Frequently Asked Questions

All the ingredients are natural and do not give off CO2 emissions. These include mycelium, hemp hurd, wheat straw, clean sand, and biochar.

No, the wall that is tested is not alive. If you follow the instructions, heating the wall after its growth period will stop it. The heat shuts down the mycelium growth.

A study shows that mycelium insulation in a wall can increase the energy efficiency.

Most of the ingredients were bought from www.grow.bio

Currently, the mycelium wall in this project is only a working prototype. Hopefully, someday it will be available at national and local home supply retail locations.

Currently, the mycelium wall in this project is only a working prototype. Hopefully, we can get a finished product someday

Accelerated aging tests have not been conducted yet, but grow.bio says that if mycelium can last up to 30 years, if not subjected to harsh environmental factors, including exposure to moisture.

Currently, the working prototype is being tested for water resistance and will be tested for mold growth. Drywall is a high-mold growth material when it gets wet.

The cost of a single wall (12” wide x 12” long x 1/2” deep) was $13.45, however, scaling it up in future production and purchasing larger batch materials will decrease the cost per wall.

Yes, with the right tools, compressing the mycelium with a flat surface after its growth period and before heating it can do a good job smoothing the surface.

Currently, the testing of the working prototype is very positive when compared to drywall. Additional testing will be done to determine if it is a viable alternative to drywall.
