4T Unicorn Mushroom Bag Type for Mushroom Spawn Production (400g > 1kg)

The ever-popular Unicorn Bag, from Unicorn Bags. They really committed with the name, but sadly have failed to follow through on making a bag that either could or does hold a Unicorn. I’ve checked every shipment and as obviously Unicorns aren’t real (sorry kids) there hasn’t been a single one present, there’s just a load of nothing in the bags. Full of all our thoughts and prayers. Bastards. 

I numb this crushing disappointment by making the team fill the bags up with all this grain we’ve got lying around, and coincidentally the bags are really good at holding it. You can get them as hot as you like and they don’t get damaged, so they’re perfect for the autoclave, and they’re sturdy as fuck so the weight of the grain doesn’t cause splits. 

Unicorn Bags have been making these bags specifically for mushroom cultivation since 1990, and they’ve made quite a few in that time. Whatever the technical term for “Master Bag Craftsmen” is, they’re that, so why buy anything else?

You can only buy these from them in massive amounts, which for the home mushroom cultivator is definitely overkill - we’ve got loads of room here at MycoPunks HQ so we can buy shitloads at a time and sell them to you in as small a quantity as ten, if you like (although feel free to buy as many as you like, we’ll just get more).

Technical specs? Yeah go on then:

This side-gusseted breathable bag gives a sturdy stand-up bag after filling and a strong bottom seal. They manufacture it with equipment they designed and with proprietary additives, Unicorn Bags are pliable at any temperature as well as after sterilization. The bag opening is designed for easy sealing and the bag’s bottom seal can withstand agitation.
