How to Use Compost Tea in Hydroponics


Compost tea is a nutrient-rich liquid made from soaking a solution of compost in water until the nutrients leech out of the hummus. Hydroponics is the process of growing plants with a soil-less solution of nutrients and a dry mix to support the roots of the plant. Proponents of hydroponics say plants grown this way grow larger and have a better yield than plants grown in the soil. Compost tea can be mixed into the nutrients used to grow hydroponic plants for a better yield.

Step 1

Place compost into a burlap bag and close the mouth of the bag.

Step 2

Fill a 5-gallon bucket with water.

Step 3

Place the burlap bag into the bucket of water.

Step 4

Let the bag soak in the bucket for three hours so that the nutrients leech out of the compost in the bag.

Step 5

Remove bag and place compost back into the compost bin.

Step 6

Inject your compost tea solution into your hydroponic irrigation system along with your hydroponic nutrient solution once weekly at a ratio of 10 parts nutrient solution to 1 part tea.
