A seed is the reproductive body of a plant that can grow into another plant. It consists of an embryo, stored food and a protective coat.

In plants, seeds are important for reproduction and dispersal. They are also used to produce oil, fiber, and food products. Some seeds have medicinal properties.

Germination

Germination is the process by which a seed starts to grow into a plant. All seeds need the right temperature, water, oxygen and sometimes light or darkness to germinate.

Most seeds have a protective layer that protects them from the elements and insects, but it can also inhibit germination. The seed’s coating can clog up the nutrient flow to the embryo.

To break this barrier, the seed needs to swell and split open. This happens when the seed is soaked in water, which softens the coating and allows the nutrients to get through.

This process can take as little as one day, but can be longer depending on the species and its unique germination conditions. Once the root has broken through the seed coat, it goes down into the soil looking for water and nutrients. Next, the shoot grows up in search of sunlight. The whole germination process takes one to two weeks to complete.

Soil Conditions

Seeds need water and oxygen, but they also require optimal soil conditions. These can include proper temperature, light and adequate moisture to germinate properly.

During germination, a seed’s protective coating breaks down and the embryo’s cells start to enlarge. It then takes in water and oxygen through the seed coat.

Soil conditions that promote germination (or emergence) can be determined by soil texture, moisture availability and ground cover. Soils that are sandy or drain well tend to warm up faster than heavy, water-logged soils.

Wet-thermal models use germination trials conducted in the laboratory to determine the rate of seed germination as a function of soil moisture availability and temperature. They have been shown to be highly predictive of germination responses measured by hydrothermal models in field tests (Hardegree et al., 2018).

Temperature

While seed germination is dependent on many factors, including seed vitality, soil moisture and air quality, the soil temperature plays an important role in the speed of germination. Whether you are directly sowing seeds in the garden or starting them indoors, achieving optimal soil temperatures will increase the germination rate and result in more vigorous plants.

Using a soil thermometer, insert it 3 to 4 inches deep into the soil surface and note the temperature. Planting at the optimum temperature for a particular crop will ensure that hearty seedlings will be ready to harvest.

All seeds have an optimum temperature at which they will germinate. Depending on the species, this range is between 55 and 80 degrees Fahrenheit or 21.1 and 27.7 degrees Celsius.

Light

The light that a seed receives can either promote or inhibit its ability to germinate. This is largely down to the wavelengths of light, which are in the red and blue spectrums.

The effect of light on germination is complicated by the fact that different seeds have varying degrees of sensitivity to light. It is sometimes only part of the seed that is light sensitive, like the micropyle on phacelia, or even just one point on the surface of lettuce.

In other cases the whole seed will need to be exposed to light for it to germinate, such as in the case of a tiny flower bulb. In such a case, the seed will have to be covered with a thin sprinkling of vermiculite after sowing and left in diffused light until germination takes place.

Most gardeners use fluorescent shop lights or light-emitting diode (LED) bulbs for seed starting. LEDs are energy-efficient and available in a wide variety of shapes and sizes.

When it comes to growing cannabis, there are many options, including autoflowering and feminized seeds. Each option has its pros and cons, so it’s important to choose the right one for your specific needs.

Regular seed is the most common type of marijuana seeds, and it offers a pure and untampered experience. It’s also a good choice for old-school growers who want to experiment with breeding both male and female strains.

They are cheaper

Regular seeds are a cheaper option than their feminized counterparts. They are also much easier to grow and breed than feminized seeds, which can be a real advantage for beginner growers.

Feminized seed, on the other hand, are designed to produce only female plants. They are a popular choice for commercial growers as they can provide higher yields and better-quality crops.

If you are looking for a good deal on high-quality cannabis seed, Quebec Seed Bank is an excellent choice. They offer a variety of different types of cannabis seeds, including feminized and autoflowering varieties.

In addition, the online seed bank offers discounts and special deals on a variety of strains. Keep an eye out for sales during holidays like 420, Christmas, 4th of July, etc. Alternatively, you can check their website for regular 30-50% discounts on hundreds of strains.

They are easier to grow

Regular seeds are a great choice for growers who are looking to cultivate a variety of cannabis strains. They are less expensive than feminized seeds and allow you to germinate just the number of plants that you need at any given time, without the worry of accidentally producing males.

They are also easier to breed than feminized seeds as they are essentially untouched by any genetic modification. This means that you can create clones that are genetically stable and will produce the same strain with every generation.

Another great advantage of regular seed is that it allows you to combine different strains to create new and exciting hybrids. You can cross an indica-dominant strain with a sativa-dominant cultivar or a hybrid with a strong terpene profile to create something completely unique.

While they are a little more complicated to grow, the results are well worth it. You can create a new strain that’s packed full of cannabinoids and terpenes, or take a classic and turn it into a hybrid that’s better suited for outdoor cultivation.

They are more stable

If you want to make sure your cannabis plants will be genetically stable, a good choice is regular seed. This is because these seeds haven’t undergone any genetic modification, which makes them more stable than their feminized counterparts.

In addition, they tend to be a bit more vigorous than their feminized counterparts, which can work in your favour when you’re growing under stress. They also have a better chance of producing robust offspring.

A final advantage of regular seeds is that they are much cheaper than their feminized counterparts. In fact, they can be half as expensive, meaning you’ll end up with twice as many plants!

If you’re a keen breeder, then you’ll definitely want to stock some regular seed. This is because they can produce a variety of different phenotypes, which can prove to be quite interesting and rewarding for growers who have a knack for experimentation. They’ll also be a great choice for people who enjoy keeping mother plants for taking cuttings/clones (also known as asexual reproduction). This is because they have more stable plant genetics than their feminized counterparts.

They are easier to breed

Regular cannabis seeds are easy to breed, making it easier for growers of all levels to develop their own strains. They also provide superior clones that are suitable for breeding with feminized or autoflowering varieties.

Feminized seed offers more advantages than regular cannabis seeds, and it is ideal for beginners who want to practise growing marijuana plants without worrying about the complexities of breeding. However, these types of seeds are less pure than their regular counterparts.

Despite this, a lot of growers prefer to use feminized seeds in their first crops. This way, they are able to practice growing marijuana plants without having to worry about the complexities of breeding, thus enabling them to become better growers in the long term.

Regular seeds are cannabis seeds that result from a breeding line of genetics expressing an equal proportion of male and female chromosomes. They are commonly used by traditional gardeners and breeders who have not yet fully adapted to the concept of feminized seed technology.

These seeds are a good choice for beginner growers who want to hone their growing skills and get acquainted with the intricacies of marijuana plant breeding. They are also less prone to turning into hermaphrodites (developing both male and female flowers) than feminized seeds.

Breeding

Cannabis breeding is the process of combining two strains together to create new cultivars. It can be used to create strains with specific traits, such as potency, colour, or flavour, but it is also an excellent way to experiment with new terpene profiles.

Breeding regular seeds is an exciting voyage, but it requires a lot of patience and experimentation. Ideally, growers should start by choosing specimens that produce the desired phenotypes and then cross them to produce offspring.

When selecting males for breeding, growers should look for plants that are tall, have large leaves and are well-structured. They should also choose females that are similar in height, shape and leaf pattern to ensure the results of the breeding process are consistent.

Once these plants have been cultivated to maturity, they can be crossed with each other using cloning techniques to produce commercial hybrid seed stocks. The resulting strains are typically strong and resilient, making them suitable for growing outdoors.

Cloning

Despite the obvious benefits of cloning regular seeds, they still have some limitations. For starters, they’re difficult to find if you don’t have access to a network of growers who offer genuinely elite clones that are free from pests and disease.

Genetic issues are typically disappointing, but pests and diseases can have devastating effects on your entire grow room if you don’t take the time to vet your clone source.

The best time to clone is during the vegetative phase of the mother plant, which lasts about two months. This gives the clone a head start, and allows the root system to develop more fully before flowering starts.

After cutting, place the clone into a cup of water to encourage the roots to develop. Once they begin to grow, you can then transplant them into soil or a growing medium. This process takes about three to 14 days, depending on the clone’s roots and the growing conditions.

Seed Saving

Saving seed is an important way to preserve your favorite garden varieties, as well as heirloom seeds. It can be a rewarding hobby for anyone who enjoys gardening and is willing to take the time to save the seeds of their favorite plants.

The easiest vegetables to save for seed are those that are self-pollinating, like tomatoes, peppers, peas, beans and lettuce. These are also the most reliable since there is no need to manage pollination and germination.

Insect-pollinated and biennial crops such as carrots, beets, cabbage, radishes and parsnips are harder to save for seed because they require two growing seasons before they can set seed. They are also more likely to cross-pollinate, so you will have to take additional steps to ensure your saved seed is pure.

Fortunately, other fruits and vegetables that have perfect flowers, like cucumbers, okra, melons, tomato and bell pepper, are good crops for beginner seed savers. You can plant just one variety of each to achieve true-to-type seeds when adequately isolated from other gardens.

Genetic Preservation

Regular seeds stored in the genebank can be a valuable resource to support genetic diversity conservation, plant breeding and restoration of endangered plants. They also serve as an insurance policy against the loss of wild populations in a changing environment.

Long-term storage requires a cool, dark and dry environment with minimal oxygen. Film canisters, medicine bottles (non-translucent) and sealable containers work well for this purpose.

Depending on the species, seed longevity in storage varies from a few years to decades. The amount of time a seed will remain viable depends on the temperature and relative humidity during storage, its composition, and the duration of harvesting and drying.

A seed sample should consist of at least 3000 seeds, irrespective of morphological variation, for genetically homogeneous accessions and 4000 or more for heterogeneous materials. This can be converted from the number of seeds to the thousand seed weight using the approximate weights given in Appendix 2 of Cromarty, Ellis and Roberts (1982). Against the key success criteria proposed by Brown and Marshall [15] seed collections were successful for two focal species (M. balbisiana 81% and M. maclayi 93%), and less for M. acuminata (Figs 2 and 3).
