Some of our users on the west coast of USA probably already know about a company called EB Stone. A local company carries many of their products but not their soils. Instead, they are packaged by EB Stone so they are basically the same formulas. Anywho, I was trying to figure out which soils where which (many are obvious) when I stumbled upon a new mix they did not have a few months ago: Recipe 420 Potting Soil The secret recipe grower formula for vital growth and optimum impact. The Emerald Triangle blend is a special blend of ingredients hand selected specifically for the needs of professional flower growers. Our 100% natural & organic formula is carefully crafted to provide the ideal conditions for cut flower production. Recipe 420 is a blend of premium aged fir bark, coir, sphagnum peat moss, pumice, earthworm castings, seabird guano, crab meal, and humic acids. Enhanced with mycorrhizal fungi and beneficial soil bacteria. Well, it would be an obvious market since EB Stone is based in California . Just thought it was pretty cool that someone is actually using such obvious hints to its purpose.
