MyCO2 Grow Kits


Product Description

*****When ordering gifts for Christmas or for the holidays, earlier than December 11th, please make a note with your order. Mushroom kits need to be started within a month or so of when they are received, to ensure best production.  To mitigate this we will ship out all holiday orders the week of the 11th of December to ensure the kits are fresh and arrive on time.  Thank you and Happy Holidays!


Cascadia Mushrooms is proud to offer a new innovative product, the MyCO2 Grow kits from Fungivore Mushrooms!

This ingenious kit features a patent-pending design invented by mycologists at Fungivore Mushrooms and the kits are made in-house at Cascadia Mushrooms. The design enables the kit to be inoculated at home without opening the bag or needing any specialized equipment! 

Watch the mycelium grow from start to finish and grow Oyster or Reishi mushrooms. Great for classrooms or beginners to observe and study the growth of fungi. 

Originally designed for indoor plant gardening, the MyCO2 kit starts producing CO2 after spawn has been mixed with the substrate and slowly releases over several months supplying enough supplemental CO2 for a 4'x4' growing space per kit.

Choose the "Grow" kit for Shiitake mushrooms to achieve slow-released CO2, or the "Bloom" kit for Oyster mushrooms which release CO2 more rapidly.
