We’re a fully registered, full-time company that’s been lovingly crafting mushroom substrate for over 8 years — so yeah, we know our fungi!
Organic rye grain – because your mushrooms deserve that organic lifestyle.
Medical-grade self-healing injection port – it’s sterile, it’s rubbery, it’s basically magic.
Computer-controlled sterilisation – handled by machines that never get tired (or forget a step).
Super-clean process – washed, soaked for 24 hours (spa day for grains), and sterilised for 180 mins at 121°C & 15 psi.
Alcohol swab included – we’ve got your hygiene covered.
Free from contamination at delivery – because nobody wants surprise guests.
Made with love, care, and maybe a little too much attention to detail.
No-quibble customer service – if something’s wrong, we’ll fix it faster than you can say mycelium.
💬 Important: Please double-check your eBay address — mushrooms can’t walk themselves to the right door.
Sterile Grain Spawn with Injection Port
Available in 1.0 Kg, 1.2 Kg, 1.5 Kg, and 1.8 Kg sizes — each bag includes an alcohol swab, because we’re fancy like that.
Each bag is sealed first, then sterilised (not the other way around — we’re not animals). The process ensures the grain stays squeaky clean and ready for your spores. Made with top-notch organic ingredients for fast colonisation and happy mushrooms.
Perfect for edible and novelty mushrooms (no, not that kind — see note below 👀).
Suit up: gloves + mask = pro mode.
Clean your gear with 70% isopropyl alcohol.
Sanitize that injection port like it owes you money (30 seconds).
Use a new sterile needle. Inject 3–5ml of spores.
Cover holes with micropore tape.
Once 50–70% colonised, give it a gentle break-and-shake (like you’re waking it from a nap).
Optional: Make a DIY glove box from a clear storage tub. (Your mushrooms will think you’re a scientist.)
⚠️ Skip steps = higher chance of contamination. Don’t say we didn’t warn you.
For best results, inoculate ASAP after delivery. If you must wait, refrigerate (max 2 weeks). Beyond that, you’re on your own, adventurer.
We do regular quality control checks — random bags are tested in fruiting conditions because we like to live dangerously.
🍄 Happy mushrooming!
