sexed seeds

Regular sexed Cannabis seeds represent a breeding line that expresses an equal balance of male and female chromosomes. Working from seed using regulars is an excellent way to grow out large selections of either male or female plants. Knowing which plants belong to which sex, how to identify them early on and understanding the life cycle of a Cannabis plant, will give you the advantage when pheno hunting for an upcoming breeding project.

When a Cannabis seedling has been left to grow for up to 5 weeks under 18/6, the plant will begin to exhibit very small preflowers. Typically these preflowers reveal themselves once flowering is induced, however it is possible to see which sex you have when knowing what to look for.

Why Grow Using Regular Seeds?

There are plenty of old school genetics that have stood the test of time, and due to the marketplace during that era, were never feminized. It was from around early 2000 onwards, when the advantages of feminized seeds were becoming commercially popular. Many cultivars that existed during the last 50 years are often preserved in regular seed form, either as a first generation or as a stable IBL. Back crossing or producing a new generation of cultivar should only be done with regular seeds, especially when in-breeding.

For those who have the desire to make your own custom genetic crosses, starting your own breeding project in the comfort of your own home is easily achievable. For this you will need to invest in regular seeds that will allow you to grow either male or female plants. It is a good idea to start with at least 10 seeds to allow for a much wider variation, and greater choice of male to females. Some seedlings may underperform and be discarded early on, however with 10 seedlings, there is a good potential desired ratio. Labeling your pots with numbers and strain names, will make life much easier when sorting through the different plants, especially when taking cuttings before flowering for preservation purposes.

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.

Common myths on identifying the sex of a cannabis seed

This will mostly happen when a plant is stressed by its environment. When this happens, the plant may think it’s going to die and as a result, will change itself into a hermaphrodite plant. By doing so, it will be able to self-pollinate itself and survive.

While environmental factors may not necessarily determine the sex of marijuana plants or cannabis seeds, it is known that certain environments can change the sex of a plant.

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.

Growers know that hermaphrodite plants can be just as harmful to crops as male plants. Therefore, it’s very important that every grower understand how to sex marijuana plants. Particularly if they’re not using feminized marijuana seeds that will give them only females.
