Self healing injection port is working solid, no contams 3 weeks post injection- which also points to the fact that they autoclaved this thing well. It's been well over a month since I got it and that means it's probably been a month and a week since it was packed. The price is a steal for the work I avoided, and considering how little output I do it's just easier. North Spore is solid and they've been in the game for years, I wouldn't shave off a couple dollars to get a version that I would even have to worry about mold with. It was good to go out of the box, just unfold it gently and don't get your filter wet. I don't know if it's waterproof, I always assume no. Oh, no big moisture spots or visible dryness either if you're worried about that.

Have ordered plenty of the sterile grain bags from North Spore, the bags are always sterile, the bag itself is really a high quality bag, and personally my special spores (IYKYK) have continued to take very well to these. Also the coupon to ITW was super helpful, if you’re looking for good spores ITW and North Spore is an absolutely UNBEATABLE cost-benefit! The fungi loves it, and that is a TRIP…

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!

Haven't had a problem with a bag yet! I've been able to colonize and spawn to bulk with every single one. I will say this, North Spore is a brand i trust. There's plenty of other bigger and cheaper grain bags on here..but I know this works, it's clean, and if there is ever a problem, North Spore will take care of it. Not if you inoculated and nothing grew...im talking about if the grains don't look right, the bag isnt vacuum sealed, or it smells bad. Quality is 10/10. It does its magic thing every single time :)

Junk! These bags have holes in them that cause massive contamination. Really disappointing. And, yes, I was careful. The holes in the bag were not apparent until weeks later. This is a defect not user error. Do not buy!
