marijuana seed identification guide

In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.

Cannabis seeds vs. clones

Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.

Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.

Remember, once a seed germinates, the real work begins. Sexing, selecting, vegetative growth, flowering, and the eventual harvest all lie ahead.

The simplest way for growers to ensure they have high-quality seeds is by sourcing them from a reputable seed bank. These companies specialize in breeding a variety of marijuana strains and producing seeds that, with the right care, grow into viable, high-yielding plants. Growers can choose a variety that meets their requirements for potency and desired effects and be sure they are getting seeds that produce the plant they want.

Preflowers are the earliest sign of a marijuana plant’s gender. Between four and six weeks, nodes will develop at the joint where a plant’s stem meets the stalk. Female plants develop white hairs at the internodal joints while male plants develop rounded internodal sacs that fill with pollen.

Poor quality seeds have weak shells that are damaged easily. These seeds will have cracks or splits on them that expose the inside. The best seeds have a smooth exterior with few anomalies.

Source Them Well

There are several visual indicators that can give a person an idea about the quality of a marijuana seed. Some details are easy to spot while others take a higher level of scrutiny.

Many growers who have numerous marijuana seeds need to store them long term if they want to germinate them in the future. However, seeds need to be kept in specific conditions to remain viable. They should be stored in a cool, dark, and dry room, much like the environment in which growers dry their harvested marijuana.

The largest seeds are the best ones to grow. It is easier to pick the largest ones if there are several to compare side by side. Growers should look for the most symmetrical seed that is round or shaped slightly like a teardrop. Underdeveloped seeds are small and have an asymmetrical shape.

Good quality marijuana seeds have a waxy coating around the shell. This is easy to see if the seed is held up to the light because the shell will have a slight sheen.

Research is carried out all the time to determine if a plant’s environment has anything to do with the sex it will turn out to be. And while there’s research stating that it does not, there’s just as much research stating that certain species do have their sex determined by the environment. This same research also states that using certain chemical treatments can also reverse the sex of a plant.

While it would be much easier for growers to be able to sex their cannabis seeds, the simple fact is that there’s no way to do it. However, sexing plants early on during their growth period is not only essential, it’s completely possible. Growers can even do it before their plants enter the flowering stage if needed. Then male plants can be removed and growers can enjoy a nice, full crop.

So where do all the myths from sexing cannabis seeds come from?

Common myths on identifying the sex of a cannabis seed

This has been a question that has become a very hot topic online these days. After a quick search, growers can find multiple charts and explanations on how to sex cannabis seeds.

Typically, marijuana plants cannot be sexed until they have already begun to grow. Cannabis seeds will look somewhat identical and plants in the vegetative stage will also look identical,. As the plants move into their flowering stage, they will start to show very clear signs as to what sex they are. While it would be much more convenient for growers to be able to determine sex before this point. The sad truth is that it’s just not possible.

Unfortunately, there’s not much truth to any of these interpretations. It’s simply impossible to tell just by looking at them what the sex of any cannabis seed is. If it was that easy, feminized marijuana seeds would not be as popular as they are. People could simply buy regular seeds and look at them themselves.
