Bag It & Tag It: The Hipster's Guide to Growing Mushrooms with Grow Bags

Hello, mushroom enthusiasts! Whether you're deeply involved in mushroom cultivation or just starting to explore this fascinating hobby, you'll find that mushroom grow bags are incredibly valuable tools. Let’s dive deep into what these bags are, how they work, and how they can transform your cultivation practices into a more productive endeavor.

What Is a Mushroom Grow Bag?

Mushroom grow bags are specialized containers used by mycologists and mushroom hobbyists to cultivate mushrooms efficiently and cleanly. Typically made from a polypropylene material, these bags can withstand high temperatures during sterilization processes. Here's a closer look at the components:

⦁ Gusseted Design: The bags feature a gusseted design, which means they have folds that allow them to expand to accommodate more substrate — such as grain or sawdust. This design is also beneficial during the sterilization process as it provides space to insert a filter.

⦁ Autoclavable: They can endure the high temperatures of autoclaves (up to 250 degrees Fahrenheit), making them reusable and reliable for sterilizing substrates without the risk of melting.

⦁ Polypropylene Material: This type of plastic is known for its durability and resistance to melting under high temperatures, which is crucial during the sterilization process.

⦁ Filter Patch: Perhaps the most critical feature, the filter patch allows for air exchange — letting air in but keeping contaminants like mold spores and bacteria out. This is essential for the healthy growth of mushroom cultures.

Uses of Mushroom Grow Bags

Grow bags are versatile tools in mushroom cultivation, commonly used for:

Spawn Bags

• Large-scale production: Ideal for producing large volumes of grain spawn, these bags simplify the process of breaking up and mixing the spawn, which accelerates the colonization of the substrate.
• Ease of use: Unlike jars, which can make retrieving colonized spawn difficult and messy, bags allow for easier manipulation and less risk of contamination.

Fruiting Blocks

• Efficient cultivation: After mixing spawn with substrate in the bag and allowing for colonization, cultivators can initiate the fruiting process directly in the bag by introducing fresh air and proper humidity.

Mini Fruiting Chambers

• Alternative use: Bags can also act as mini fruiting chambers for smaller scale or experimental batches, where maintaining micro-environments is crucial.

Tips and Tricks for Using Mushroom Grow Bags

• Reuse of bags: If not opened for fruiting, bags can be reused for other purposes like pasteurizing small batches of casing layers or creating mini straw logs.
• Selecting filter size: The micron rating of the filter is crucial — lower ratings (0.5 micron or less) are best for protecting against contaminants.
• Choosing the right size and thickness: Bag size should match your substrate volume needs, and thicker bags, while more expensive, are less prone to tearing during handling.

Sealing Techniques

Properly sealing grow bags after inoculation is vital to prevent contamination:

• Wire twists or zip ties: Simple and effective for small-scale operations.
• Impulse sealer: Recommended for larger operations to save time and ensure airtight seals.

Environmental Impact and Sustainable Options

Given the concerns over plastic waste, some cultivators are exploring biodegradable grow bags, although finding a product that matches the durability and utility of polypropylene bags remains a challenge.
