Except for the price... Soilmaster and Turface are much cheaper. But if you cant get them locally, then the AP substrate might be an option.
so far I haven't had any luck finding either the Soilmaster or Turface anywhere in town. Still need to check Home Depot but all their plant/garden stuff is outside buried in snow..Anyone know if Walmart might have it,or someplace else I haven't thought of ? Don't think there is a Garden Center/Landscape place in town anymore
