We're going to build a sm. two tier planter retaining wall using EP Henry Coventry Garden wall stone (link below) and was hoping for some help from you experts. The highest point will be ~ 18". How much 21A should we use as the base? What else will we need for the project?

I figure you mean how much depth of granular you will need. Typically 8" is good, but soil conditions and ground disturbance are a couple of factors that could be important to consider.
