Best Mycology Supplier out there hands down. Everything about this guy and his brand is just diamond tier. From his extremely and ridiculously high quality products… to the fact he makes it all and does all the labor himself by his hand ensuring that everything is done in front of a flowhood with sterile techniques being applied and also using only lab grade equipment to create his mycology supply products.
Quick delivery and so far product working well. Promoting fast growth.
