You can get cannabis seeds a variety of ways. If you’re lucky you’ve got some good weed with seeds already. All you have to do is clean the marijuana and extract the seeds. That’s pretty simple, except that most weed these days comes without seeds. In fact, it’s been that way so long that it’s not even called “sin semilla”, which was what we called it in the old days before growing only females was common .
You can always buy seeds. In some jurisdictions it’s legal to sell them openly. You can also buy them from magazines or over the internet. The advantage to doing it this way is that you have a wider variety of choice. However, it may be illegal, so check your local laws.
However you do it, you end up with some marijuana seeds.
Different strains of weed produce different strains of seeds. Some are fat, round balls. Others are little. Some are dark. They can be light colored. They can come spotted and dotted. They can have irregular patches of light and dark.
What you need are healthy seeds. The shells should be hard.
If they are soft and green they’re too young.
