CanvasCapsules contain a sterilized substrate without active mycelium, so even tiny contaminants can take hold.

By injecting your liquid culture right away, you give your mycelium a head start. Once it colonizes the bag, it will be strong enough to resist contamination.

FAQ

Do I need to cut the Capsule open once mushrooms start growing?

Yes ✂️ After colonization, when the substrate is fully white with mycelium, cut the bag open and then place the Capsule inside Sproushi.

👉 From that point forward, it behaves just like our pre-colonized Mushroom Capsules.

How soon do I need to use my CanvasCapsules?

For best results, inoculate within 2–3 days of arrival.

If you need to wait, keep them in the fridge (4–8 °C / 39–46 °F) for up to a week.
