Booming Grains | 3lb Sterile Custom Grain Blend Including Injection Port| Sterile Hydrated Grains for Growing Mushrooms

Excellent substrate for your fungus cultivation.I wasn't seeing results in colonization and thought the grain may have been the culprit. Perhaps too dry. But following an educating discussion with the seller it turned out to be bogus spores. The seller sent a replacement immediately and included a source for real spore syringes. The grain is now almost fully colonized about ready to fruit.Good product, great advice a top tier customer support. You can count in this seller to get the results youre looking for.

I've grown gourmet and medicinal mushrooms for personal use for a few years, but I've always sterilized my own grain mixes (with wildly varied results, I must add). This was my first try with a pre-sterilized spawn bag and I was initially skeptical from reading the reviews, but new issues with finding bulk grain in my area pushed me to have a go.I bought one bag and inoculated it the same day. A week passed with no visible signs of contamination or mycelium, so I tried another few CC's of spore fluid. Another week passed, nothing. I was ready to contact the supplier until I checked the bag a third time and lo and behold I have mycelium! And even better, still no signs of wet rot or contamination, so I know the grain as well as my spores were good quality. I intend on purchasing from this vendor again soon and trying their other products.One thing I feel I must mention for anyone else reading these reviews and thinking about buying some of these bags; the tape over the selff-healing onjection port is supposed to be on there. Somebody complained their bag tore when they tried to remove it, and I almost tried the same thing... The bags are fine as they arrive, save yourself the hassle and just inoculate and set it somewhere dark and warm. I expect my future purchases will be equally satisfactory.

I ordered 3 of these bags and it got to me fairly quick so I let it sit for 3 4 days on my fridge to see if any bacteria was growing it wasn’t so I bought a syringe to inoculate them I used the same syringe flame and alcohol sterilized did all 3, and 1 out of 3 were successful the other 2 smelt like the juice at the bottom of a trash can don’t get this brand of grain

Excellent product.

Good quality, decent amount, my fault for contamination. All went smooth until I combined with substrate and then when in fruiting conditions, it got mold.

Every mushroom spore that I have injected into this company's grow bag have fully successfully grown in large amounts definitely worth the price the size of the bag is perfect quality and I love the functionality because I don't have to sterilize my own grain

Bag contaminated on arrival. Would not recommend. Only reason I gave 1 star is because I couldn't give 0

Grain arrived with contamination. Fortunately I noticed before wasting spores on this
