Most seeds that you will buy are regular seeds as described above, but here are a couple more types.
Once you see the taproot, it’s time to transfer your germinated seed into its growing medium, such as soil.
Pros and cons of using cannabis seeds
If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.
If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.
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.
How Light Schedules Affect Marijuana Life Stages
How to identify female plants if starting out with regular bagseed?
Tactic 2: Taking a clone and flowering it
The clones should start revealing their gender in a week or two. Males will start developing balls and females will start developing white hairs. Click on the pictures below to see some examples of male and female plants.
(Some marijuana plants can also be hermaphrodites, which means they display both male and female parts on the same plant)
“Auto-flowering” marijuana strains pretty much ignore how much light they get each day. Generally you don’t run into these unless you buy them particularly from a cannabis seed bank.
That means you use an electric timer to automatically shine your grow lights for 12 hours a day, with 12 hours of uninterrupted TOTAL darkness during the plant’s “night period.”
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.
Healthy cannabis seeds are sufficiently matured and therefore have a different appearance than unripened cannabis seeds. For example, viable cannabis seeds meet a number of criteria. Think of the size and shape, hardness of the outside and color.

Shape and size of a cannabis seed
To test the viability of a seed you can place the seed in a glass with distilled water. Seeds that sink within 2 hours have sufficient mass. These seeds generally have a better chance of sprouting than seeds that still float.
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.
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.
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.
