Inject & Grow Mushroom Grow Bag Expansion Bundle

Growing mushrooms at home can feel like a maze at first. Too many steps, too many variables, too many things that can go wrong.

This bundle simplifies the process while giving you the flexibility to expand your grow beyond a single bag.

At the centre of the bundle is our Inject & Grow All-In-One Mushroom Grow Bag, a sterilised bag combining grain and substrate for fast colonisation and simple cultivation.

Alongside it you’ll also receive separate sterilised millet grain spawn and CVG bulk substrate, allowing you to prepare larger bulk grows once your spawn is ready.

Everything is prepared under sterile laboratory conditions using high quality ingredients, so you can focus on growing rather than troubleshooting.

The simple idea

• Inject & Grow bag for simple beginner friendly cultivation
• Additional grain spawn and CVG substrate for expanded grows
• Clean sterilised preparation for reliable results
• A flexible bundle for growers ready to scale beyond a single bag

What you can expect

• Beginner friendly cultivation workflow
• Strong colonisation with balanced grain and substrate ratios
• Flexible growing options depending on your setup
• Less time troubleshooting, more time enjoying the grow

How to use

1. Inject the Inject & Grow bag through the self-healing port using your chosen culture or spores (sold separately).
2. Colonise in a clean warm location until strong mycelium growth develops.
3. Mix the bag once around 30 percent colonisation to spread growth evenly.
4. Expand using the included grain spawn and CVG substrate once fully colonised.

You will also have access to our online step by step guide with practical tips to help you dial in your grow conditions.

Recommended growing conditions

• Temperature Colonisation around 24 to 27°C. Fruiting around 21 to 24°C.
• Humidity Aim for around 90 percent humidity during fruiting.
• Light Colonisation prefers darkness. Fruiting prefers gentle ambient light.
• Fresh air Ventilation supports healthy mushroom development.
• Clean handling Always work clean to reduce contamination risk.

Ingredients and sterilisation

Great grows start with great ingredients. We use a fourth generation blend of naturally derived components selected for consistent performance.

The mix includes millet, milo, coco coir, vermiculite and gypsum, hydrated to field capacity and sterilised in a computer controlled steam autoclave.

The result is a nutrient rich growing environment designed to support rapid colonisation and reliable fruiting.
