How to germinate cannabis seeds in water?

I’ve heard that you can germinate cannabis seeds in water. Is this true? If so, what is the process and how long does it take?

One answer “How to germinate cannabis seeds in water?

  1. When it comes to cannabis cultivation, one of the most common questions that arises is whether or not you can germinate cannabis seeds in water. The answer is: Yes, you can germinate cannabis seeds in water, however, it is not the most commonly recommended method for successful germination. It is important to understand the process and the amount of time it will take to be successful.

    As with any germination process, the goal is to get the seed to absorb enough moisture so that it breaks dormancy, penetrates the outer seed coat, and begins to grow. To make this happen, cannabis seeds need a warm, moist environment. While warmth usually comes from a heat mat or grow tent, moisture can be provided in a variety of ways.

    In water germination, instead of using soil or another type of grow medium, cannabis seeds are placed into a glass of water. This environment provides a consistent temperature and moisture that the seeds require to germinate. It’s important to use only filtered or distilled water to avoid mineral build-up, and to change the water every 24 hours. The water should also have a temperature of approximately 70-90 degrees Fahrenheit to encourage successful germination.

    Once the water is ready, you can treat each seed in the following manner:

    1. Place the seed in the water and let it sink to the bottom.

    2. Carefully monitor the seed’s buoyancy.

    3. Depending on the size of the seed and the kind of shape it has, it may float, sink, grab onto the side, or stay suspended.

    4. If the seed starts to float, you may need to lightly press it down into the water until it sinks.

    5. If the seed sinks, then it is a good sign that it is taking in moisture and has begun to germinate.

    6. After 24 hours, you should check the seed for signs of germination.

    7. If the root has sprouted, you can move the seed over to soil.

    On average, it takes about 4-5 days for a cannabis seed to germinate in water. It may take longer or shorter depending on the size, shape, and quality of the seed. If the seed has not sprouted after 5 days, then it is likely that the seed is not viable or is too old to germinate.

    Overall, while you can germinate cannabis seeds in water, it is not the ideal method for successful germination. A lot of effort and time is required to ensure the seeds get the right amount of moisture and temperature, and even with all that effort, some of the seeds may still not sprout. There are other, simpler and more reliable methods, such as using soil and seed starters, that are much more commonly recommended. Germinating in water can be an interesting method to experiment with, but for a successful and reliable cannabis grow, it is always best to use one of the tried and true methods for germination.
