Drippy Corn Mushroom Spawn Bag

We think we’ve made the fastest spawn bag on the planet 😎. Our 3 lb drippy corn spawn bag is made with US-grown, non-GMO corn and certified organic erythritol for faster, more aggressive mycelium growth than traditional drippy corn or other grain spawn like rye, milo, millet, or wheat. Drippy corn has large kernels that are easy to break up and an added clean fuel source for your mycelium. Mycelium responds best to simple, stable carbon sources. Using organic erythritol instead of corn syrup (like most drippy corn on the market) avoids caramelization, reduces grain stickiness, and maintains clean separation, creating extremely fast, high-performing and consistent spawn. Sterilized in our industrial-grade autoclaves and sealed in a Unicorn® brand bag. Pair with our bulk substrate for a monster grow.

50 YEARS OF EXPERIENCE

We are a team of mycologists with over 50 years of combined experience growing mushrooms. Our goal in creating Magic Bag was to make the mushroom growing process easy, fun, and accessible while providing the highest yields possible.

WHY WE GIVE AWAY OUR PROFIT

When we started Magic Bag, we decided that making a beneficial impact was more important than profits and that the mushroom world was the wrong place for a profit-first mentality. We donate 100% of our profits to 501(c)(3) organizations doing groundbreaking research on the beneficial effects of certain mushroom species. Visit our Donation section to learn more and view our donation records.

NON-GMO & GROWN IN USA

Magic Bag Drippy Corn Spawn Bags use only non-GMO popcorn grown in the USA.

NO CONTAMINATION

Contamination is the nemesis of mushroom cultivators. Our industry-leading medical grade sterilization process is key in reducing the chances of contamination in our spawn bags. We use top-of-the-line, commercial steam sterilizing electric autoclaves set at 250 °F and 15 psi over a 2.5 hour sterilization period to ensure our bags are sterile and resilient to contamination.
