For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.
Cannabis seeds vs. clones
You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.

The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.
Preparing to germinate cannabis seeds
So, you’ve decided to grow your own cannabis plants. You purchased a pack of seeds, assembled cultivation materials, cleared a space in your garden, and are ready to grow your first cannabis crop . With everything in hand, it’s time to begin the very first step of cannabis cultivation : germinating seeds.
What is germination?
Place the soil in a small pot and use your finger or a pencil to push a small hole in the dirt, a bit more than half an inch deep. Insert the seed into the hole and bury it with soil. From this point on, don’t touch your seed. The young plant is fragile and knows how to position itself in the soil bed.
With all this being said, plants are natural, living things and like all living things, they’re complicated. You can do everything perfectly, meet every environmental requirement and some seeds just won’t germinate. It’s a natural part of growing and certainly not something to be disheartened by if you’re new to growing.
Success in seed germination is actually quite straightforward as there are only three factors that really matter: water, temperature, and oxygen.
How Long to Germinate Cannabis Seeds
It’s the most important time of your growing cycle, often overlooked in favor of other stages like vegetation and flowers, but germination is where the magic really happens.
All this being said, if these simple conditions are met, most seeds will germinate. Depending on your germination method, you’ll know if this has been successful as you’ll be able to see a small, white root sprout from the bottom of the seed.
What Is Germination?
Let’s get the jargon out the way first. Simply put, germination is the development or growth of a plant from a seed or spore, usually after a period of dormancy (like if the seeds have been sitting in a jar to store them). It’s also known less scientifically as sprouting. During this process, your seed will crack open and sprout a single root, known as a tap root, before beginning the growth stages above the soil.
