Yeah B+ is popular. It's a cube. Most cubes look the same beside the penis envy varieties and albinos. I mean if you grow them alot and different kinds you can see the slight differences. My favorite is a penis envy variety called melmac. I have 7 different clones of it I run, rustywhyte is another amazing one. White with rusty spores. (Cubes have purple black spores normally)
Ape (albino penis envy) that's strongest cube.
I also am growing psilocybin tampanensis. They grow stones more than mush.
I grow more boomers than I do bud, unfortunately. Lol
