Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.
One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.
As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.
These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.
Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.
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.
Once you see the taproot, it’s time to transfer your germinated seed into its growing medium, such as soil.
8 – Cannabis seeds have been found on a wide range of archaeological sites, including in Viking ship burials and within the tombs of Chinese mummies. Often they appear in contexts where hemp was not widely used for rope or textiles, suggesting that it was the THC which appealed to the people who left the seeds there.
3 – Genetics from the Ruderalis sub-species are often included in popular strains because this is the only one of the three main types which flowers based on age rather than the length of daylight exposure – thus creating autoflowering seeds. This, along with the fact that Ruderalis is a very hardy herb, means that it is prized for creating hybrids even though its natural THC content is extremely low.
7 – Cannabis is a pretty hardy weed, so it isn’t actually that difficult to get the seeds to turn into seedlings: they will grow whenever and wherever they get the chance. To germinate they need moisture, warmth and a little bit of time. Most seeds will start to produce roots within 72 hours of being tucked up somewhere damp and humid, and although they are very delicate at this stage, they will grow quickly if they get sufficient sunlight and nutrition.
9 – In southern Poland there is a traditional soup called siemieniotka which is made from cannabis seeds. It is traditionally enjoyed at Wigilia, the Christmas Eve supper that forms the focal point of the Christmas festivities.
1 – Cannabis seeds contain the “genotype” of the plant, the genetic code which provides the instructions for building the finished “phenotype”. This DNA is often a hybrid of genetics from the three recognized cannabis sub-species: Sativa, Indica and Ruderalis.
5 – The majority of cannabis seeds on the market are hybrids from a dizzying lineage of cross-breeds. Seeds of landrace strains are different: they’re from plants which occur naturally in the wild, and their genetics have been shaped by natural – rather than artificial – selection.
6 – Hemp oil, which is produced by pressing cannabis seeds, is used in the manufacture of a wide range of beauty products and plastics, but it is also prized as a food supplement because of its high levels of essential fatty acids (EFAs). The seeds themselves contain no THC, so hemp oil is not psychoactive.
Immature cannabis seeds, on the other hand, tend to be green and have a soft outer shell that breaks when any kind of pressure is applied to it.
This is absolutely not true. As we explained earlier, cannabis seeds naturally look different, and no single physical trait of a seed can tell you whether that seed contains the genetics for a male or female plant. The only way to tell a female cannabis plant from a male is by looking at its flowers when it begins to sex. Don’t be fooled into throwing out perfectly healthy seeds just because a popular internet chart told you so.
Growing Seeds From A Bag (Bagseed)
A quick web search will bring up all kinds of myths about how to tell female cannabis seeds from males. One of the most popular ones comes from a chart showing 5 different seeds that claims that the female seeds have “a perfectly round volcano-like depression at the bottom (from where the seed was attached to the plant).”
Keep in mind that the simple process of packaging and storing cannabis seeds can also affect their appearance. Abrupt changes in humidity, temperature, or light exposure can make some seeds appear darker or lighter than others, but ultimately have no effect on their quality.
However, slight patience is required when conducting the float test, as results are not immediately apparent. You’ll have to wait for approximately 1–2 hours before confirming the results. Some good-quality seeds will need adequate time to absorb enough water for them to sink. Use this time to go water the garden and get some much needed pruning done. Upon your return, any seeds that remain on the surface are most likely not viable and won’t be worth further time and effort.
