Step-by-Step Instructions: Cleaning and Disinfecting the Grow Tub

Materials Needed:

• Grow tub and its lid
• Dish soap or a mild detergent
• Warm water
• Soft cloth or sponge
• 10% bleach solution or isopropyl alcohol (70% or higher)
• Spray bottle (if using a liquid disinfectant)
• Clean towels or paper towels
• Gloves (optional, but recommended for working with bleach)


1. Preparation:

a. If you're using a bleach solution, prepare it by mixing one part bleach with nine parts water. For instance, combine 100ml of bleach with 900ml of water to make 1 liter of a 10% bleach solution.
b. Pour the solution into a spray bottle for easy application. If you're using isopropyl alcohol, ensure it's in a spray bottle.

2. Washing the Tub:

a. Begin by washing the inside and outside of the tub with warm water and a small amount of dish soap or mild detergent.
b. Using a soft cloth or sponge, scrub the tub gently, ensuring you reach all corners and crevices.
c. Rinse the tub thoroughly with clean water to remove all soap residues.

3. Washing the Lid:

a. Similarly, wash the lid with warm water and dish soap or detergent.
b. Rinse the lid thoroughly to ensure no soap residues are left.

4. Disinfecting:

a. Wearing gloves, spray the inside and outside of the tub evenly with your chosen disinfectant – either the 10% bleach solution or isopropyl alcohol.
b. Ensure the entire surface area of the tub and its lid is covered with the disinfectant. Allow it to sit for at least 10 minutes.
c. With clean towels or paper towels, wipe down the surfaces. This step helps remove any residual contaminants and ensures the tub is ready for the substrate.

5. Drying:

a. Once you've wiped down the tub and lid, leave them out to air dry. Ensure they are completely dry before adding any substrate to prevent excess moisture, which can lead to contamination.

6. Storing for Later Use:

a. If you're not using the tub immediately after cleaning, store it in a clean, dry location to prevent any contaminants from settling on its surface before use.

By ensuring your grow tub and its lid are properly cleaned and disinfected, you set the foundation for a successful mushroom cultivation process.
