MaxGro Sterilized Grain Bag

The MaxGro Sterilized Grain Bag is built for cultivators who want rapid colonization and expansive growth from day one.  Packed with a balanced corn and rye berry mix, this 3.5lb bag combines the glucose-rich kickstart of corn with the nutrient-dense, structural backbone of rye.  The result?  Fast, vigorous mycelial growth and a stronger foundation for bulk expansion.

Each bag is sterilized in a commercial-grade autoclave and fitted with a self-healing injection port, ensuring a clean and simple inoculation process. With carefully dialed-in moisture content, the MaxGro bag promotes even colonization while preventing clumping and stalling.

Whether you’re inoculating with liquid culture, spores, or transfers from agar, MaxGro delivers consistency, speed, and scalability giving you the performance edge you need.

Why MaxGro?

• Rapid colonization thanks to corn’s simple sugars (glucose)

• Resilient growth supported by rye’s complex nutrients and structure

• More volume (3.5lb) than standard 3lb bags for greater expansion potential

• Sterile, sealed, and reliable with a self-healing injection port
