Here're features and tips for a perfect harvest. >> Read the article! When it comes to seeds, most people want them to start growing as soon as possible. Here are some tips on how to speed up seed germination!
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 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 called the taproot. Then, the cotyledon leaves emerge from the ground with their respective stem from inside the seed shell, seeking the light.
If you want to keep the seeds 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 good conservation of the seeds and prevents major germination problems in the future. On the contrary, the seeds will germinate easily and quickly if you preserve them in this way.
Step by step guide to germinating seeds in winter
1- First 24 hours: You can let the seeds rest in a glass of water. Make sure the ambient temperature of the place does not drop below 15ºC or 59ºF.
2- Second, take the seeds and put them on a damp napkin in an airtight plastic container that 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 which some growers prefer.
What does the seed need to germinate?
You may already understand what you need to be able to germinate your cannabis seeds in a great way. However, we are going to leave you with a 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. In a few days, this allows the hormones to be activated and send enough signals to produce the main root. 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. You must be careful because too much water deprives the seed of oxygen, reducing its quality, or damaging it completely. On the other hand, when the seeds are fragile and they are germinated and they suffer water stress (excess water), the growth of the seedlings is weaker.
Generally speaking, pot seeds germinate with temperatures of 70 ° F to 90 ° F (21 ° C to 32 ° C) and grow best at 78 ° F (26 ° C). Temperatures below 21 ° C (70 ° F) and 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 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.
The best strain for growing in winter
Now you know the main tips to germinate your weed seeds in winter, so you are ready to start growing your own cannabis plants. We will leave you with the best strains that you can have in your garden during the winter temperatures. We made this list thinking about the level of difficulty of the plants, how heavy their harvests are, their aromas and flavors, as well as the power of their buds.
We put Gorilla G4 on this list because it meets the requirements to be grown indoors during winter. In the first place, it is a mostly sativa variety that produces heavy indoor yields of 500gr – 600gr/m2 and is ready to be harvested in a period of 9-10 weeks of flowering.
The spicy pine and sweet flavors such as cherry are accompanied by its power that reaches 27% THC. These combine in a great way with the effects of this variety that are euphoric, super energetic, and happy with a lot of laughter and also relaxed in terms body effects.
This wonderful variety that we baptize as Cafe Racer is a favorite of growers and followers of Blimburn Seeds as it stands out for being a very great producer of buds with indoor yields from 350gr – 450gr/m2 in a relatively short time of only 70 – 75 days of flowering indoors.
Also, it stands out for the deliciousness of the flowers that produce citrus flavors of grapes and earth, a combination that permeates the palate and that is also released with the smoke in each puff. The potency of this variety can reach 27% THC, causing effects of creative moments with laughter and joy. If you go beyond the limits, you will feel a bearable body relaxation.
Black Domina Fast Version
Black Domina Fast Version should undoubtedly be on this list because it has mostly indica genetics with ultra fast flowering, taking only 6 – 8 weeks which is very beneficial for indoor winterizers. The harvests are abundant with 350gr – 450gr/m2 of buds indoors, a non-depreciable quantity, even more so if you are a fan of indica genetics.
Its effect is absolutely relaxing, perfect for smoking after a long day of work. This strain has a potency that ranges from 11% – 18% THC. The flavors are delicious as they have fruity notes with spicy touches and earthy fragrances.
Tips for growing indoors in winter
Here, the most advisable thing is to grow completely indoors. If you try to do a mixed culture, that is, that the plant grows with natural light and adding indoor lighting, be warned that your cultivation could be a failure because the plant will produce much fewer flowers and also its structural development will be less. Due to that, it is best to have an indoor space where the plants can develop with growth power and then move on to an abundant flowering.
Taking into account the above, we are going to share some tips for successful cultivation in winter. First, the temperature is essential when growing cannabis, especially in winter, so we recommend daytime temperatures of 24-30 °C (75-86 °F). However, at night, the optimum temperatures are between 18-22 °C (64-72 °F).
As a good grower, try to avoid temperatures below the range indicated above and also ensure that the changes in indoor temperatures between day and night are not so abrupt in order to avoid any type of stress to the plants.
It is good to point out that temperature changes cause the plants to make longer and more spaced internodes during the first weeks of flowering.
On the contrary, if the temperature difference between day and night is the minimal during the first 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. These bulbs emit heat, causing the low temperatures inside to decrease. This trick is widely used by old-fashioned gardeners 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.
To maintain proper temperatures, we recommend that you use a heater during the day if the temperature drops beyond the ideal range of 18-22 °C (64-72 °F). The above, you can keep controlled with a digital thermometer which will indicate the fluctuations in the crop. If you use LED lighting, the best thing you can do is keep a heater on for a longer time in order to stabilize temperatures as these emit much less heat.
In winter, there is a tendency for low temperatures to increase humidity. For the same reason, mold and other fungi can appear and damage your harvest completely. Make sure to follow our advice and use heaters and the humidity meter. If the humidity problem is very intense, a dehumidifier is needed to lower humidity levels.
There is the possibility that your growing area will be drier in winter as it is for many other growers. If the humidity is too low in winter and that is felt in the grow room, your plants can be affected in their growth because weed plants need a relative humidity of 55% to 60% in growth. In flowering, the humidity should be between 40% to 50% as the ideal maximum.
In short, you already know how to germinate the seeds in winter and we have also shared some tips on how to grow at this time of year so that you will have excellent harvests and a great experience growing. Do not forget that if you have any questions or concerns, you can leave it in the comments and our expert team will give you the advice you need.

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.
PSYCHO XXL AUTOMIX
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.

How to Speed Up Seed Germination During Winter and Spring
If you live in a colder part of the nation and are an avid gardener, you’re probably champing at the bit to get some seeds in the ground. If you have a greenhouse, that might only be a few months away. If you’re a gardener in a colder state like Colorado, you’re going to have longer to wait. And no matter how long your growing season is, you’re likely to want to get to harvest faster once you plant your seeds. Which leads to a topic that often comes up here at our nursery supply company: how to speed up seed germination.
It’s a question that home gardeners and nursery suppliers have been asking for a very long time. While genetic engineering can help a plant grow faster, there are some aspects of speeding up seed germination that you can control. Let’s take a look at ways that you can get those seed popping faster.
Soak Them In Water
There’s not much easier advice than this! All you have to do is pre-soak the seeds in hot tap water for 24 hours. The water penetrates the seed coat and allows the insides of the plant to break from the seed more easily. Usually this occurs naturally in the soil, but it can take a much longer time.
The only thing you have to be careful of is letting the seeds soak for too long. Any longer than 24 hours and they could start to rot even after you put them in soil.
Scarification is another physical means of speeding up seed germination. The purpose of a seed is to protect what’s inside and then provide initial nutrition to the plant. Because of this, the seed coat is quite hard and fairly good at protecting its interior. Scarring the seeds will remove a bit of this seed coat in order to let water in, which starts the germination process.
There are a couple of ways that you can scar a seed before putting in a ground. If you only have a few that you’re planting, you can take a knife and knick each seed, or scrape each with a bit of sandpaper. But that can get quite tedious if you’re planting hundreds of seeds, so you can speed up the process by shaking them in a jar with a piece of sandpaper.
Seed stratification is the process of tricking a seed into germination earlier than it would when it’s out in the wild. Stratification is often used for wildflowers that have a very hard outer coat on their seeds. This coat prevents the seeds from opening too early in the wild if there’s a particularly warm February day.
Seed stratification is necessary for plants that are expecting to overwinter in the ground. But if you get your seeds in the mail in March, you don’t want to have to wait another entire year before you can enjoy them. Seed stratification involves putting seeds in a moist, soil-filled bag for a time, usually 10 days to three months. This “tells” the seeds that they are cold, and that they can go ahead and wake up and start germinating. This process is especially good for our nursery customers who need full plants to sell to customers by April.
If you get your seeds in the fall and can actually make use of the natural cold outside, you can overwinter them in your garden. The problem with this is recovering the seeds later, because locating them can be difficult. The best way to find this is the put them in pots and bury the pots themselves, then dig them up and transfer to them wherever you want them when they start to sprout.
Keep Them Warm
No matter the kind of plants you are using, there’s one thing that most of just love: warmth. Keeping seeds warm tells them that the summer has arrived. Of course, that’s the purpose of most greenhouses. If you don’t have a greenhouse, keep the seeds in a south-facing window. You can even use something like a seedling heating mat that warms the seeds in their pots.
Don’t Forget to Harden Them Off
Plants that are started indoor have it pretty easy. After all, you soaked the seeds and scarred them so that the plant itself could emerge. Then you told them that winter was over and warmed them up considerably!
Since they didn’t have to work hard in order to get out of the seeds, seedlings haven’t been hardened by the world yet. They aren’t used to being cold or being whipped around by the wind, so seedlings that have been raised indoors are more likely to die than those that have been grown directly in the garden, even if they look identical.
Hardening plants is easy. Just take them outside in Spring for a couple of hours each day, then a bit longer each day after that. Eventually the wind will “harden” them to the wind and cold, at which point you’ll be able to plant them in the ground. Just don’t forget about them and leave them out overnight during their first day, or all of the work you did up above will be for nothing!
Then Come Back For Your Gardening Tool!
Of course, seed germination is on the first step to a healthy plant. Once your plants are growing in the garden, you’ll need to take care of them with the best garden hand tool around. Find them right here, and happy planting!
