What are the best cannabis seeds?

Seedstockers’ cannabis seeds stand out for their combination of key factors that ensure a high-quality cultivation and consumption experience. Here are the main characteristics that define our first-class cannabis seeds:

1. Quality genetics

Genetic stability is crucial to ensure that the resulting plants are uniform and meet the grower’s expectations. And our seeds come from well-established and proven lineages, which have been carefully crossed to improve specific traits such as potency, taste, or disease resistance.

2. High germination rate

This means that most planted seeds should sprout and become healthy seedlings. Seedstockers’ premium seeds have a germination rate of over 90%, which ensures a solid start to the growing cycle.

3. Potency and cannabinoid profile

Seedstockers’ cannabis seeds produce plants with high cannabinoid levels (especially THC and CBD) and with rich and complex terpene profiles. Not only does this contribute to the aroma and flavour of cannabis but also to its therapeutic and recreational effects, all thanks to the entourage effect.

4. Yielding capacity

Our seeds result in plants that are incredibly potent and produce a significant amount of dense and resinous flowers. These strains, selected for their high yielding potential, are especially valued by both commercial growers and amateurs.

5. Resistance and adaptability

Cannabis plants grown from Seedstockers’ seeds can better withstand pests, diseases, and adverse weather conditions. This high resistance is vital to ensure a successful harvest, especially in outdoor grows where environmental factors are harder to control.

6. Ease of cultivation

For many growers, especially beginners, it’s extremely important that the plants are easy to grow. Seedstockers’ top quality cannabis seeds are relatively easy to handle, with maintenance and care needs that aren’t too complicated.

7. Ratings and reputation

The best cannabis seeds usually come from seed banks and breeders with a solid reputation in the industry. Our multiple awards in various cannabis cups are extremely reliable indicators of seeds that meet the highest quality standards.

In short, the cannabis seeds that we offer at Seedstockers clearly combine all these factors. When choosing the right strain for you, consider your personal preferences and the specific conditions of your growing environment. Explore these options and find the perfect seed for your next grow.

How to buy cannabis seeds online​

Purchasing cannabis seeds from Seedstockers involves a simple and safe process. Our website is easy to navigate and includes detailed descriptions of each variety and flexible purchase options, ranging from 1 to 25-seed packs. We offer secure payment methods, such as via credit card or bank transfer. Additionally, Seedstockers provides discreet shipping to ensure the privacy of our customers. Before making any purchase, it is essential to verify the legality of cannabis seeds in your country or region. The laws on possession, sale, and cultivation of cannabis vary considerably from one place to another, so it is essential to know and comply with local laws to avoid any legal problems.

Seedstockers also offers excellent customer service, providing support and advice throughout the whole purchase and cultivation process, to solve any doubts or problems that may arise. Likewise, we offer tracking numbers, so you’ll be able to keep a record of your order and constantly be up to speed with the status of the shipment. This helps ensure that you receive your seeds without any problems. With the support of a good seed bank like Seedstockers, there’s no doubt your shopping experience will be fully rewarding!

How to know if your cannabis plants are male or female?

With Seedstockers, you won’t have to worry about the sex of your plants because all our seeds are feminised. This means that they are designed to produce exclusively female plants, which eliminates any concern that male plants may appear in your grow.

Female plants produce the cannabinoid-rich flowers that growers are after. In contrast, male plants don’t produce flowers which are suitable for consumption, and can pollinate females, thereby reducing the quality and quantity of the crop.

By not having to worry about removing male plants, growers can maximise the use of their grow space and ensure that each plant contributes to flower production. This results in a more efficient use of time and resources, and is especially beneficial for rookie growers who may not have experience in identifying the sex of the plants.

What’s more, Seedstockers’ seeds are usually the result of a careful breeding process that ensures the development of plants with consistent genetic characteristics. This means that growers can expect greater uniformity in their crops, both in terms of growth and cannabinoid production.

What types of cannabis seeds can you find at Seedstockers?

Our cannabis seed catalogue comprises a wide range of genetics that can easily adapt to different needs and growing preferences. The available options include:

Feminised seeds: These are also known as photo-dependent, as they depend on the changes in the light cycle to start flowering. They’re a great option for those seeking stability and consistency in their grows.

Autoflowering seeds: Automatic plants start flowering autonomously after a certain period of growth, regardless of the light cycle. This makes them ideal for growers looking for a quick and simple harvest.

Fast flowering seeds: These seeds combine the advantages of feminised seeds with a shorter flowering cycle. They’re ideal for those who want to obtain quick crops without having to compromise on quality or yield. Fast flowering seeds allow for faster crop rotation, which is beneficial to maximise the yield in a shorter period of time.

Seedstockers is proud to offer different types of seeds to meet the diverse needs of growers, providing high-quality genetics that guarantee outstanding results. Whether you prefer the stability of photo-dependent seeds, the speed of autoflowers, or the efficiency of fast flowering strains, Seedstockers always has the perfect choice for you.

Classic and modern cannabis seeds

The Seedstockers team is proud to offer classic cannabis seeds alongside more modern and avant-garde alternatives. Our selection of North American strains captures the latest trends in the world of cannabis, providing growers with access to the high-quality genetics that are all the craze on the current market. These varieties stand out for their unique taste profiles and potent effects, reflecting the best of the contemporary gene pool.

But we also recognise the importance of old-school strains. These legendary hybrids have been highly valued for decades for their exceptional and consistent features. Classic varieties that have been awarded multiple prizes in various competitions and cannabis cups around the world, and still remain a popular choice among growers and connoisseurs for their incredible reliability and performance.

At Seedstockers, we combine the best of both worlds to offer you a rich and diverse growing experience, satisfying both fans of lifelong strains and those seeking the latest innovations in cannabis genetics.

What cannabis strains are most productive?

For those growers who have just arrived in this exciting world, plants that require less maintenance and deliver fast results are ideal. Feminised or fast flowering seeds are a great option because you don’t need to identify and eliminate male plants, which saves both time and effort.

In addition, autoflowering seeds are especially rookie-friendly, as they don’t need any changes in the photoperiod to start flowering: They’re practically "programmed" to go through all stages of development without the need for additional intervention, which makes them a very attractive option for new growers.

Their short life cycle also reduces the chances of problems during cultivation. These plants tend to be smaller and more discreet, which makes them ideal for those who want to start growing in tight spaces, such as a small balcony or a compact grow tent. This simplicity and efficiency allow rookies to have a satisfying and successful experience at their first attempt.

What are the best cannabis seeds for beginners?

All our seeds are designed to deliver generous yields with high levels of THC and other cannabinoids. Having said that, feminised seeds tend to be more productive than autoflowerings due to their longer life cycle and ability to grow taller, which leads to the development of more buds.

The yielding capacity of each strain is clearly detailed in the description of every seed, with these figures being based on optimal growing conditions. It is important to keep in mind that the number of buds you can get will depend on your experience as a grower, the growing method that you choose, and, above all, the environmental conditions in which the plants grow.

By optimising these factors, you’ll be able to maximise the yielding potential of your cannabis plants and obtain impressive crops with our Seedstockers strains.

What are the ideal cannabis strains for indoor / outdoor growing?

All of Seedstockers’ genetics can be grown both indoors and outdoors, but there are certain factors that should be considered before choosing the right variety for each environment.

Indoor seeds

For indoor growing, it is best to select short flowering varieties, such as autoflowerings. The faster their flowering cycle, the fewer the chances of them developing issues such as pests, fungi, or other common problems that can be found in controlled environments. Fast flowering strains allow for several harvests in a short time, thereby optimising the available space and resources.

It is also important to choose plants whose size is easy to control, so they don’t grow too tall. This is to prevent the shoots from getting too close to the grow lights and suffering damage. Opting for compact plants, such as indica varieties, facilitates the control of the space and the maintenance of an optimal environment.

Another relevant consideration is smell. In an enclosed space, plants that give off a strong aroma can attract unwanted attention from neighbours or strangers. Therefore, selecting varieties with a more subtle scent profile can be beneficial to maintain discretion.

Outdoor seeds

For outdoor growing, you must consider the climate and environmental conditions of your region when you choose your strain. Plants that thrive out in the open are usually more robust and resistant to weather, pests, and diseases.

In humid areas with short summers, it is best to opt for fast flowering varieties. These strains help minimise the chances of fungi appearing when the autumn rains begin, since their flowering cycle is completed before the arrival of the more humid climate.

If you live in an area where good weather only lasts a few months, autoflowering marijuana plants are your best bet. These strains don’t depend on the photoperiod and have a very short life cycle, meaning that they are perfect for regions where the outdoor growing season is short. Autos let you make the most of the limited amount of good weather that the summer offers, ensuring a fast and efficient harvest.

By contrast, if your grow is in a region with a Mediterranean or warm climate, you have the advantage of being able to enjoy ideal conditions for almost any variety. This climate leads to optimal growth, offering the flexibility to choose from a wide range of genetics without worrying about severe atmospheric constraints. This includes both short and long flowering varieties, as well as autoflowerings, whilst always ensuring vigorous development and an abundant yield.

Considering resistance to external factors is also crucial. Cannabis strains that have been bred to withstand varied climates, from the driest and warmest to the wettest and coolest, will guarantee successful outdoor cultivation. Plants that are resistant to mould and common pests are especially valuable to minimise losses and ensure a healthy harvest.

In short, Seedstockers offers a wide range of varieties adapted to different needs and preferences, ensuring that you find the perfect strain for your specific circumstances.

How long does it take to grow cannabis seeds?

The time it takes a marijuana plant to develop from germination to harvest varies depending on the type of seed you choose. The estimated time for each phase of growth is as follows:

Feminised seeds

Germination (3-10 days): During this time, the seed opens, and a small main root begins to grow.

Seedling phase (2-3 weeks): After germination, the plant develops its first true leaves and begins to establish its basic structure.

Vegetative phase (4-8 weeks): The plant focuses on the growth of leaves and stems. Feminised plants can stay in this phase for longer if they’re provided with 18 hours of light and 6 hours of darkness to help maximise their size before the flowering phase.

Flowering phase (6-12 weeks): It starts when the plants are exposed to a cycle of 12 hours of light followed by 12 hours of darkness. Depending on the specific strain, this phase lasts between 6 and 12 weeks. Indicas ripen earlier as an evolutionary response to adverse conditions, whereas sativas can finish flowering several weeks later, since they come from regions with more favourable climates.

Autoflowering seeds

Germination (3-7 days): Autoflowering seeds tend to germinate a little faster than feminised seeds.

Seedling phase (1-2 weeks): The seedling phase is also shorter for autos.

Vegetative phase (2-4 weeks): Autoflowers have a short vegetative phase. These plants start flowering automatically, without the need for a change in the light cycle.

Flowering phase (5-8 weeks): The flowering phase is quite fast for autoflowerings. All in all, these plants can be ready for harvest in about 8 to 12 weeks from germination.

Fast flowering seeds

The germination, seedling, and vegetative phase of these strains are similar in time to those of feminised seeds.

Flowering phase (6-7 weeks): The main advantage of fast flowering seeds is their short flowering phase, which only lasts between 6 and 7 weeks. This lets you get a full harvest about 2 weeks earlier than you would with a typical photo-dependent seed.

To sum up, feminised seeds have a longer growth cycle, but allow for greater control over the size and shape of the plants. In contrast, autoflowering and fast flowering seeds offer a faster harvest, and are ideal for growers looking for quick crop rotation or for those who have limited space. Choosing the right type of seed depends on your specific needs and on the time that you can devote to your grow.

How long are cannabis seeds viable?

Cannabis seeds like Seedstockers’ can be kept and remain viable for several years if stored properly. Under the right storage conditions, marijuana seeds can be used for at least 2 to 3 years. However, there are documented cases of seeds germinating successfully even after 5 to 10 years of storage. Viability decreases over time, so we recommend using the seeds as soon as possible to ensure a higher germination rate.

How to keep your cannabis seeds

To maximise the longevity of your cannabis seeds, it is crucial to store them in optimal conditions. The seeds should be kept in a cool, dry, and dark environment. The ideal temperature for storing seeds is between 4 and 8 degrees Celsius (approximately the temperature of a refrigerator). Humidity should also be low, preferably around 20-30%, to prevent premature germination or the appearance of mould.

Using airtight containers, such as glass jars with silicone seals or plastic bags with an airtight seal, helps protect seeds from moisture and air. Putting a desiccant inside (such as a silica gel pack), can also help keep moisture levels low.

Exposure to light can also damage the seeds and reduce their viability. Store them in a dark place, such as a cupboard or an opaque box. If you use glass jars, make sure they are amber or green so the light can’t pass through them.

Avoid places with temperature fluctuations, such as kitchens or basements without climate control. This is why it is recommended to keep the seeds in a fridge, but preferably in one that is not commonly used, because keeping the door closed for most of the time helps avoid these fluctuations of light, humidity, and temperature.

Before you store your seeds, make sure they’re dry and clean. Residual moisture or dirt can encourage the growth of mould and bacteria. Handle the seeds with clean hands and use sterilised tools if necessary.

Storing marijuana seeds properly can extend their shelf life and ensure a high germination rate when you eventually decide to plant them. With good storage practices, Seedstockers’ cannabis seeds will be ready to lead you to a successful harvest whenever you need them.
