Hi. I originally purchased all my WFO supplies a few weeks ago, bricks, insulation, mortar, vermiculite etc. After much thought (and many questions on this forum) I decided to lay vermiculite concrete under my calsium silicate board so I purchased some extra vermiculite from the local hydroponic supplier.
The vermiculite I purchased off him was grade 4 and the size of tiny marbles, the product I purchased a few weeks ago was grade 2 and much finer in size. I mixed the two together to make the concrete and it seems to have worked well.
My question is what grade (or partical size) should I use for the insulation around the dome once it is complete?
Cheers
Jase
