I'm not sure. I've been cautious of growing my own starter because of the risk of contamination of salmonella and other fungus. Instead, I buy a large quantity of the Raprima brand of tempeh starter, and have it shipped from Indonesia. It ends up being about $30 for 500g of starter, which is enough for over a hundred batches of tempeh.
