Why Choose Our Magic Mushroom Grow Bags

All our products are expertly designed to help you grow your own fungi microcosm and enjoy the numerous health benefits of these miraculous organisms. Our mushroom grow bags are:


✓ Perfectly Hand-Packed

Most vendors mix the grain spawn and compost to create a more homogenous environment, but we don’t play by the rules - we specifically hand-pack all ingredients to make sure they don’t mix, to facilitate faster colonization and to make it easy for you to monitor your culture as it grows.


✓ Fully Sealed and Sterilized

When buying our all-in-one grow bags, you get a no-contamination guarantee! We take all necessary precautions to prevent any nasty contaminants from ruining your culture, including sterilizing and fully sealing the substrate. Of course, damage can happen during delivery - if you notice anything strange before opening your grow kit, contact us and we’ll sort out a replacement.


✓ Made Using Only Highest Quality Ingredients

Our food-grade ingredients are all prepared in-house, so we can make sure each bag matches our standards of quality. We pride ourselves on only using locally sourced, organic ingredients, doing our part in protecting our beautiful planet and all its life forms.

Using Uncle Ben's Tek has its pros, however, most people find that the cons are not worth it. It usually involves a much more complex process which leads to a higher risk of contamination and longer cultivation time. Also, when you inject spores or liquid culture into your bag, this leaves a small hole that increases the risk of contamination. Our mushroom grow bags are the top choice product for a smooth growing process with minimal chance of failure. The bags are perfectly sealed and sterilized specifically to avoid the issues people have with Uncle Ben's Tek. Not only that, but they come with a self-healing injection port to fully reduce any contamination risk.
