Re: Mark's WFO
I did both. I made the lightest concrete mix I could. Then after I had gooped it the best I could I used sheet metal (old galvanized roofing) to contain the pour. I poured in the remaining bags of vermiculite over the whole works then covered the whole show with dirt ...Seems like I used about ten large bags or so.
