Take your mushroom-growing projects to the next level with our Sterilized Rye Berry Grain Spawn Jars. This 4-pack of quart-sized jars is pre-filled with fully hydrated and sterilized rye berries, a nutrient-rich grain perfect for cultivating robust mycelium. Designed for convenience and precision, each jar includes a self-healing injection port for easy inoculation and a 0.22-micron gas exchange filter to maintain optimal airflow while preventing contamination. Whether you’re a hobbyist or an experienced grower, these jars are ready to use right out of the box.

Great product and super fast shipping
I've ordered from out-grow 3 times now. They're 100% committed to their customers, providing quality product (they don't skimp out on materials) and service. Every time, they sent the order same day. I get my ordered delivered within 2/3 days. Substrate is always freshly prepared. They know what they're doing.
