Greetings @mysterious_stranger,
There are a bunch of good suggestions and referenced materials above that should help you understand the terminology and techniques of cannabis breeding, but I suspect you might benefit from a perspective on the practical side.
I’m over two years into a breeding project now and I’d like to share a few insights.
-
Making seeds is easy and fun, cannabis breeding isn’t!
-
Breeding is a serious activity and requires serious planning in advance. If you don’t have a very clear goal in mind you can expect frustration and likely failure.
-
Breeding is a long term commitment to a series of sequential grows that produce the intermediate results towards your goal. Many of them aren’t very interesting by themselves, but must be performed for the long term success of your project. In most cases the growing is continuous all year long uninterrupted. That’s hard on life and family.
-
Breeding is lonely work, with results measured in months and years and the outcome always uncertain. If you don’t have a clear goal from the onset it can be hard to stay motivated.
-
Overgrow has dozens of very talented breeders working overtime to create new wonders and classic revivals for our use and enjoyment. If you are successful in your breeding project, you will face an audience that has a plethora of offerings on the table.
If I read your OP correctly, you really just want the excitement of making some seeds. If that is so, don’t sweat the details, grow some males and females, let them do their dance, enjoy the sublime mysteries of cannabis biology and have a happy life. Leave breeding to us lonely compulsive obsessives haunted by visions of delivering unto the World our really, truly, super-special dream weed!
Respectfully,
-Grouchy
