XL All-in-One Mushroom Grow Bag (6 lbs) for Manure Loving Mushrooms

XL All-in-One Mushroom Grow Bag (6 lb)

The XL All-in-One Mushroom Grow Bag (6 lb) is a high-output all-in-one mushroom grow bag built for growers who want bigger flushes with the same simple workflow. This sterile grow bag combines grain spawn and bulk substrate in one ready-to-inoculate system, making it easy to inject, incubate, and fruit without needing a full monotub setup.

Each XL bag includes a larger, pre-sterilized layer of 5-grain spawn paired with our Select Bulk Substrate for strong colonization and higher yield potential. We pressure-sterilize these bags in-house and ship fresh so you can start with clean materials from day one. If you later want to scale up even further, explore our monotub collection or browse our bulk substrate options.

This example of our XL 6 lb bag was fruited in our Ecosphere Grow Tent, and the top half of the bag was removed.

How to Use This 6 lb All-in-One Grow Bag

1. Inoculate through the self-healing port: inject 5–7cc of spores or about 10cc of liquid culture into the grain section.
2. Incubate in a warm area around 72–76°F until the grain is about 75% colonized.
3. Break & Shake to distribute mycelium, then allow the bag to fully colonize, typically in 10–14 days.
4. Introduce fruiting conditions with indirect light, fresh air, and proper humidity.
5. Fruit & harvest: open the top and mist the inside walls as needed to maintain humidity, or transfer into a larger fruiting setup if desired.

Ideal For

• Growers who want bigger runs without switching immediately to a monotub
• Small grow spaces like shelves, closets, and compact rooms
• Testing cultures before scaling up to larger grows
• Anyone who prefers an easy, low-maintenance workflow

Want higher yields per run? Upgrade to a monotub grow setup to scale production and increase output using bulk methods.
