    • Excellent bags, Mushrooms will grow
Size: 2 LB (2-Pack)
Review Image by Jennifer
Excellent geowing bags for mushrooms. This is my second time buying these. I had a very nice yield from the first bags I purchased. I know they are marketed for special mushrooms, but I used them for portobellos and they worked excellent. Portobello tip, turn the bag on its side after the mixing stage and your mushrooms will have more square footage to grow. The grow medium will still be thick enough to support growth. I will post a picture. I will definitely buy these again. 10/10 would recommend ... show more

    • Great product, customer service, generic packaging
Size: 4 LB
Best product in the category I have ordered. I've ordered nearly 5 similar products, this is not just the most professional company, but was appears as best in class product. Packaging for genetics is fantastic. I'm happy with the products :)! And I got a fair amount of stuff to compare it to!

    • Where's the colonization? Is it in the room with us?
Size: 6 LB
So far I had better results using a bag of uncle Ben's rice and getting my spores to colonize; however, I bought two 6lb bags, and the first took on a terrible odor. The second is sitting in a dark spot under 77 degrees Fahrenheit for three weeks. I did a check after week two by using my phone and looking on the side so as not to disturb the bag. No growth yet, but I'm worried it will be a sud just like the first bag. No growth of any kind, no colonization of any kind. EDIT: All right so I can say this was most likely a complete failure. I did the first and second bag differently thinking maybe I would get different results. First bag- exactly like in the video. Back never inflated due to the CO2. Something I noted with my Uncle Ben's rice bags. It wasn't until I cut a hole in the side and put on a filter that my Uncle Ben's rice bag started colonizing. They genuinely needed oxygen! Second bag- I pulled the bag so that the filter wasn't pressed up against the plastic inside. It was an attempt to make it easy for air to pass in and out of the bag through the filter; However, upon closer inspection of the bag, I noticed that the spore/liquid looks exactly as it did 30 seconds after I had injected it. There's literally no change, no mycelium. The bag has been given a stable temperature, a dark place, one wrapped, and one fluffed out so that oxygen can pass in a lot easier. It's actually quite surprising to me that this yielded literally no results whatsoever, and my first attempt at doing a much more difficult method (uncle Ben's rice, purchasing Coco coir, vermiculite, and pasteurizing it in a pot for 8 hours as a top soil) actually provided me with mushrooms. I was actually more doubtful that that would fail and that this was my backup, but this literally didn't do anything at all! I made sure to sterilize the entire exterior of the bag with isopropyl alcohol as well as the self-healing filter patch on the front, it was only one injection which I made sure to shake before injecting, but to see nothing at all just doesn't make any sense I'm not even seeing any bacterial growth or mold it's literally just a bag that looks the same as it did the day I bought it plus the liquid I injected. I don't think I will be purchasing another bag after both attempts failing and being handled differently in an attempt to get results. What a miserably sad waste of two syringes and my money. ... show more

    • They work!
Size: 2 LB (2-Pack)
Have used this before. First grow was successful, second was not, but that time I was using a very difficult variation and I’m not faulting SS. So it worked. As far as this order it came a day early, so that was good. Looking forward to starting.

    • Might get a dud or damaged bag
Size: 2 LB
Followed instructions but item never germinated while my other bags with the same spores did. The bag lost pressure over time and the grain grew soft. I only used 3ccs which was odd given that’s what the recommendation was.

    • Small business that deserves recognition
Size: 6 LB
Arrived on time and in perfect condition. The compound spores sprouted without any contamination or problems. It arrived with a double protective vacuum sealed bag. Couldn't ask for better customer service when I need help. This is a small family owned business and one of them personally helped me when I wanted to make sure that I was doing everything correctly. 10/10 would recommend ... show more
