Premium 5-Grain Mushroom Spawn Bags | Sterilized Grain Spawn | Injection Ports | 2 Quarts Each Bag | 2 Bags per Box

I've used these grain bags a few times and never had an issue. So much easier then making them myself and sterilizing them. These produced some large fruits in a monotub. I used their premade CVG substrate as well. I used 2 grain bags and 2 5lbs CVG substrate bags.

I've ordered like 10 of these and had zero contamination with all the oyster mushrooms I've been growing. I use live culture so maybe that's why they've been working so well for me. Either way, thought I'd show some appreciation by leaving a good review. Seems like best price on Amazon currently as well.

Works great, had no issues.

These bags are too dry and cause MAJOR stalling... they havent shown any growth since the initial inoculation. I had growth and then nothing for weeks It's been at this stage for weeks now

1st time attempting anything within the hobby of mycology and enjoyed reasonable success with this product. Both strains of fungi that I innoculated these with, loved this grain combination. Since using this product to fruition, I have used multiple other mediums with very little success, truly highlighting the significance of starting with a STERILE grain product to innoculate with. That being said, the only reason it doesn't get 5 stars( I typically don't give 5 star reviews) is cuz it does seem overpriced. The grain itself is ridiculously cheap, so for this price : ur basically paying for their usage of an autoclave/pressure cooker... making this a product priced for the convenience of not buying/owning/using pressure cooker. If it ever comes down in price , even slightly, I will more than likely be purchasing more. Til then: its brown rice for me!lol. Ps- dont forget to employ ur aseptic technique. Like everybody else says: its paramount to success in this field!

Myco labs have good products

Excellent better than north spore in my opinion

The grain is fine and works for the purpose, however, the packaging is so dumb. They use tape on the grain bags to keep them compact inside the box. This doesn’t make any sense because the tape is really hard to get off. It is clear and it’s obviously very sticky so when you go to open the bag up, it’s really really easy to tear. If you tear it, the bag is then useless because it’s become contaminated and you have to get a new one., is that their marketing tactic? To me this is a product that is clearly not used by the people who designed and or package it. I included photos so you can see what I’m talking about. The tape is difficult to peel off.
