so, I found a source for vermiculite, but it was very expensive and there were only 2 bags left. By my calculations, to make Mel's mix for my boxes I would need about 6 times that many bags and even if they had them there's no way I could afford it.

so, to finish filling my boxes, I have unlimited free compost, and plenty of peat. Since I'm using very very little vermiculite, should I also reduce the amount of peat that I use? Or still do equal amounts of peat and compost?
