Good idea for a thread!
Ocean Forrest potting mix,
FoxFarm Soil & Fertilizer Company
Grows plants great, I think it has mites some times but that's just me. It now comes 2 different ways, from the west coast and the east coast. The west coast is the stuff we are all used to and the east is a new mix that is lighter and contains cedar. Have not tried the new personally but know people that like it just as good as the old mix. I am not a huge fan of FF products personally, but the soils work good.
