This kit is super convenient and worked even better than expected. The 30 ml liquid culture included is incredibly useful — I inoculated it first, and the mycelium took off fast and clean. Having it prepped ahead of time made the whole process easier and helped the bag colonize quickly. I fruited the bag inside a small monotub, and it performed perfectly. The substrate stayed evenly hydrated, the airflow was just right, and the mushrooms came out thick and healthy. The setup didn’t take up much space, and I still got a really nice harvest on the first flush. Overall, this is a well-thought-out kit that makes growing in small spaces simple and reliable. The culture jar and grow bag combo are a perfect match — definitely worth it if you want great results without a complicated setup!

This I believe is my second review on the myco Labs and I got to tell you despite having an issue with my first delivery. Michael ladds was extremely quick to fix that. Not to mention when they gave me a replacement product, it fit to the expectations. I must say I wasn't disappointed the first time as inconvenient as it was. There was no issue because their products are backed and I got to say all of Michael Labs products have been of great quality. I even own the dehydrator and I must say works great for all vegetables

The Myco Labs all-in-one mushroom grow bag with spore germination jar has never once failed me. Four pounds of ready grain and substrate arrive clean, sealed, and eager to serve, and not a hint of contamination has dared appear. So easy even I can do it without the helps help. I am aware that others have not shared this fortune and some report unwelcome intrusions, so I may very well be an edge case. Yet I confess I go overboard at every stage, practicing cleanliness and decontamination as if preparing for surgery in the estate drawing room. On occasion I will even break the bag apart and blend it into a personal substrate mix of my own design, allow it to further colonize, and then usher it into fruiting. For gourmet strains these bags are flawless, and one might say even the high priests of the craft would grant their blessing. Dependable, consistent, and worthy of trust.

This one worked perfectly for inoculation and incubation- the moisture and grain to substrate ratio were spot on for my needs. Due to my own preference, I ended up moving the fully colonized cake to a fruiting chamber and it's coming along nicely.

Excellent company. I have been doing business with them for years. Great quality and amazing customer support. I have only ever had 1 bag that was bad (bacteria) I let them know and they replaced it free of charge no questions asked. Excellent multi grain multi fruiting option for home growers. And now … with Myco starter kit it’s a no brainer.
