White Button Mushroom Grow Kits contain everything you need, except the water. The mushroom compost has already been prepared and inoculated with the mushroom mycelium (the fungus). All you need to do is add water and wait for the mushrooms to grow. The first mushrooms are usually ready to be picked within 3-5 weeks of starting the kit. Enjoy!

The white button mushroom is the most widely grown mushroom in Australia. The caps of the mushrooms in the button stage are usually 25mm – 75 mm in diameter, but if left to mature and open, the caps can reach a size of 100mm – 175mm in diameter.

This mushroom variety can be prepared in many different ways, which makes it very popular. Our kits grow mushrooms with ease and are very productive. Crops grow back every 10-14 days until the mushroom kit uses up all its nutrients. Approximately 1.5kg of mushrooms grow in our kit during the 3-month period.

Disclaimer: (Shelf life and Storage)

This mushroom kit is designed to be started immediately when ready. A short delay of a week or two is OK, but a delay of a month or more is too long and not a good idea. It may still grow, but fewer mushrooms will be produced the longer you wait. If you wish to delay starting your kit for a few weeks, store the kit below in as cool a location as possible. It's especially risky to store away kits in warm climates like QLD or during the Summer and Spring, and is strongly discouraged.

ADD HERB SEEDS! See Below! Grow herb seeds from a used mushroom grow kit once you're done harvesting mushrooms from it. Used kits make great fertile pots for growing herbs.

Growing Tips. Follow these three easy steps.

Keep the kit out of direct sunlight. A wardrobe, a garage, or a laundry is a good spot.

Step 1. Open the box. If the compost looks brown, close the kit and leave it for a week or more. Once the compost is frosty white, continue to Step 2.

Step 2. Open the plastic and evenly spread the casing over the compost, leaving it loose and fluffy. Leave the kit open.

Step 3. Every 2-3 days mist with water. After two to three weeks, mushrooms will begin to form. Twist each mushroom out, removing any remaining stump. Fill in holes with surrounding peat moss.

Frequently Asked Questions:

Q. How many kilograms of mushrooms can I expect these kits to yield?

A. According to the manufacturer, these kits usually produce about 1.5 to 2kg (16/5/14)

Q. Are these mushroom kits organic?

A. After calling the manufacturer, I was told the following. The main part of the kit (the large bag) that includes the compost and mushroom spawns is actually organic, but it has not been certified as such. The second smaller bag included in the mushroom kit (ie bag of peat) is not certified organic; however, the bag of peat is just pure peat taken straight from the ground with nothing added, and so is totally natural.

Q. Can mushrooms be grown in summer?

A. In theory, you can grow mushrooms in summer, as long as you can keep the mushrooms cooler than 24 degrees most of the time and always under 30 degrees. Since this can be difficult, we generally do not recommend growing mushrooms during summer, especially if you are in a part of Australia with a warmer climate.

Q. Can I grow mushrooms from the same mushroom growing kit multiple times?

A. Yes, according to the manufacturer, " Most kits produce two very large crops of mushrooms and then several smaller fruiting"

Q. What is the name of the spawn used in these white button mushroom kits?

A. According to the manufacturer, the spawn used is called Agaricus Bisporus (14/7/17)

Q. What is the shelf-life of the Mushroom Grow Kits?

A. This kit is designed to be started immediately; a short delay of a week or two is OK, a delay of a month or more is too long and not a good idea. It may still grow, but fewer mushrooms will be produced the longer you wait. If you wish to delay starting your kit for a few weeks, store the kit below in a cool location as possible.
