Out Grow's Mega Mix Sterilized Grain Jar brings a revolutionary blend of yellow popcorn, red milo, and rye berries. This unique combination ensures a wide range of nutrients and minerals that are essential for robust mycelium growth. Hydrated in natural spring water and sterilized for three hours at 15 psi, these quart jars offer unmatched purity and efficiency.

The jars come equipped with a 5-micron filter patch, allowing for optimal gas exchange—an essential factor in accelerating colonization. Each jar weighs approximately one pound and has a volume of one quart. To use, simply inoculate your jar with 5 cc of your chosen inoculate and mix gently. The jar is designed to thrive in room temperatures between 65 and 75 F. Typically, you can expect mycelium growth to begin within 1-2 weeks and full colonization to occur around 4-6 weeks.

Notably, one quart jar can inoculate up to five pounds of bulk substrate. This makes it incredibly cost-effective and ideal for both hobbyists and commercial mushroom cultivators. Although best when used fresh, the jar's robust design allows for storage in its original packaging in a cool, dry location for up to three months.
