INTERGALACTIC MUSHROOM 3lb Sterilized and Vacuum Sealed Organic Rye Berry Grain Bag with Injection Port- 3lbs (2 Bags Each 1.5lb)

Bags worked great for a beginner. I got these for my niece. They're very easy to use . Recommend for beginners , yes .

Grain is perfectly hydrated and fully sterilized !! Did a break and shake after only 5 day post inoculation and was fully colonized in another 6 days !! Just ordered another 2 bags to get another couple shoeboxes going!! Making my own grain spawn is such a pain in the a## and is more cost effective to just get it from a reputable vendor such as this one !! Mush Luv, Mikey M.

BOTH bags became contaminated with TWO different mold species while my 8 other jars inoculated at the same time are healthy. No refund or exchange available.. aside from that packaging and material were good

I think most people who are leaving negative reviews aren't following the directions EXACTLY. You must follow them to a T and you must try and reduce any potential contamination to your best ability (i.e spraying the bag, scissors, syringe, tape roll, hands, surface down with at least 70% isopropyl AND ensuring to cover the injection port IMMEDIATELY after use. I do not think any of these negative reviews are realistically caused by the seller, but are rather caused by inexperienced mushroom growers, or just those who are bad at following directions.BOTH of the bags purchased for ~$40 had shown mycelium growth very fast (for pink oyster), and somewhat slow for some other totally legal strains i am growing as well.

1 bag was fine the other bag got contaminated not the company fault
