North Spore Organic Sterilized Hydrated Grain Bag w/Self-Healing Injection Port | Sterile Mushroom Spawn Bags w/ 0.2 Micron Filter Patch | USDA Certified Organic (1 Pack)USDA Organic

Thymine have worked wonderfully, Zero issues so far, and their incredibly easy to use!

This sterilized, hydrated grain spawn bag worked perfectly for my lion’s mane mushroom grow! It arrived well-sealed, clean, and fully hydrated—ready to inoculate right out of the box. Colonization was fast and even, and I got a great yield. Super convenient and reliable for home cultivation. Highly recommend for any mushroom grower!

Myc started growing like 5 days in what a great bag

The only grain I will buy. Nice and tightly packed with fresh hydrated and sterile millet. I inoculated it with a spore syringe from a reputable supplier. Set the temp to 77, and let it sit in the dark cozy closet. I was careful to minimize possibility of contam. Sprayed the bag all over w alcohol first thing. Applied fire to the syringe. Sprayed the grow room w isopropyl alcohol too. You cant do too much sterilizing. Use sterile gloves if you have them. Mycelium noticeable in a week. Spreads rapidly. After the second week, I had about 2 pounds of pure, fresh fluffy mycelium. Went on to grow the biggest flush ever in a monotub. Happy growing!

The top of this was wide open. Not sealed at all. I could reach my hand in and touch the grain. Complete waste of money. Also wasted my spores. I think they forgot to seal it at the factory.

Always great stuff from this company. I have always been 100% satisfied with all north spore products.Could cost less tho

This takes a lot longer to fully colonize compared to other brands I have tried. It's been over a month and less than half is colonized.

This was my first attempt at growing mushrooms. I have still not learned my lesson - always read the directions! So I set the bag on a 80 degree F mat for 2 weeks before inoculating it. Then I injected 10 cc of spores (too much) and accidentally turned the heat mat up to 100 degrees overnite. Then I turned it down to 80 again and waited 2 weeks. Only a tiny bit of mycelium growing. I got impatient & kneaded the bag completely, found there were a few golfball sized clumps of mycelium. I waited another 2 weeks, there seemed to be about 1/3 diffuse mycelium so I broke it all up again & turned the mat down to 75 degrees. After 2 weeks I turned it down to 70 and now 10 days later it looks like most of the grain has mycelum but it isn't all interconnected like people show on their YouTube grow channels. I wonder if I have inadvertently frightened the mycelium into a state of severe cautiousness, not knowing what will happen next. I hope that if I just stop messing with the bag, let it sit in cool dim space the mycelium will eventually realize it's ok to grow again. There doesn't seem to be any contamination, there is still moisture in the bag, I can smell that earthy mushroomy smell from the filter area. I got a grain bag from another company, inoculated & handled the same exact way and it is now fully myceliated & ready for the next step. I will try making my own grain growing material in the future to try & save a few bucks. - I Should Have Read The Directions First!
