Great product and very well packaged

I’ve used Olympus Micos grain and spawn bags in the past with great success, I highly recommend them.

I ordered an all in one for the first time and I’m very impressed with what I received. Others I’ve tried have arrived with the grow bag just sitting in the box, this arrived in a box with the grow bag itself vacuum sealed in a very thick plastic bag. It took me a minute and a few emails to figure out that the super thick vacuum sealed bag is part of the packaging and not part of the grow bag! If you’ve used grow bags you will know what I mean… they don’t come vacuum sealed like this was.

I just inoculated the bag so I can’t judge the results yet, but this product top notch out of the box. I have to say the Olympus Mico customer service team is amazing! They were so helpful and even sent me a picture to help me figure out what I was doing.

I’ve been growing my own mushrooms since November of 2023, I’ve tried all the major brands with varying degrees of success, but I’d say save your time and money and order from these guys.
