Compost Tea recipe for Cannabis

Compost tea is a liquid solution made by steeping compost in water. It can be used to provide plants with a variety of beneficial microorganisms and nutrients, making it an effective way to boost the health and yield of cannabis plants. Here’s a basic recipe for making compost tea:

Easy DIY Compost Tea Recipe

Non-chlorinated/filtered or rainwaterEnough to fill a 5-gallon bucket
Organic Compost2 cups
Worm Castings1/2 cup
Blackstrap molasses1 Tablespoon
Liquid Kelp Fertilizer1 Tablespoon
Liquid Fish Fertilizer1 Tablespoon
  1. Gather your materials: You will need a large container (a 5-gallon bucket works well), a compost aerator (a small aquarium pump with an air stone will work), a fine mesh bag or cheesecloth, and high-quality compost.
  2. Fill the container with water: Fill the container with water and adjust the pH to between 6.0-7.0. You can use a pH test kit to measure the pH level.
  3. Add the compost and other ingredients: Place the compost in the mesh bag or cheesecloth and lower it into the water.
  4. Aerate the tea: Use the aquarium air pump to add oxygen to the water. This will help to activate the microorganisms in the compost. Aerate the tea for 24-48 hours.
  5. Strain the tea: After 24-48 hours, remove the mesh bag or cheesecloth from the container and strain out any solids. The liquid that remains is your compost tea.
  6. Apply the tea to your plants: The tea can be applied as a foliar spray or as a soil drench. It can be used at any stage of growth but is particularly beneficial during the vegetative stage.

Note: It’s important to use high-quality, well-aged compost, as fresh or immature compost may contain pathogens that can harm your plants. Also, be aware that the teas should be used the same day, as it doesn’t have a long shelf life.
