Cannabis seeds are the foundation of the cannabis plant’s life cycle and are the source of all its medical and other psychoactive effects. As such, it is important for growers to be aware of the potential problems that may arise if cannabis seeds sink when planted, as this could lead to poor yield and insufficient quality of cannabis. In this article, I will provide an overview of the possible reasons as to why cannabis seeds sink, likely consequences of this and tips for preventing this from happening in the future.
Reasons for Sinking Seeds
One of the primary contributors to sinking seeds is the fact that the seed coat that surrounds the seed comprises between two and five inner layers. This outer layer can be very easily damaged, weakened or even removed by causes such as temperature fluctuations, moisture levels and light exposure. All of these can contribute to cannabis seeds sinking when planted. Another possibility may occur due to the seed not being viable, either due to various seed diseases or just not receiving the right environment to induce germination.
Consequences of Sinking Seeds
The consequences of sinking cannabis seeds can be problematic for both amateur and professional growers alike. If the seed coat is damaged before planting, the seed may not germinate at all. This means that the grower will not be able to harvest any cannabis from the plant and still must bear the costs of buying new seeds. The other likely consequence of sinking seeds is the development of seedlings with poor or abnormally short root systems, which are not able to take in the proper amount of nutrients required for the plant to flourish.
When planting cannabis seeds, there are several steps that can be taken to increase the chances of having a successful crop. Firstly, maintaining consistent temperatures is key, as temperature fluctuations can weaken the seed coat and make it more likely to sink. Secondly, make sure that the levels of moisture in the soil are regulated; too much or too little can make it more likely for the seed to sink. Then, to ensure that weed seeds are given the best chance of survival, it’s important to make sure that the environment is free from contaminants. Additionally, it’s necessary to properly label and store seeds, as this minimizes the chance of them developing any kind of disease. Finally, only germinating seeds from well-reputed suppliers is paramount if you want to ensure an optimal outcome.
Managing Seed Storage
As the quality and viability of cannabis seeds significantly reduces over time, storing them correctly is of paramount importance. Storage should be undertaken in a dark and cool place to reduce light and heat exposure. Additionally, some growers opt to use a humidity control device that is designed to keep the moisture levels in the seed at an optimal level of 55%. Finally, in order to extend the life of cannabis seeds, they can be housed in an airtight container and placed in the refrigerator. This will prevent the seeds from drying out and/or absorbing any odors that could negatively impact their quality.
Fixing Damaged Seeds
Seeds that have been damaged due to light exposure, temperature fluctuations, excessive humidity or diseases can often be rectified by treats such as pre-sprouting or hot water treatment. Pre-sprouting is often done in a damp cloth kept in a warm and humid environment, and then transferred to the soil after sprouting. Hot water treatments, on the other hand, involve boiling the seeds for about 15 minutes and then transferring it to sowing trays. The water should be changed each day for a period of five days, before finally being planted.
Protection and Safety Measures
When handling cannabis seeds, it is important to always use the correct protective equipment. These include the use of safety glasses, shoe covers, and disposable latex or nitrile gloves to protect against allergens and irritants. It is also recommended to use a face mask or respirator whenever handling cannabis seeds so that if any toxins or allergens are present in the air, they will not be inhaled. In order to ensure the spread of any diseases or parasites, it is also important to regularly disinfect the growing area and dispose of any used materials properly.
Wet Temperature Conditions
Cannabis seeds exposed to wet, high temperatures can be prone to sinking and rot. To combat this, growers can opt to use cardboard or fabric grow pouches as these allow air, while still setting a barrier between the seeds and the soil. This can help to protect the seeds by preventing them from absorbing excess water, while allowing the seed to still receive essential oxygen and other gases. Additionally, using an open container like an egg carton where the seeds are lifted off the soil, can help to keep them cooler and drier.
Root Rot Prevention
Once cannabis seeds have sprouted and the seedlings have developed roots, root rotting can occur due to conditions such as too much water, high temperatures or an unclean growing area. To prevent root rot, growers can use a pasteurization process, which helps to reduce the number of fungicides in the soil. Additionally, controlling water and temperature levels, keeping the growing area clean and choosing disease-free potting soil are also key practices in preventing root rot.
