Within a week or so you should see a seedling begin to grow from the soil.

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.

Step 3

If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.

If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.

But if the seed you found looks decent, you might as well germinate it and see what sprouts.

Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.

Noting when and how a weed emerges and grows can aid in identification. Summer annuals are mostly frost-tender, usually emerge between the spring frost-free date and late summer, and die at the first fall frost. Winter annuals emerge any time between the end of summer and early the following spring, flower and set seed in spring or early summer, and usually dry up with the onset of hot weather. Thus a weed that is still thriving after a fall frost is almost certainly not a summer annual such as pigweed, purslane, or galinsoga, and a weed that is succulent and vegetative in July is probably not a winter annual like henbit or yellow rocket.

Any of these methods is only as good as the weed manual, key, or database used, the quality of the specimens available, and the observation skills of the user. If the weed in question is not included in the key or guide being used, you can waste a lot of time searching for it in vain! It is important to choose a manual or database that is written for your region and includes all of the region's major agricultural weeds. If a particular weed cannot be found in the reference you are using, it could mean any of the following:

Identifying Weeds at an Early Age

Some weed manuals include good photographs and descriptions of seedling characteristics that allow identification of the weed’s plant family or genus, if not species. Seedling characteristics include:

Figure 2. The small weeds in this photo are true seedlings, having germinated over the past two weeks. The larger weeds with somewhat arrow-shaped leaves are shoots of hedge bindweed that have emerged from rhizome or rhizome fragments within the top foot or so of soil.
