High humidity can trigger fungi to grow on your seeds. If your seeds get exposed to light or rapid changes in temperature it will trigger them to use up their nutrient stores before they ever see soil, meaning they won’t have the nutrients they need to germinate.
When storing seed you want to provide optimal conditions to ensure they are still good until you’re ready to sprout them.
As we’re dealing with nature, you need to keep certain conditions or this can have an impact. Even though seeds have a hard shell and are fairly robust, you should have the following points in mind to avoid any kind of problems in the future.
6. Storing Seeds For Years
If you’ve ever germinated cannabis seeds before, then you know that light is an important factor when it comes to the probability of the seed germinating or not. If your seeds are exposed to light for too long they may end up germinating before you’re ready to plant them.
Before talking about how to store seeds we need to remember you that your cannabis seeds are alive. Before they germinate they are kind of in a state of hibernation, and like all living things, they can die.
Usually, the package they come in is light-proof and water-proof, as long as you leave them in a relatively cool place like a drawer or something similar they will be good.
This obviously depends on your climate as there are places that have incredibly high humidity and others that are quite dry, which can directly impact how you have to store your seeds.
However, humidity tends to fluctuate inside a fridge, so it’s recommended that you include desiccant in your container. It is also recommended that you store your seed container toward the back of the fridge, where the least moisture is present.
While not as important as the other factors, restricting your seed’s access to oxygen is also a good idea. Doing so can reduce or prevent seed respiration, which, in turn, can prevent premature germination.
Sealing your seed bags and containers is crucial to protecting your seeds from the elements. If your seeds came from a seedbank that vacuum-seals their seeds with silica packs, it may be OK to just store your leftover seeds like that (just make sure to protect them from light). However, if your seeds are scattered, and if you insist on storing them in bags, it may be a good idea to invest in a vacuum-sealer.
Storage Containers And Humidity Control
Not only must you provide ideal environmental conditions for your seeds, you must also maintain them. As such, it is never advisable to open your seed container for any reason other than to plant your seeds. Apart from potentially exposing them to threats such as pests and bacteria, fluctuations in temperature or humidity can also be detrimental to the health and longevity of your seeds in general.
Freezing your seeds for long-term storage is also a possibility. However, it is believed that doing so may actually damage your seeds rather than protect them. Some growers even believe that freezing damages the living cells inside of cannabis seeds. Special laboratory equipment can be used to carefully lower the temperature of the seeds in order to prepare them for long-term freezing; however, most growers lack the necessary equipment to execute this process correctly. As such, while freezing may be an option for some growers, it really isn’t for most.
If you are planning on storing your seeds for longer than this, you should consider a refrigerator. Refrigerators are great for keeping your seeds at the low temperatures they require. Moreover, most of the time, fridges are also pretty dark and dry.
Many growers eventually find themselves in situations where, for one reason or another, they are required to store cannabis seeds. In regions where cannabis is illegal, growers will inevitably find themselves stockpiling seeds. And even in regions where it is legal, large-scale growers typically buy seeds in bulk, making some storage necessary. By properly storing cannabis seeds, growers are looking out for the well-being of their future crops.
