When we grow cannabis from seeds that meet the highest global quality standards, it’s always an interesting and exciting adventure: it allows us to experiment and discover plants with slightly varying characteristics within the same genetic line.
\n\n\n\nIt is a unique process, more entertaining and full of more surprises than growing plants solely from cuttings. This approach gives us the opportunity to marvel at characteristics that can reveal exceptional uniqueness in the individual expression of a cannabis plant.
\n\n\n\nThis is certainly one of the most exciting stages, even for the most skilled and experienced growers. Why? Because there is an artistic aspect to it, combined with the element of rarity: it is possible that the specimen you encounter will exhibit a variety of unique qualities, all embodied in a single individual.
\n\n\n\nFor all these reasons, growers may feel compelled to preserve and maintain all the desirable qualities found in this unique plant. However, the aspects that dazzle us about it can sometimes be misleading: here, then, is a guide to help you make the right choice.
\n\n\n\nSelection criteria vary and are subjective, as they depend primarily on your personal preferences and expectations, or on aspecific professional goal you are seeking to achieve. Here are the eight key points to consider before choosing your future mother plant.
\n\n\n\n\n\n\nSeed vigor is a key factor to consider: it is the very first qualitative indicator of the vitality and overall potential of the genetic material you have.
\n\n\n\nThis vigor may be directly linked to genetics and represent a characteristic unique to the lineage, since most of the hybrids on the market today are actually quite complex polyhybrids (the vast majority of U.S. varieties).
\n\n\n\nIn practical terms, this means that the breeder who developed a new variety sought to obtain one or more specific traits. But since we’re dealing with living beings, we’re always talking about statistics within a population: there are therefore always variations among the different individuals of the same lineage. It is thus very difficult to find an individual that possesses all the ideal characteristics, because perfection does not exist.
\n\n\n\nJust keep in mind that strong germination is generally a good indicator, although this can vary depending on the cannabis strain being grown.
\n\n\n\nAnother important factor is the vigor and speed with which the root system develops. The root system is, in a sense, the plant’s “digestive system”: it enables the plant to develop a strong, robust structure while maintaining an immune system that can withstand any challenge.
\n\n\n\nRapid and vigorous root development also offers another advantage, which is inextricably linked to the first: it determines the plant’s future ability to be propagated via cuttings. It is essential to understand this dual aspect. At this stage, you will already have an idea of your “favorite plant’s” potential for rooting—and thus for propagation via cuttings.
It is important to pay attention both to the vigor displayed during the plant’s growth and to the uniform and robust development of its various parts: the central stem, the nodes (internodal distance), and the secondary branches. Do not hesitate to cull certain problematic phenotypes that exhibit abnormal traits, such as deformities or strange mutations ( plants with an odd structure, leaves with uneven coloring , etc.), even if this type of plant produces a delicious flavor profile during tasting; keep in mind that a well-developed, vigorous vegetative structure with numerous branches will always ensure a better yield.
This is why, at least for professional and commercial use, it is imperative that the selected mother plant possess the most comprehensive characteristics possible. These observations will provide direct insight into the speed of growth during the vegetative phase, how to manage the plant to achieve a specific result, and its flowering capacity (flowering pattern). Ultimately, this has a direct impact on the total duration of the grow cycle as well as on the final yield.

It is important to examine this organ in great detail: the uniform development of the petiole, the intensity of its color, and the sharp definition of the leaf and its veins. Regardless of the variety’s dominance (Sativa, Indica, or Ruderalis), the individual leaf segments should be similar in size and shape, without any wrinkles or deformities. (crocodile-skin appearance, fairly pale color, inconsistent size or shape).
\n\n\n\nThis is a point that should not be overlooked, as it can lead to numerous problems during the plant’s various stages of development, both during growth and flowering . This aspect depends directly on the genetic heritage and combination of one or more strains. It provides reliable information about the level of immune resistance of the individual you are considering preserving for your future projects. Some cannabis varieties are naturally more resistant than others to these harmful phenomena, particularly due to the shape and density of their resin trichomes, as well as their unique aromatic profile.
\n\n\n\nThis is a sensitive topic that often raises questions—and even doubts—among many growers as well as the most experienced breeders.
\n\n\n\nAll professionals in the field know that this phenomenon is difficult to control. Contrary to popular belief, its occurrence—whether mild or pronounced—is not necessarily a sign of poor breeding practices. The reasons are often more deep-rooted: the inheritance of recessive or dominant male genes present in the genetic makeup of one or more bloodlines, which are present in varying proportions when a new variety or hybrid is created.
\n\n\n\nSince most of the high-quality cannabis seeds available today are F1 hybrids, this sometimes results in unpredictable combinations, opening the door to billions of possibilities within a single strain. This is a fascinating aspect, as it allows for the discovery of very different and unique plants within the same genetic line.
\n\n\n\nIt is also important to keep in mind that virtually all of the varieties currently on the market are polyhybrids, which increases the instability and the wide range of possible variations in this phenomenon, making it very difficult to fully control.
\n\n\n\nIn practical terms, these variations can result in individuals in which male flowers appear for either a short or a long period of time. Rigorous intergenerational selection, along with stress tests, makes it possible to assess a variety’s response to various stresses and to minimize this phenomenon of hermaphroditism as much as possible— though , since we are dealing with living organisms, it is not possible to guarantee complete control over it.

In most cases, this undesirable phenomenon is, fortunately, temporary and short-lived. That is why it is generally recommended to remove the male flowers as they appear during the flowering period. In most cases, male flower production stops after 5 to 6 days at most. That’s why, for certain exotic varieties where this phenomenon occurs exceptionally, we sometimes recommend simply removing all male flowers from the affected plant and remaining highly vigilant for about a week, which should allow you to save your harvest overall.
\n\n\n\nOn the other hand, if the problem persists and becomes difficult to manage, it is best to isolate the affected plant and then dispose of it if the situation does not improve. A strain with this trait will continue to exhibit it indefinitely; this is an important point to keep in mind before making your final decision.
\n\n\n\nDuring the flowering phase, carefully monitor the rate of development and bud formation. The buds should ideally have a uniform structure with a good flower-to-leaf ratio; the density of resin trichome production is also a key factor.
\n\n\n\nAnother interesting aspect is identifying the exact moment when the flowering “boom” occurs, so you can adjust the nutrition and optimize both the yield and the overall quality of your flowers. Certain strains have this distinctive trait: they seem to grow more slowly during the first few weeks of both vegetative growth and flowering, and then, quite surprisingly and suddenly, everything accelerates favorably as a whole, ultimately yielding an excellent harvest of top-quality cannabis flowers.

After harvesting and drying comes a crucial moment: the objective analysis of all the qualities of your cannabis flowers—their overall appearance (shape and “bag appeal”), density, flower-to-leaf ratio, aromatic profile, taste, effect, resin content, as well as the overall final yield per plant and the total harvest.
\n\n\n\nIt is at this precise moment that you will be able to make an informed decision about whether it is worth keeping the plant that has caught your attention throughout the growing cycle. It is also the moment when you may experience major disappointments… or, on the contrary, fabulous surprises!
\n\n\n\nIf you observe significant weaknesses in the key areas discussed in this article—such as a plant that has difficulty taking root, slow growth, a fragile structure, one or more deformities, or a marked susceptibility to pests and pathogens—these are all signs that the plant in question is vulnerable.
\n\n\n\nHowever, it is entirely possible that the quality of the aroma, flavor, or effect of that same plant is exceptional, and thus justifies keeping it as a parent plant. A clone with imperfect characteristics can still be retained for one or more specific reasons within a moderately sized cannabis grow operation, but when considering its use for commercial production, its viability will quickly be compromised. As mentioned throughout this article, these are personal and subjective reasons that depend solely on your own selection criteria.
\n\n\n\nSo make your choices based on your priorities: that's the best way to get the most enjoyment out of your favorite hobby!
