North Spore Sterilized Grain Bag with Injection Port (3lbs) | Home-Made Mushroom Spawn of Any Species | All You Need is a Spore Syringe (not Included) | Better Substrate Than Rye Berries (1)

Gonna give it 5 for now. Seemed like the top 3/4 was realy dry and the bottom 1/4 mushy but I’m gonna just wait and see. I used to prepare bulk WBS so I have a good idea what it should look like. Seller shipped fast and was professional. Also no contams so far and that’s always a plus. Also it really irritates me when I see people give negative reviews when 1. people don’t know what they’re talking about and 2. If there’s a problem, wait and see if the seller is willing to make things right if they are indeed at fault. Reviews are important to sellers and people leaving negative reviews about topics they aren’t qualified to review is a huge flaw in the system.

100% disgusting are usually order from them and receive great product but this time was just absolutely disgusting I opened up the package and got a huge width of this black moldy powdery substance that had me sneezing like crazy and I’m hoping I don’t get sick from this 100% disgusting are usually order from them and receive great product but this time was just absolutely disgusting I opened up the package and got a huge wif of this black moldy powdery substance that had me sneezing like crazy and I’m hoping I don’t get sick from this& onTop of this I have to put my little project on hold.

3rd time buying these seed bags for my spores, 3rd time theyve molded over with black mold. Bought $30 bag from a mushroom supply company that actually PROPERLY prepares theirs so they arent contaminated and overly wet, and I got a great harvest.DO NOT BUY THESE SEED BAGS IF YOU ARE GROWING MUSHROOMS. Total waste of valuable and and hard to come by spores, which is what sucks, the fee dollars I paid for them isnt a big deal.

I used this to grow legal mushrooms Upon sterilizing my syringe, and ensuring that the room and space was sterilized, I inoculated the grain bag (I also ensured to used rubbing alcohol on the injection port). After a couple days I did notice some growth, so I promptly shook the bag. 2 days later the unmistakable marks of blue and green mold started showing on the sides. After ruling out everything else that could of gone wrong, I have come to the conclusion that the grains in the bag themselves may not have been properly sterilized.

10/10 would recommend this product, it was exactly what I needed for my mushroom cultivation. So excited to have found a reliable & sterile grain bag. I did not have contamination issues and the self-healing port is dummy proof. I have ordered from Northspore's website before and I'm excited to see them on prime now.So excited to grow at home! I did not have contamination issues and the self-healing port is dummy proof.I have orded from the Northspore website beofre and im excited to see them on prime now.

I’ve received my bag today and when I opened it there was a rip in the side, looked like it maybe happened during delivery. Hopefully it still works will leave an update

The product was exactly as discribed, the only issue is that amazon had damaged it before shipping (the box was pristine while the actually packaging was damaged significantly)

My first bag gave me some trouble, but I'm new to this and besides having no contam, this company or myself had no way of knowing why it didn't work. But after contacting them to try and get help I was automatically offered a replacement. Top notch company from my home state that also does the right thing! 100% reccomend and will buy again.
