FAQ´s

Yes, the sale and purchase of seeds is generally allowed on Spanish territory.

In Positronics Seeds we only sell cannabis seeds for collection, study and self-cultivation in countries where self-cultivation is permitted. Misuse of these seeds can lead to conflicts with the law in certain countries.

So we recommend that, in order to avoid possible disagreements with the law, you check the national and local laws in your country.

The cannabis seed can be classified according to their dependence on photoperiods, their sex or their THC and CBD levels. Taking these factors into account we can differentiate:

Regular seeds: are seeds capable of germinating both male and female plants. The males are used to pollinate the females so that the females produce the seeds to create new plants. This type of marijuana seeds are used by growers who breed their own hybrids.

Feminised seeds: are seeds that have been genetically modified to germinate only female plants, the ones that produce the prized flowers. If you don't want to worry too much about removing the male plants and instead want to get the best yields of buds, always choose feminised seeds.

Autoflowering seeds: are seeds that change their state independently of the environment. Once they have been growing for a few weeks, they will enter the flowering phase immediately. They are the best if you are starting out in this world and want to gain experience or if you have limited time and resources.

CBD seeds: these seeds are characterised by a higher level of CBD than the usual ones, which is why they have more relaxing and anti-stress effects. In creating them, we have tried to reduce the THC level as much as possible so that they can be used for medicinal purposes.

All cannabis seeds from Positronics Seeds are of the best quality. If you can't decide between varieties that you want to try for the first time or you doubt which one to choose for convenience or other factors, be guided by the characteristics of each one of them that appear in the descriptions and by the filter in which you can search for specific characteristics.

You can also contact our customer service to solve all your doubts and find the seed that best suits your needs.

The shelf life of the seeds will depend on several factors, but if you preserve them correctly and as we recommend, they can be kept in good condition for many years.

Seeds should be stored in stable conditions of both temperature and humidity, as well as requiring darkness. If this is the case, you will be able to germinate your seeds after a few years, although there may be a slight decrease in production.

From Positronics Seeds we would like to recommend you the best way to preserve our seeds so that you can germinate them in the future.

To do this, you will need to store the seeds, together with the original packaging that protects them, in a place with the right humidity and temperature conditions. Store them in a refrigerated area with a temperature of approximately 4-8 °C.

Also, keep them away from light, humidity and temperature changes. This way you will avoid any kind of deterioration and you will be able to use them whenever you want.

When germinating cannabis seeds you need to take into account factors such as heat, humidity and darkness. If your seeds are in the right conditions and with the right humidity, the taproot will start to grow within 12-36 hours.

The best methods for germinating cannabis seeds are:

Water glass method: The easiest way is to fill a glass half full of water and put the seeds in it, with the water temperature around 22 °C. Within 3-5 days you will see the white tips sprout from the initial root.

The napkin method: the most popular, take absorbent paper (kitchen paper) and moisten it, place the seeds separately from each other and cover them with another piece of absorbent paper on top. The paper should be damp, not soaked, and make sure that it does not dry out in the high temperatures. Once the roots have grown to 2-3 mm, you can transfer the seeds to pots.

Method on land: If you decide to germinate your seed in soil directly, you will avoid having to move it at its most fragile stage. We recommend that you fill the pots with soil, soak them with water and make holes about 10-15 mm deep. Place each seed in a hole and cover them without compressing the soil. After 4-10 days you will see the plant sprout.
