B+ Grow Kit 1200 ml – GetMagic® | Magic Mushroom Kit

About the B+ strain

The B+ psilocybe cubensis is one of the most popular strains in home cultivation. Its exact origin is debated — most likely a US-bred cultivar that has been refined over decades for reliable indoor growing.

B+ mushrooms are recognised by their thick stems (40–120 mm) and broad, caramel-coloured caps (30–80 mm) that mature to a rich golden-brown. The strain bruises blue-green when touched and produces dense, heavy fruiting bodies across multiple flushes.

The experience is typically warm and euphoric: uplifting, mildly visual, and with a social, easygoing quality. B+ is often recommended as an all-round strain — potent enough for experienced users yet forgiving enough for a first grow.
