Inject & Grow All-In-One Mushroom Grow Kit

Our Inject & Grow All-In-One Mushroom Grow bags are one of the simplest and most reliable ways to grow mushrooms at home. Designed to remove the usual setup headaches, they combine grain and substrate into a single, fully sterilised but expertly packed with nutrients grow bag, ready to inoculate on arrival.

Whether you’re growing mushrooms for the first time or you’ve been cultivating for years, these bags offer a clean, controlled environment that supports super fast colonisation and strong yields, without complex equipment or specialist knowledge.

How it works

1. Inoculate through the self-healing injection port using spores or liquid culture (not included)

2. Allow colonisation to begin, then mix once growth is well established

3. Fruit directly from the bag or in a suitable fruiting environment

No complicated setups, no confusing instructions, and no need to piece together advice from outdated forums.

What’s inside the bag

Each Inject & Grow bag contains a carefully prepared all-in-one substrate blend made from natural ingredients, including grain, coco coir, vermiculite and gypsum. The substrate is hydrated to optimal levels and sterilised under controlled laboratory conditions to support healthy mycelium growth and minimise contamination.

The balanced grain-to-substrate ratio provides the nutrients mushrooms need for rapid colonisation and consistent flushes.

Storage information

For best results, we recommend using your Inject & Grow bag soon after delivery. If you need to store it, keep it refrigerated. When stored correctly, the bag will remain viable for several months.
