cannabis seed storage containers

If, for example, you live in an area with very warm daytime temperatures and cool nights, try to protect your seeds from these changes and don’t store them outside in a shed or garage.

Ideally, you want to store your seeds in a cool, dark, and dry place. Whenever possible, keep your seeds in their original packaging. At Royal Queen Seeds, we’ve specially designed our packaging to protect our seeds until you’re ready to plant them.

EFFECTS OF HUMIDITY ON CANNABIS SEEDS

Humidity is easily one of the biggest threats to your seeds. Here is how different levels of humidity (% relative humidity) affect your cannabis seeds:

Ziplock bags, for example, are great because you can remove all the air from them to create an almost vacuum-sealed container for your seeds. Once vacuum-sealed, put your bag inside a dark plastic bag or dark container to protect your seeds from your fridge light.

Many people forget this, but it’s true—your cannabis seeds are living organisms. Before they germinate, however, they are in a state of rest (much like some animals when they hibernate). And like all living things, seeds can die. When storing your seeds, you’ll want to give them the optimal conditions to ensure they hold through until you’re ready to germinate and plant them.

Labelling the strains you have is even more vital if you cannot see the seeds. This can be the case if, for example, you follow the advice of some growers, who instruct more inexperienced growers to store their seeds in analogue film tubes. In cases like this you can simply stick a small label on it and jot down with a pencil the name of the strain in each tube, which should be placed, in turn, inside a piece of Tupperware to prevent its contents from deteriorating.

Another threat that can ruin all your efforts are insects. Just one in your container is enough to render all the seeds inside useless. To prevent this it is advisable to spread diatomaceous earth where you store them. D.E. is a kind of sand with a fossilised algae base. It is inert and non-toxic, and functions as an invaluable natural insecticide. If you keep your seeds in your fridge with other foods, this will not be a good place to use this type of substrate. However, if you have a refrigerator just for this purpose, or a simple closet, you will be able to use this trick.

To ensure this we place small pearls of silica gel inside the tubes so that, even if the outdoor humidity rises, or the temperature varies, we can be confident that the air is completely dry inside. The cap of the Eppendorf guarantees that no humidity gets in, but the silica gel also ensures that, if any were to penetrate it by accident, it would be immediately absorbed by this material.

Labelling the different strains, essential to differentiate between them

Whether you choose to store your seeds in a refrigerator designed exclusively for their maintenance, or in a dark corner of your house, you will have to pay attention to other risks that can end up damaging them. Many experienced growers stress that seeds must be dried correctly and left under proper humidity conditions to prevent mould from appearing inside the receptacles. To keep this from occurring, in addition to drying the seeds properly, it is a good idea to always use silica gel when storing them.

To keep humidity low, it is ideal to have some sealable containers on hand. To do this, a highly recommended option is to use Eppendorf tubes, a standard piece of laboratory equipment used for the preservation of liquid samples, and the very ones in which we provide our customers with our seeds.

They are where it all begins. The care you give your cannabis seeds will determine not only how your plants grow, but also the final results of your harvest. As we are dealing with a natural product that needs to develop, the conditions under which it is stored will have an impact on their subsequent yield. Thus, though marijuana seeds are quite robust and autonomous, if you want to avoid unwanted setbacks when you plant them, you should take steps immediately after obtaining them.

You must not forget that light is another of the factors that directly impact seed germination. Therefore, you must be sure that you prevent light from shining on the seeds that you will later be planting. If exposed to light, they can lose much of their germinative power. This is why at Dinafem we place our Eppendorf tubes in opaque metal boxes, which protect the seeds from light and any possible crushing or breakage during their transportation or handling.
