Simple process

From bag to harvest in 3 steps.

01

Inoculate

Inject your liquid culture, spores, or agar plug directly through the self-healing injection port. No flow hood or open transfers needed.

Day 1
02

Colonize and Shake

Keep the bag at 20 to 25°C in a dark spot. When 50% colonized, shake to break up and redistribute the mycelium for faster, even coverage.

Days 7 to 21
03

Harvest and Enjoy

Once fully colonized, introduce fresh air and humidity. Pins appear within days. Harvest just before the caps fully open for the best flavour and yield.

Days 21 to 35
Ingredients

0.2 Micron Filter Patch
Medical-grade gas exchange. CO2 out, fresh air in - blocks all contaminants, no sterile enclosure required.

Common questions

Everything you need to know.

Yes. Our All-in-One bags are designed specifically for beginners. Everything is pre-sterilized and ready - you only need to inject your liquid culture or spores through the built-in injection port. No pressure cooker, no lab, no mixing required.
A liquid culture syringe, spore syringe, or agar plug to inoculate with. That is it. The bag contains everything else - sterilized grain, substrate, filter, and injection port.
Colonization typically takes 10 to 21 days depending on species and temperature. After full colonization, pins usually appear within 5 to 10 days. Total time from inoculation to first harvest is usually 3 to 5 weeks.
Most growers get 2 to 4 flushes from a single bag. After harvesting, soak the block in cold water for 12 hours to rehydrate, then return it to fruiting conditions.
Store in a cool, dark place away from direct sunlight. Use within 90 days of the production date. Do not freeze.
We replace it completely or refund you - your choice. No forms, no questions, no waiting. Just contact us.
