How to Germinate Cannabis Seeds in Winter

First of all, we tell you that to germinate your cannabis seeds you will only need water, heat and air to break open to break the shell that covers them and give life to the main or primary root; they do not need hormones, fertilizers or additional additives. The sprouting of the seeds takes place without light with certain temperature ranges. Seeds that are in a healthy state germinate in 2 to 7 days.

When germination occurs, the outer protective shell of the seed opens and a small white shoot emerges, that is, the taproot. Then, the cotyledon leaves emerge from the ground, with their respective stem from inside the seed shell, seeking the light.

If the seeds that you want to keep for later cultivation, it is best to keep them in an airtight pot with a hemertic bag and in complete darkness in the area where you keep the vegetables in your fridge. This allows the good conservation of the seeds and that in the future you do not have major germination problems, on the contrary, the seeds will germinate easily and quickly if you preserve them in this way.

Step by step to germinate seeds in winter

1- First 24 hours. You can let the seeds rest in a glass with water so that the shell can speak. Make sure that the ambient temperature of the place does not drop below 15ºC, that is, 59ºF.

2- Second, take the seeds and put them on a damp napkin in an airtight plastic container, which you can put on top of a heat source such as a television or internet modem . Make sure that the napkin has a certain thickness so that the seed does not burn with the heat of the modem and try to maintain the room temperature so that the container and the seed do not suffer from sudden changes in temperature.

3- After 24 to 72 hours the seeds will germinate, try to always keep the container and the napkins moist, if you wish, as soon as you see the root come out from inside the seed, you can transfer it to the ground. In other cases, you can wait for the taproot to spread a bit more before putting it in the ground, some growers prefer that

What does the seed need to germinate?

With what we explain to you, perhaps you can already understand what you need to be able to germinate your cannabis seeds in a great way. Anyway, we are going to leave you here the list of the basic and fundamental elements to carry out the process.

A great level of water:

When you soak cannabis seeds in water it allows the moisture to penetrate the protective shell of the seed in minutes, this allows that in a few days, the hormones are activated and send enough signals to produce the main root. So the white radicle means that it is ready to go into the ground and start its cycle as a plant.

It is also good to say that some seeds need a lot of humidity to germinate or else, they do not, that you must be careful because, too much water deprives the seed of oxygen, reducing its quality, reducing it, that is, it damages it completely. On the other hand, when the seeds are fragile and they are germinated they suffer water stress (excess water), the growth of the seedlings is weaker.

Good temperature:

Generally speaking, pot seeds germinate with temperatures from 70 ° F to 90 ° F (21 ° C to 32 ° C) and grow best at 78 ° F (26 ° C) , then we say that t emperatures below 21 ° C (70 ° F) and for Above 32 ° C (90 ° F) can damage germination and low temperatures can slow germination . When you germinate cannabis seeds in high temperatures, they can be chemically affected and the result will be poor germination.

Air and oxygen:

When starting the germination process it is necessary to take into account that the seeds require fresh air at certain times to have a successful germination. For this reason, we recommend that every 4 or 5 hours you open the airtight plastic pot that you are using in order to let the air circulate as well, and if necessary we suggest that you change the wet napkins because, in some cases they tend to produce fungus. that can affect the cannabis seeds you want to germinate.

On the contrary, if the temperature difference between day and night is the minimum possible during the f irst flowering phase , this will reduce the internodal spaces in the weed plant, the maximum ideal temperature difference is 2-4 °C (3.6-7.2 °F) during the first 2-3 weeks of flowering, for the rest of the flowering period temperature changes should not exceed 10 °C (18 °F) and your plant will flourish happily.

A good way to keep the grow room at the optimum temperature is to use HPS or high pressure sodium lighting, since as these bulbs emit heat they cause the low temperatures inside to decrease, this trick is widely used by old-fashioned gardeners. school who have experience growing indoors during winter. Unlike in summer, when grown in winter producers turn on the lights at night and use the day as the night period, this allows the grower to take advantage of the warmer temperatures during the day.

Winter marijuana seeds: features and tips for a perfect harvest.

As the cold season approaches, cannabis growers tend to wonder what the winter marijuana seeds are, so they have a fair chance of harvesting them during the winter as well.

It is said that auto flower seeds are best for outdoor winter, as they have – at least partially – Ruderalis genetics. And Ruderalis cannabis reflects what the name makes us imagine: it is ‘rough’, wild, used to survive even under extreme conditions such as cold, rain and high humidity.

The belief that auto flower seeds are perfect for withstanding extreme temperatures and weather conditions is not entirely wrong, but the farmer’s final goals must also be considered. Are you only interested in a strong cannabis plants or are you looking for a good harvest? If the latter option is the right one, maybe you should not grow outdoors.

Please note that our in-depth studies are only for information. We do not advise you to grow weed seeds because, if you are in the UK, you will commit an administrative or criminal offence depending on the situation. If you currently live in a state where it is allowed to grow marijuana for personal use, then you can rest assured.

Do winter cannabis seeds have a good yield when grown outdoors?

The answer to this question is no! Marijuana plants need special conditions to develop and flourish at their best.

Although automatic cannabis strains flower not according to temperature and light conditions but according to their age (they are usually ready for harvest about 10 or 11 weeks after germination). If grown outdoors in the middle of winter they may still die or stop growing. At best, they may produce very few flowers with low THC and CBD content.

Now imagine you are a cannabis grower. After you have put all your energy into getting a beautiful plantation, winter comes to stop everything: no crops and seedlings irreparably damaged. It’s certainly not a pleasant prospect!

Growing marijuana seeds on winter is undoubtedly possible, but not outdoors. For marijuana plants to develop outdoors in the best possible way, they need favourable climatic conditions.

The perfect conditions for cannabis plants development

Marijuana doesn’t care whether it’s summer or winter. It is only essential to have the right climatic conditions for its growth. For auto flower seeds, fast growing weed seeds and feminized seeds to germinate and for the seedlings to grow well, it is essential that the following conditions are met:

  • Relative humidity: during germination, the RH should be between 60% and 80%, during the vegetative phase the RH should be between 50 and 70% and during flowering between 40 and 60% at most.
  • Temperature: the temperature should be reasonably stable, so a wide temperature range is not recommended. During the germination of cannabis seeds, the temperatures should be between 22 and 26ºC, during the vegetative phase between 21 and 29ºC and during flowering between 18 and 26ºC. The minimum values refer to night-time temperatures, which should not exceed 6-7ºC difference from daytime temperatures.
  • A good soil, well-drained, fertile and fertilized with organic nutrients.

That said, minimum temperatures should never drop below 15ºC as cannabis plants could suffer so much, stop growing and/or die. As you can imagine, it is complicated for temperatures not to fall below 15ºC in winter (unless you are in the Maldives, Hawaii or somewhere else where it is hot all year round… So I envy you!).

Besides, it is not uncommon for rainfall, frost and other situations to occur during the winter months. They will be the perfect conditions for mould and fungi development, which are very harmful to cannabis plants.

That is why growers who choose to plant cannabis seeds in winter do so Indoor or in Greenhouse.

Do winter marijuana seeds exist?

Let’s say that plants born from auto-flowering cannabis seeds and fast growing cannabis seeds are more resistant to low temperatures than seasonal plants. They come from Cannabis Ruderalis varieties crossed with Indica or Sativa. But don’t expect them to resist frost and extreme temperatures!

They may not die below 15ºC, but they will still suffer, either by stopping growing or at most producing a small number of flowers. That’s why growers prefer to grow Indoor or Greenhouse with controlled temperatures, in order not to stop during the winter season and get a good harvest.

Alternatively, if they are in a region with an extremely favourable climate, they can grow in pots and then you only have to shelter them during the evening, at night, and when the weather conditions turn bad.
