.5 yr mark.
good point, I was thinking black but blue may be better, hope to have it covered in coraline over timeThat will look great. Keeping the blue look so it blends in?
