Ordered Drystall from Kruse Feed and Supply, La Habra, CA. Bought 40 lbs, cost about $84 delivered. I have had no problems with this product in the past growing succulents and cactus. I found another site, Rutsu Pumice Soil, cost about $74 delivered for 40lbs, and they are focused on growers, not pet owners, and have different size material unlike Drystall, so I will try that next time.
