Getting some unexpected high moisture reading with my harbor freight MM, 9 month CSS walnut mid 20's to mid 30's, Oak last fall read at 31%, mid 30's now. Mulberry CSS for 17 months reading mid 30's! These were all fresh splits, temp in the low 70's. I know the walnut will burn but I really wanted to use up the mulberry and get it out of my way. Would a solar kiln do any good for 2-3 months? Or just let it set another year?
