The Complete XL ALL-IN-ONE Wood Lover’s Mushroom Grow Bag Kit (6LB) is our largest and most advanced all-in-one grow bag designed specifically for gourmet and functional wood-loving mushrooms. This pre-sterilized, professionally sealed system combines grain spawn, hardwood-based substrate, and a liquid culture syringe into one simple, high-performance grow solution.
With a layered grain-to-substrate design and a massive 6-pound fill weight, this kit delivers faster colonization, stronger flushes, and up to 20% higher yields compared to standard 5LB grow bags — all without the need for a flow hood or sterile lab setup.

Basic grow instructions
How It Works
Inoculate – Inject the liquid culture into the grain layer through the self-healing injection port.
Colonize – Allow the grain to fully colonize (typically 10–14 days).
Mix – Break and shake the bag to combine grain and substrate.
Re-Colonize – Let the mixed substrate colonize for 1–2 weeks.
Fruit – Follow strain-specific fruiting instructions and harvest fresh mushrooms at home.
You can fruit directly from the bag or transfer to a monotub or humidity tent depending on your setup and strain preference.

“Bountiful First Flush!”
“Picked up two spray-and-grow oyster kits directly at the Fourth Plain showroom. The staff gave great humidity advice, and within 9 days I harvested over 2 lbs of fresh clusters! Exceptional local resource.”

“Dr. Myc Additives Are Game-Changers”
