Cloning Cannabis Using Rockwool

How can I clone weed using rockwool

Cloning cannabis is a popular practice among growers, as it allows them to produce consistent yields of high-quality buds. One of the most effective and efficient methods for cloning cannabis is using rockwool as a substrate for rooting cannabis cuttings.

Advantages of Using Rockwool​

Rockwool has several advantages over other substrates for cloning cannabis. Firstly, it is a sterile material that is free from pests and diseases, ensuring that the cuttings have a healthy environment to root in. Secondly, rockwool is a reusable material, which means that growers can use the same cubes multiple times, making it a cost-effective option in the long run.

How to Clone Cannabis Using Rockwool​

Here are the steps to follow for cloning cannabis using rockwool:

Step 1: Prepare the Rockwool Cubes​

Start by soaking the rockwool cubes in water for a few hours to ensure that they are fully saturated. Once the cubes are fully saturated, remove them from the water and let them drain for a few minutes.

Step 2: Take the Cutting​

Take a cutting from the mother plant using a sharp, sterilized pair of scissors or a razor blade. The cutting should be about 4-6 inches long and should have at least two sets of leaves.

Step 3: Insert the Cutting into the Rockwool Cube​

Carefully insert the cutting into the rockwool cube, making sure to keep the stem of the cutting upright. Gently press the rockwool around the cutting to ensure that it is held securely in place.

Step 4: Create a Humid Environment​

Place the rockwool cube with the cutting into a propagation tray or a container with a lid. Spray the inside of the container with water to create a humid environment for the cutting to root in.

Step 5: Monitor the Cutting​

Check on the cutting regularly to ensure that it is staying hydrated and that the environment is still humid. After a few days, the cutting should start to form roots, and you can gradually reduce the humidity level in the container.


Cloning cannabis using rockwool is an effective and efficient method for producing consistent yields of high-quality buds. By following these simple steps, you can ensure that your cannabis cuttings root successfully and develop into healthy, thriving plants. With the added advantage of rockwool's sterility and reusability, this method is definitely worth considering for any cannabis grower looking to expand their operation.
