Germination is the process of beginning vegetative growth of the new cannabis plant. Sometimes referred to colloquially as “popping,” this process starts when the seed is exposed to water and light . The seed abandons its state of dormancy, or quiescence, and resumes essential metabolic processes that feed on energy stores to delicately rupture open the shell and grow its first root. This root will elongate until it has taken hold of the medium, after which it will pull two small embryonic leaves (cotyledons) from the seed shell. Cotyledons are in the seed prior to germination, and are not considered “true” leaves. The cotyledons will grow until they are about one centimeter long, and once the stem below this is around five centimeters tall, another set up true leaves will grow out of the top and the stem between the true leaves and cotyledons will continue to elongate.
Today’s common-market cannabis does not contain seeds; the cultivation practices that have made this widespread are rooted in fundamental biological concepts. Cannabis is a dioecious plant, meaning it has separate male and female organisms, just like humans. If a female plant matures in the presence of a male plant, pollen from the male will fertilize the female, and its bracts will contain seeds at the end of the flowering cycle. Seedless cannabis is commonplace even in the product originating from mass-produced outdoor cultivation, but not too long ago, this was not the case.
Buying marijuana seeds is in a bit of a legal gray area. Technically, marijuana seeds are still a cannabis product, so if you live in a place where weed is illegal then seeds are also illegal. However, some people who live in places where weed is not yet legal purchase marijuana seeds from marijuana seed banks as a “souvenir” purchase. Either way, if you want to buy marijuana seeds and cannabis is illegal where you live, then you face some degree of risk. On the other hand, if you live in a weed-legal state, especially one where home growing is allowed, then you should be able to purchase marijuana seeds legally.

Marijuana seeds can be feminized by two different methods : chemical ethylene inhibition, and rodelization. In the first method, a chemical agent (colloidal silver, gibberellic acid, etc.) is applied to the plant to inhibit its production of ethylene, a plant hormone that induces female flower production. Rodelization is a less-used technique that involves exploiting a natural self-defense mechanism of the plant. An unpollinated female cannabis plant with fully mature flowers may, in some cases, grow pollen sacs to fertilize itself to ensure its propagation. In both cases, pollen is collected and used to fertilize other female plants. Given the absence of Y chromosomes, seeds that result from the mature buds are female.
Cannabis seeds are about the size of a peppercorn, ovular in form, and pointed on each end with a ridge that transverses longitudinally on only one side from tip to tip. It is this ridge that opens up during germination. The other side opposite to the ridge is rounded. The body of the seed is brown, but underdeveloped and unfertilized seeds can have an off-white color and are typically smaller in size.
Cannabis seed production begins with the pollen grain of a male plant. From this grain, a pollen tube grows, producing male generative cells that disperse in the form of pollen. The migration of pollen into a female plant ovule triggers pistils to fall off and seed production to begin. The bracts, which contain the ovule, will then fill with seeds.
Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.
Within a week or so you should see a seedling begin to grow from the soil.
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.
Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
