3T Unicorn Bag for Mushroom Spawn (up to 3kg)

If the 10T isn’t quite big enough, the Unicorn 3T steps in with even more room, holding up to 3 kg of prepared grain without breaking a sweat. Same trusted build, same reliable filter, just a bigger bag for people who prefer fewer, chunkier grain runs.

• Size: 8″ × 5″ × 19″ (approx. 20 × 13 × 48 cm)
• Material: Autoclavable polypropylene
• Thickness: Approx. 2.2 mil
• Filter patch: Type-T, 0.2-micron
• Ideal use: Large batch grain spawn production
• Capacity: Up to 3 kg of grain
• Strong bottom seal, so you can shake it like it owes you money

Tough enough for pressure cookers and autoclaves, the 3T keeps its shape under heat and delivers reliable airflow through a 0.2-micron filter patch, giving your mycelium space to do its thing without inviting any unwanted guests.

The Unicorn 3T is for growers who think bigger bags mean less faff. And they’re right. More capacity, fewer bags, easier workflow.

If 1 kg is your magic number, check out the 4T. If around 1.8 kg hits the spot, the 10T is your bag. But if you want to go large, the 3T is waiting.
