Do you sell mushroom spores?

No.  But I have cultivated them in the past.  It’s been a few years since I was actively growing Psilocybe cubensis mushrooms (my current flat is not really suitable, and anyway here in lovely wet Scotland we get thousands of Semilanceata in the autumn). Never-the-less, I did have some success.

I got my spores from SmartBotanics^>>. 

The reference I followed is the Magic Mushroom Growers Guide^>>

For more detail see the article Growing Psychedelic Mushrooms^> in the 'Shrooms section.
