From setup to harvest – everything you need to know about your Sproushi device and mushroom capsules
Instructions
[🕒] 1. Use Immediately
Best within 2–3 days of arrival.*
[🧴] 2. Sanitize
Clean workspace with alcohol.
Sterilize syringe tip with alcohol
[💉] 3. Inject
Insert syringe into the rectangular patch.
Inject 2–5 ml liquid culture.
Patch reseals automatically.
[🌱] 4. Colonize
Store at 20–24 °C (68–75 °F).
Wait until bag is fully white (~2–4 weeks).
[🍄] 5. Grow in Sproushi
Place fully colonized bag into your Sproushi and cut a cross with a sterile knife
*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.
Longer storage increases the risk of contamination or drying out.
Can I order multiple Capsules and stagger their use?
Yes — just be sure to plan your inoculations. Since Capsules should be used within a few days (or a week max in the fridge), you’ll want to inject each shortly after receiving them rather than storing long-term.
Can I use both liquid culture and spore syringes with Sproushi?
Yes ✅ Both work.
Liquid culture (LC): living mushroom starter in liquid form — faster, more reliable colonization.
Spore syringe: dormant spores — slower start, but still supported by Sproushi.
How does the process change if I start from spores?
Spores: need time to germinate first, so colonization takes longer.
Liquid culture: colonization starts immediately.
In both cases, once the Capsule is fully colonized, you cut it open and move it into Sproushi to fruit.
