Pack of 100 Unicorn 4-A ideal for standard grow blocks

This bag is identical to bag Type 4-B and bag Type 4-T except that it has a Type A .5 micron filter.
This side-gusseted breathable bag gives a sturdy stand-up bag after filling and a strong bottom seal. We manufacture it with equipment we 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.

Yes, these Unicorn bags are still the original brand made in the USA to the high-quality standards Unicorn bags are known for. All of our Unicorn bags are Polypropylene which means they are autoclavable.

You can even save more time with MushroomMediaOnline’s own Fast Fruiting Mix that is the ideal mix of 50/50 hardwood sawdust substrate supplemented with 50% soy hulls.
