Professional Mushroom Cultivation Bags with 0.2-Micron Filter

Designed for mushroom cultivation, these Type 3T gusseted grow bags are made from durable 2.2 mil polypropylene and can withstand the high temperatures required for sterilizing mushroom substrates.

The built-in 0.2-micron filter patch allows gas exchange during colonization while providing fine filtration to help protect sterilized substrate from airborne contaminants.

Their gusseted design expands as the bag is filled, making them ideal for preparing grain spawn, supplemented sawdust blocks, and other sterilized mushroom substrates.

🍄 Great For

  • Grain spawn
  • Sterilized supplemented sawdust
  • Mushroom fruiting blocks
  • Hardwood-based substrates
  • Indoor mushroom cultivation
  • Home and commercial mushroom farms

🔬 0.2-Micron Filter Patch

Each bag includes a 1.5" × 1.5" Type T filter patch rated at 0.2 microns.

The fine filter allows the growing mycelium to breathe while the bag remains closed during colonization.

♨️ Autoclavable

These polypropylene bags are designed for sterilization, making them suitable for use in an autoclave or pressure sterilizer when preparing mushroom substrates.

After sterilization, allow the substrate to cool completely before inoculating.

🌱 Biodegradable Design

These bags provide the durability needed during mushroom cultivation while offering a biodegradable alternative to conventional mushroom grow bags.

📦 What's Included

20 Type 3T Gusseted Bags

Bag Specifications:

  • Size: 8" × 5" × 19"
  • Material: 2.2 mil polypropylene
  • Filter size: 1.5" × 1.5"
  • Filter type: T
  • Filter rating: 0.2 micron
  • Hole: L
  • Quantity: 20 bags

⚠️ Sterile Technique Required

After sterilization, bags should be handled and inoculated using appropriate clean or sterile technique. The filter helps protect the substrate during colonization, but it does not eliminate the need for proper laboratory practices.

How many bags are included?
Each package contains 20 Type 3T gusseted mushroom cultivation bags.
What size are the bags?
Each bag measures approximately 8&quot' × 5&quot' × 19&quot'.
What are these bags made from?
They are made from 2.2 mil polypropylene (PP).
Are these bags autoclavable?
Yes. These bags are designed to withstand the sterilization temperatures used when preparing mushroom substrates.
Do the bags have filter patches?
Yes. Each bag has a 1.5&quot' × 1.5&quot' Type T filter patch rated at 0.2 microns.
What does the 0.2-micron filter do?
It allows gas exchange during colonization while providing fine filtration to help protect sterilized substrate from airborne contaminants.
What can I grow in these bags?
They can be used for grain spawn, supplemented sawdust, hardwood substrates, and mushroom fruiting blocks.
Can I sterilize substrate directly inside the bag?
Yes. These bags are designed to hold mushroom substrate during sterilization.
What does gusseted mean?
Gussets allow the bag to expand when filled, providing more room for substrate and making it easier to form cultivation blocks.
Are these bags biodegradable?
Yes. These cultivation bags are designed as a biodegradable alternative to conventional mushroom grow bags.
Do I still need sterile technique when using filtered bags?
Yes. Proper sterile technique is still important when inoculating sterilized substrate.
What is the difference between the Type 3T and Type 3B bags?
Both bags are the same size and use 2.2 mil polypropylene, but they have different filter ratings. The Type 3T has a 0.2-micron filter, while the Type 3B has a 5-micron filter.
Are these suitable for commercial mushroom cultivation?
Yes. They can be used by both home cultivators and commercial mushroom growers.
