Even it can last for up to half a decade too. Again, it depends upon the storage skills and conditions that you provide.  

Keep in mind that as the weed seed gets older, its germination rate decreases accordingly. Therefore, it is also necessary for the grower to use the seed as immediately as possible to get the most out of it.

If you protect your seeds from air, humidity, and extra heat or temperature then surely, they can last for a longer time. Ideal conditions of storing weed seeds include keeping seeds at room temperature, protecting them from the air, moisture, and other issues. 

Factors Affecting Seed Quality’s Lasting Time 

There are many factors when it comes to maintaining seed quality for a longer time. Starting from the store where you buy your seeds, if the store has sent the seeds in a well-packed manner without any damage then the chances are high that it will last longer with the same quality. 

However, on the other hand, when the seed package comes to the grower’s hand then it becomes his responsibility to make sure seeds are not affected by some major factors in case of preserving them for a longer time. 

#1. Heat or Temperature

Even for growing weed, the temperature is one of the crucial factors. 

However, when it comes to storing seeds then the temperature range must be maintained well. The cooler the location of storage is the better it will preserve seeds until your seeds don’t get freeze. 

The ideal temperature range of the storage location must be around 40-degree Fahrenheit to 45-degree Fahrenheit. (Approximately 6 to 8 degrees Celsius) 

High temperature degrades the lifespan of weed seeds and hence you must make sure that the temperature of the location where you store seeds doesn’t exceed the limit. 

#2. Humidity 

Humidity triggers the seeds to germinate

Hence while storing weed seeds for a longer time, you are supposed to keep the humidity level in control. That is why a dry location is preferred ideally. 

As humidity makes the seed sprout and spread its root out, therefore, the humidity level should be around 5%. You cannot allow the moisture level to exceed because it might lead to the germination of seeds

#3. Light

Light triggers your seeds to grow just like other factors. 

Hence make sure you avoid your seeds from the direct sunlight. Moreover, direct lighting can damage the outer layer of your weed seeds. Therefore, to keep the marijuana seeds preserved for a longer period in the same quality, one needs to protect them from the lighting as well. In short, keep your seeds in a darker place.

How to Know if Weed Seeds are Healthy?

There are several ways to check the quality of weed seeds. However, you can check from these factors, which are more likely to tell the quality of seeds with a closer approach.

Especially the brown shade. 

However, some seeds even might differ in color. Apart from this, viable weed seeds have strips or patches as well. 

Although white or green colored weed seeds are more likely to be immature. 

#2. Outer shell

The outer shell of the seed tells a lot about the quality. 

Generally, a harder shell with a waxy coating is of better quality. Whereas the seeds which can easily get squeezed or cracked with your fingers then most probably they are not of good quality.
