Sterilized Grain Bag with Injection Port (3 lbs)

I ordered the sterile grain bags. So far they work awesome. Only took a couple weeks for myselium to start. Hoping the rest of therebproducys work just as good!

Ive ordered several times and they work perfect, just make sure you let the box sit a few weeks to settle after shipping. Definitely a great buy and youll be greatly rewarded

The whole buying experience was better than expected. Fast shipping. Quality grains and grain bags. I've purchased twice now and look forward to trying additional products in the future.

Stwrile and achieves full colonization every time without fail, I wont order spawn or substrate from anywhere else! No matter the strain they all seem to love this spawn!

North Spore has amazing products with such a slick design and super user friendly approach. Their educational materials and professionalism in this space is unparalleled. I may be biased since I grew up in Maine and love supporting Maine businesses, but even comparing to say fungi perfecti products which I also love, I think these are the best. Sterilized grain port bags work like a charm for colonization, I just built my monotub and am almost ready to mix with my Boomr bag and grow some mycelial fruits.
