What humidity level is ideal for germinating cannabis seeds? I understand too high or too low can be detrimental to the process.

One answer “What is the ideal humidity for germinating cannabis seeds?

  1. When it comes to germinating cannabis seeds it is important to get the humidity levels just right. Too much or too little humidity can be detrimental to the germination process. You want the humidity to be high enough to keep the environment moist and to create ideal conditions, but not so high that the environment overly promotes bacterial and fungal growth.

    The ideal humidity level for germinating cannabis seeds is between 70-80%. This is a level of humidity that allows the seed to open and allow the humidity to soak into the cell walls. This level of moisture helps initiate the germination process while at the same time avoids an over abundance of moisture, which can be harmful to the seedlings.

    In order to maintain the optimum humidity level, you will need a humidity dome or a mini greenhouse type setup. While you won’t need a fancy or expensive setup with ventilation, it will help to keep your seedlings healthy and growing. It is also important that you check the temperature in the germination chamber regularly and maintain the air temperature between 70-80°F or the seeds may not germinate or may become susceptible to disease.

    When the seedlings have emerged from the soil and have started to show healthy growth, it is important that you start lowering the humidity to a lower level. Around 60-70% humidity is ideal for the vegetative state of the plant, as this is a level of humidity that will not promote too much bacterial and fungal growth, but will still offer enough moisture so that your plant will not suffer from dehydration. If the humidity is too low, the plant may become stressed, which may lead to slowed growth and other problems.

    It should also be noted that you may need to adjust your humidity levels during different stages of growth and cultivation. For example, during the flowering stage, your humidity levels should be between 40-50% to prevent too much moisture from damaging your buds.

    In conclusion, when it comes to germinating cannabis seeds, it is important that you maintain the ideal level of humidity which is 70-80% throughout the germination process. After the seedlings have emerged, you will want to lower the humidity to 60-70% during the vegetative stage and to 40-50% during the flowering stage. This will help ensure that your plants have the moisture they need to grow and thrive without being subject to too much or too little humidity.
