What are Mushroom Grow Kits?

Mushroom grow kits are complete Mushroom Cultivation Systems that come with everything you need to start growing mushrooms at home. These kits include a Mushroom Spawn, Substrate, and Mushroom Grow Box. Mushroom Spawn is the active ingredient in these kits and is used to inoculate the substrate. The substrate is a medium that mushrooms use for food and to grow. The Mushroom Grow Box is specially designed to provide the ideal environment for mushroom cultivation.

How do Mushroom Grow Kits Work?

Mushroom cultivation with mushroom kits is a simple and straightforward process. Mushroom Spawn is initially added to the substrate in the Mushroom Grow Box,
where it will colonise and begin to grow mushrooms.

As the Mushroom Spawn grows, it releases enzymes that break down the substrate into nutrients that the mushrooms can use. Once the Mushroom Spawn has fully
grown, it will start producing mushrooms, which can be removed from the Mushroom Grow Box and enjoyed or used in cooking.

Common Mushroom Species Compatible with Mushroom Kits

  • Pink, White Yellow Oyster Mushrooms
  • Shiitake Mushrooms
  • Reishi Mushrooms
  • Lions Mane Mushrooms
  • Sword Belt Mushrooms

How long until my first flush of mushrooms?

Again, the answer to this question can vary depending on a variety of factors. In general, you can expect your first flush of mushrooms to appear within 1-2 weeks of
starting your kit.

The amount of time it takes for a mushroom growing kit to produce mushrooms can also vary on the type of mushroom you are growing and the environmental conditions in your grow space also play a role in how quickly your mushrooms mature.

That said, most mushroom species will be ready to harvest within 2-4 weeks after initiating fruiting. Once your first flush of mushrooms is harvested, subsequent flushes
may come even faster, with some growers reporting harvests every 2-3 days!

Average fruiting times are also listed on the box of the Grow Kit and vary between species. Oyster mushrooms are by far the fastest-growing, in just 7-14 days, while
Lion’s Mane mushrooms can take up to 14-21 days.

If you grow multiple varieties of mushrooms you will notice that the Pink Oyster Kit produces mushrooms much faster-this is completely normal and your other mushroom kits won’t be too far behind.

Let’s get growing!

Mushroom growing kits are a great way to start mushroom cultivation at home. By doing your research and selecting a kit that is best suited for your needs, you can increase your chances of success when growing mushrooms. Additionally, it is important to remember proper care and storage techniques to ensure that your mushrooms
stay fresh and ready to use.

By following these tips, you can enjoy delicious homegrown mushrooms in no time!
