MushroomSupplies Grow Kit In-A-Bag PLUS - 5 LB

The MushroomSupplies Grow Kit In‑A‑Bag PLUS is a quick and easy solution to grow mushrooms at home or in the lab. It is enclosed in a sealed, sterilized bag, which has everything required for healthy mycelium development. Users only need to add some spores or liquid culture. This all-in-one kit eliminates much of the typical hassle and risk of contamination.

Premium Ingredients

A balanced blend of millet, coco coir, vermiculite, gypsum and composted manure is included in each PLUS bag. Millet grain offers a large surface area for mycelium, helping it to spread quickly. Coco coir and vermiculite are moisture-retaining. Adding gypsum introduces calcium and sulfur, which promote healthy mycelial networks. Composted manure adds the nutrients many mushrooms adore.

Improved Bag Design

The horizontal filter patch of the PLUS version is wider. This filter allows clean air to pass back through the bag at all stages of growth. This good airflow takes away the risk of smothering in CO2 and the risk of stalling the colonization. Featuring a self-healing port, users can inject spores without being exposed to contaminants. The bag’s robust and durable seal and lab‑quality material help ensure perfect results every time.

Easy Steps to Grow

Get the kit set up and running with these instructions.

1. Load with 10–20 mL of spores or liquid culture via the self‑healing injection port.
2. Put the bag in a dark place at room temperature (65–75°F) until the substrate is about half white.
3. Lightly shake the bag to distribute the mycelium for uniform colonization.
4. Wait until the bag has turned full white; this generally takes about 1-2 weeks.
5. Snip or poke a hole in top of bag and relocate bag to a bright place with indirect light. Mist to keep humidity high.
6. Harvest mushrooms when the caps are open and the stems are straight. Small-scale growers may harvest three times from one bag.

Harvest Yields

Each PLUS bag will yield 2.5lb of fresh mushrooms per cycle. When dried, this gives around 0.25lb of mushroom product. A two to three-flush crop is common. The first flush will typically yield the most, with subsequent flushes providing smaller, but still useful harvests. Uniform humidity and moderate temperature are the key to obtaining greater yields.

Safety and Cleanliness

MushroomSupplies employs a hospital‑grade sterilization process that ensures any unwanted microbes are put down. Every bag is sealed in cleanroom and tested with bio‑indicators to verify sterilization. Filter patch and self‑healing port work together to seal airborne bacteria and mold spores. If contamination does occur, the manufacturer warranties a free replacement which gives peace of mind to all producers.

Who Can Use This Kit

This is the all in one kit for beginners and experts alike. With the all in one design and lab quality sterility it is ideal for:

• Hobbyists: New growers seeking an easy, low-risk introduction to growing mushrooms.
• Educators: Science teachers and lab teachers who want a clean, classroom‑safe configuration.
• Small‑Scale Growers: Small business owners or chefs looking for a smaller scale production system but not yet needing a full cleanroom.
