However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.
If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.
Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.
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.
As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).
Although it isn’t always visible with the blind eye, on a quality cannabis seed you can see a pattern of “tiger stripes” or dark spots.
A well ripened cannabis seed had sufficient time for hardening its shell. Healthy cannabis seeds are therefore provided with a hard smooth skin without cracks. You can test the hardness of the shell by taking the seed between your fingers and applying gentle pressure. Immature seeds will easily crack or crumble while qualitative cannabis seeds won’t damage.
Some people believe you can see the gender of the strain based on the appearance of the seeds. Well, we can tell you that ain’t possible. Both female and male seeds look exactly the same.
Fertile cannabis seeds are black, dark brown, red-brown or gray with a shiny glow as if there is a bit of wax on the peel. Cannabis seeds with a different color such as white, yellow or light green will probably also germinate, but indicate lesser quality. Such seeds have been harvested too early and haven’t had enough time to ripen.
Note: the moisture from your fingers can damage the seed. Please use linen gloves to prevent this.
Note: this test isn’t 100% accurate and only provides an indication of the viability. In addition, the water will activate the germination process. Therefore, only carry out this test if you want to germinate the seed immediately. After performing the float test, you can’t longer store the seed.
Cannabis seeds have a unique shape. They are oval, have the shape of a drop and are small in size. On average, a cannabis seed is about 2 to 5 mm long and 2 to 3 mm thick. If you want to know what you can expect in advance, then we can advise you to take a look at the seeds of a tomato.
A mature, high-quality marijuana seed has a hard shell that can withstand the pressure of being squeezed between two fingers. Poor quality seeds will disintegrate when squeezed. If this happens, the seed was weak or dead and would not have grown a viable plant if it germinated at all.
The float test is a more scientific approach to determining the quality of a seed. The test involves filling a drinking glass with spring or distilled water and placing the seeds inside of it. Allow the seeds to soak for one to two hours before determining quality.
After the time has passed, seeds that float can be considered poor quality and discarded. Seeds that have sunk to the bottom of the glass are healthy, high-quality seeds. Once the test is complete, the seeds need to be germinated right away. Their shells will be soft from soaking in the water and will not survive storage.
When growing marijuana, it is important to identify male plants as early as possible. Just one male plant can pollinate an entire field, so it is critical that male plants are removed before they develop pollen sacs. There are certain signs that a young marijuana plant is male, including the following:
Those who live in a state where marijuana is legal for medical or recreational use can sometimes find seeds at their local dispensary. However, online marijuana seed banks have significantly more strains available. Even individuals who live in some states where marijuana has not been made legal to use can purchase seeds online. Several states consider dormant seeds to be souvenirs, so it is legal to purchase and own the seeds as long as they don’t become high-THC plants.
