Description

XL All-in-One Mushroom Grow Bag – 6 lbs (Manure-Loving Varieties)

Looking for the biggest yields in the simplest way possible? Our XL All-in-One Mushroom Grow Bag is one of the largest on the market—packed with 6 full pounds of sterilized grain and substrate, ready to produce massive harvests. Just add spores or liquid culture and watch your mushrooms thrive. Perfect for growers short on space but hungry for serious results, this extra-large bag delivers the convenience of a compact setup with the output of a much larger system.

Each bag comes layered with over 2 lbs of our proven 5-grain blend and 4 lbs of nutrient-rich Select Bulk Substrate—pressure sterilized for 3.5 hours and shipped fresh daily. This premium mix has been tested to ensure vigorous colonization and heavy flushes, giving you a head start toward abundant harvests.

Why Choose Our XL Grow Bag?

  • Bigger Than Standard Bags: At 6 lbs, it’s nearly twice the size of most grow bags, designed for maximum yields.
  • Massive Harvest Potential: Produce flush after flush—perfect for anyone serious about volume.
  • Simple Setup: Just inject spores or liquid culture into the self-healing port and let nature do the rest.
  • Premium Quality Mix: Sterilized blend of grain and substrate selected for fast, healthy growth.
  • All-in-One Convenience: No monotubs, no extra equipment—everything happens inside the bag.
  • Durable Self-Supporting Bag: Built-in 0.22 micron filter patch ensures airflow and easy misting access.

How It Works:

  1. In a sterile environment, inject 5–7cc of spores or 10cc of liquid culture into the black injection port.
  2. Incubate at 72–76°F until the grain is 75% colonized.
  3. Break and shake to spread mycelium evenly, then allow 10–14 days for full recolonization.
  4. Place in indirect light (12+ hours/day).
  5. Cut the top open, mist the inside daily, and watch mushrooms fruit in abundance!

What’s Included:

  • 1 XL 6 lb sterilized grow bag (2 lbs of 5-grain + 4 lbs Select Bulk Substrate).
  • 0.22 Micron filter patch & injection port (self-supporting).
  • Step-by-step full color instruction guide with photos.
  • Online video access for extra guidance.

Whether you’re a beginner or an experienced cultivator, this is the ultimate one-bag solution for growing dung and grain-loving mushrooms. If you want one of the biggest producers available, this is it. Just add your culture—and get growing.

Got mine today!

Just inoculated and everything looks good! This thing is way bigger than the 4lbs I’ve used. I’m sure it will work the same! Peace
