If you live in a state or country where cannabis is legal, and where individuals are allowed to grow their own weed at home, then you should be able to buy marijuana seeds at most legal dispensaries. This might not be the case if you’re in a location that does not yet allow home growing. The best thing to do is simply check your local laws and ask your local budtender.

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.

If you’re trying to grow just a handful of plants for your own private consumption, then you can get away with purchasing one or two packs at a time. Since most commercially sold marijuana seeds come in packages of 10 or so seeds, 10 to 20 seeds should be enough to ensure a good harvest even if a few seeds fail. This is a baseline for a small, private crop andany larger operations should scale up accordingly.

How much do marijuana seeds cost?

Plants grown from seed develop stronger root structures.

The body of a marijuana seed is spotted or striped, most commonly with light brown specks, but some varieties of cannabis can have red or yellow markings. Plant embryos are contained within seeds and house all of the cells that will eventually differentiate into leaves, roots, and stems. Embryos, found within the reproductive organs, are protected by an outer envelope called the pericarp. Crucial components of the plant embryo are the cotyledons, the first leaves to appear from the seed, and the radicle, which develops into the primary root. Once the seed germinates and begins its growth into a mature plant, special structures called root caps protect the growing tips of the plant.

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.
