Best Strains for Beginners




Z-Strain is part of the Psilocybe Cubensis Species and a common choice for beginners. This strain is said to be easier to cultivate, faster than others, and known to produce large "meaty" mushrooms. 




B+ is a well-known strain of hallucinogenic mushroom species. The B+ strain is popular with growers because it is easy to work with, accepting a very wide range of growing conditions and substrates and producing large, thick caps. 



Golden Teacher

Golden Teacher is a magic mushroom strain cultivated from Psilocybe Cubensis. Also known as GT shrooms, Golden Teacher was discovered in the 1980s and has since remained a top choice for many.
