An extremely popular strain thought to have been developed intentionally by a cultivator twenty to thirty years ago—some people suspect it of being a hybrid between P. cubensis and another species, P. azurescens, rather than a pure P. cubensis strain. The fruiting bodies are relatively large, and the spores are quick to germinate. The strain is relatively easy to grow and produces a big first flush but smaller subsequent flushes.

Users report a middle-of-the road experience and a lethargic feeling, but nausea seems less common with B+ than with other strains.
