White Milo Mushroom Jar – Sterilized 1 Quart for Mushroom Cultivation

Out-Grow’s White Milo Mushroom Jar – Sterilized 1 Quart offers a fast-colonizing, lab-prepared substrate for mushroom growers seeking clean, consistent results. White milo grain is a popular choice for cultivation due to its small grain size and high inoculation point density, allowing for more even and accelerated mycelial colonization than traditional rye.

Mushroom Cultivation Jar with Injection Port and Filter Patch

Each mushroom jar is filled with fully hydrated, pressure-sterilized white milo and sealed in a reusable quart jar. A self-healing injection port makes inoculation clean and easy, while a 5-micron filter patch supports sterile gas exchange during colonization. This lab-tested combination helps create a contamination-resistant environment that supports strong, healthy mycelium growth.

Designed for Versatile Growing and Bulk Inoculation

The white milo mushroom jar is perfect for grain-to-grain transfers and for inoculating up to 5 pounds of bulk substrate. Its fast colonization timeline and clean handling make it ideal for both small-scale experimentation and scaled-up grows. Whether you’re growing oyster, lion’s mane, or other gourmet strains, this jar is built to support reliable performance and high yields.
