I've recently had some good results with a mix of sunleaves coco coir, perlite, and wormcastings
I've been thinking about making my own mix, you can't get much good soil around here that doesn't cost an arm or a leg. I also don't know where I'd get coco coir locally, and I'm not crazy about ordering online. What do you think of sphagenum (SP) peat moss instead, and worm castings and pearlite? Would that be a good starting point for a mix?
