Risk factors for shrinkage and the topsoil drying out includes, close proximity to heat sources, ie radiators. A lack of water being sprayed onto the topsoil and draughts / dry air.

Resolving a dry topsoil.


If the topsoil is grey or containing light speckles and/or the compost is coming away from the sides it is losing hydration and his needs to be replaced.

To address this, with your spray bottle spray multiple times through the day, little and often until the topsoil is the correct colour again, then maintain this new level of hydration.

It is also important to fix any other factors, so move away from heat sources or direct sunlight. Ensure side flaps are raised up and you are not growing these above 21'c.

What to do if my topsoil is too wet?

Example of a kit that is over watered.


To address this, reduce the water and dab away excess water with paper towel. Then maintain this new level of hydration.

The mushrooms cannot grow if in contact with pooling water, so this needs to be avoided at all times. The water should be fully absorbed by the topsoil, spray only enough to keep it deep black in colour. 

If the topsoil is no longer absorbing the water, you are likely using too much.

Correct Hydration

Correct Hydration example.


The mushrooms require the correct level of hydration in order to fruit effectively. Spray bottles are best used to avoid over watering and pooling water

However if you use a spray bottle ensure you are using enough volume of water each day to ensure the topsoil remains the correct colour (deep black) and level of hydration.

The amount of water will vary upon conditions such as temperature and room humidity / draughts.
