When it comes to production no 5lb bag available outperforms this kit. I would love to see them switch to a wider mouth jar for spawn however I that is this kits only fault.

These mushroom growing bags are hands down the best I’ve used! The fruits these bag yielded are monstrous . The sterility is flawless and the bag is very sturdy. The filtration system provides excellent gas exchange without compromising cleanliness, leading to rapid colonization and impressive yields. If you’re looking for a reliable, contamination-free growing experience with consistently high output, these bags are a must-have! This is officially my only brand now.

This kit is only a little more work than the all-in-one bags you get on Amazon only it produces much better and more fruits. Use with a small amount of the horse booster and you'll get an excellent result. Good for more than one harvest of fruits and the mycelium left behind after the 3rd harvest can be used in a monotub or outdoor bed as long as you're careful about not letting any mold in wash your hands with rubbing alcohol before you open to spray water or harvest fruit and you should have no problem doing this.

*note I am not a professional grower I only grow my mushrooms for legal and health reasons*

I started with this brand 1st, but because I am new to all this, I have ordered the same all in one bags from 3 or 4 other companies! Midwest is byfar is the most professional and got results!!! So I'm coming back to my proven champ!!! On top of that they have a list online for the best spots to get spores. And that is so much better than who I was using!!!

Beautiful spores
