The temperature for short-term seed storage should ideally be between 32°F (0°C) and 41°F (5°C). This range helps to maintain seed viability and minimize any deterioration during storage.
So let us investigate more
Short-term seed storage plays a crucial role in preserving seed viability and preventing deterioration before the seeds are utilized for germination or further use. The temperature at which seeds are stored is a critical factor that directly affects their quality and longevity.
According to scientific recommendations, the ideal temperature range for short-term seed storage is between 32°F (0°C) and 41°F (5°C). This specific temperature range provides optimal conditions for seed preservation and helps to maintain their viability over an extended period. Storing seeds within this temperature range helps to slow down natural aging processes, reduces metabolic activity, and minimizes the risk of damage or degradation.
Famous botanist and horticulturist Liberty Hyde Bailey remarked, “The storage of seeds is the storage of the seeds of life, and hence wisdom.” This quote underlines the profound importance of seed storage and emphasizes the need for proper temperature control to ensure successful conservation.
Interesting Facts about Short-Term Seed Storage:
-
The concept of seed storage is not a modern practice but dates back thousands of years. Ancient civilizations, such as the Egyptians and Greeks, were known to store seeds to ensure future crop production.
-
Seed banks, also known as gene banks or seed repositories, are vital institutions that store and preserve seeds from various plant species. These institutions contribute significantly to the conservation of genetic diversity and safeguarding of plant species.
-
Seeds’ ability to survive long periods of storage depends on factors like seed type, moisture content, storage temperature, and duration. Short-term storage provides a temporary solution until the seeds can be utilized, while long-term storage aims to preserve seeds for extended periods, sometimes even hundreds of years.
-
To maintain optimal conditions during seed storage, it is essential to control both temperature and humidity levels. Relative humidity is typically maintained between 30% and 40% to prevent excessive moisture loss or uptake, which can negatively impact seed viability.
-
Certain species have specific storage requirements. For example, some seeds require stratification, a process in which they are exposed to a specific temperature and moisture regime to break dormancy and promote germination. These species may have different temperature requirements during storage than other seeds.
In summary, maintaining the appropriate temperature range for short-term seed storage, ideally between 32°F (0°C) and 41°F (5°C), is crucial for ensuring seed viability and minimizing deterioration. As Liberty Hyde Bailey wisely articulated, seed storage encompasses the preservation of life and represents our wisdom in conserving the genetic potential of plant species.

In this video, the speaker shares three steps to store and maintain the freshness of seeds for up to five years. The first step is to keep the seeds cold and dry, which can be achieved by storing them in ziplock bags in the refrigerator or freezer. The second step is to protect the seeds from light by keeping them in a dark environment. Lastly, the speaker emphasizes the importance of saving seeds for the next planting season to continue the cycle. These methods are applicable to all types of seeds and are particularly beneficial for preserving rare or difficult-to-find seeds.
There are other opinions on the Internet
The ideal storage temperature for seeds is 35-40°F with a relative humidity of less than 40%. Most refrigerators hold a temperature of about 40°F but have high relative humidity. Seeds stored in a refrigerator should be kept in containers that have a good seal to keep the humidity levels low.
The ideal storage temperature for seeds is 35-40°F with a relative humidity of less than 40%. Do not store seed in areas that have high temperatures (greater than 70°F) or where humidity values are greater than 60%. Most refrigerators hold a temperature of about 40°F but have high relative humidity. To maintain low moisture levels, seeds should be retained in containers with tight seals and kept in freezers.

Seeds should be stored at a temperature of 35 to 40 °F and a relative humidity of under 40%. In most freezers, the temperature stays around 40°F, although the relative humidity is considerable. To maintain low moisture levels, seeds should indeed be retained in containers with tight seals and kept in freezers.

How do you store seeds short term?
Short-term storage
As mentioned above, seed can be packaged in boxes or bags; however, it is more desirable to pack the seed in air-tight containers if storage is to take place at room temperature, to maintain a constant humidity and, if need be, to protect it from insects and other pests.
What conditions are the best for storing seeds for a shorter period of time?
If you cannot store your seeds somewhere that is around the optimal 40 degrees Fahrenheit, storing seeds in a cool, dark place that stays below 55-60 degrees Fahrenheit will work sufficiently well for many seed types, for a shorter amount of time.
Can I store seeds in a cold garage?
In reply to that: Sometimes, an unheated garage or shed is a good place. As long as your seeds have been able to dry completely, they can freeze without a lot of damage. Since changes of temperature are gradual outdoors, there is less danger of condensation, and winter air tends to keep the seeds dry anyway.
What are the conditions for seed storage?
The answer is: Keep them in dry and cool place to extend their viability. Seeds easily re-absorb moisture. To maintain dryness, keep seeds in air-tight containers like tin cans or glass jars with tight fitting lids. Put in some moisture absorbing material.
What is a good temperature for seed storage?
As a response to this: A simplified rule for success is that the sum of the temperature (°F) and percent relative humidity should be less than 100. The actual storage life will depend upon the viability and moisture content of the seed when initially placed in storage, the specific variety, and the conditions of the storage environment.
How long can seeds last in storage?
Response: Some seeds will remain viable in storage for several years if stored under optimal conditions — namely, low humidity and low temperature (42°F or 5.6°C). A simplified rule for success is that the sum of the temperature (°F) and percent relative humidity should be less than 100.
How does temperature affect seed viability?
The longevity of seeds depends on initial seed quality, moisture content and temperature during storage. In general, low moisture content and low temperature reduce the loss of seed viability. Different combinations of moisture content and temperature can be used to prolong seed viability during storage.
Do you need a high moisture content for seed storage?
Response will be: Using the correct seed moisture content for sealed storage is very critical as seed sealed with too high a moisture content may lose viability more rapidly than air-dry seed in open storage at the same temperature.

How do temperature and humidity affect the shelf life of seeds?
Seed moisture and storage temperatures affect the shelf-life of seeds in long-term storage. Fluctuations in temperature and humidity during the storage period can be harmful to the seed, reducing the storage time and seed quality. 4 Avoid storing seed at temperatures above 70°F (21°C) and humidity levels above 60%.
Do you need a high moisture content for seed storage?
Response: Using the correct seed moisture content for sealed storage is very critical as seed sealed with too high a moisture content may lose viability more rapidly than air-dry seed in open storage at the same temperature.
