How long to soak cannabis seeds?

I’ve heard that soaking cannabis seeds before planting can improve their germination rate, but I’m not sure for how long to soak them. Can you recommend a time frame for soaking?

One answer “How long to soak cannabis seeds?

  1. It’s possible for cannabis seeds to stay dormant for years and still have the ability to germinate, so it’s always a good idea to check the germination rate before planting. To help increase the chances of success, many growers recommend soaking cannabis seeds before planting, as this can help break down the tough outer seed coat and speed up the germination process.

    So how long should you soak cannabis seeds before planting? As a general guideline, soaking cannabis seeds should be done for at least 18 hours. During this time, the seeds should be kept in a temperature of around 24-27°C, as too high or too low temperatures can damage them. Most growers fill a bowl with warm water and place the seeds inside, leaving them to soak throughout the night.

    When the 18-hour soak is over, you should rinse the seeds and then store them in damp tissue paper or between two damp paper towels and place them in a warm, dark area. This location should also have a temperature of around 24-27°C, as this will ensure the seeds remain warm and ready for planting.

    It’s important to note that some cannabis seeds may require an even longer soaking time than 18 hours. In this case, it’s best to check the instructions of the seed pack to see how long they recommend soaking your seeds. Generally, cannabis seeds should never be soaked for more than 48 hours, as this can lead to them becoming waterlogged, which increases their chances of not germinating successfully.

    It’s also a good idea to perform a “float test” before planting your soaked seeds. This involves taking each seed and placing it into a cup of water. If the seed floats, it means that it has probably gone bad and should be discarded. If the seed sinks, it means that it is still good and can be planted.

    Once the seeds have been soaked for the recommended time and you have performed the “float test” and discarded any dud seeds, they’re ready to be planted. By soaking cannabis seeds before planting, you’re giving them a head start to the germination process and increasing the chances of success.
