## Description

desertcart.com : Booming Acres Booming Grains | 3lb Sterile Custom Grain Blend Including Injection Port| Sterile Hydrated Grains for Growing Mushrooms : Patio, Lawn & Garden

Review: I'm glad I gave it a try. - 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.
Review: Molded and did not grow - Spores were injected as instructed, placed in dark closet and just turned to mold and didn't grow as expected.
