To those who say this type of reproduction just doesn’t seem right, the evolutionary strategy of plants using only female and hermaphrodite plants to breed is actually pretty common and is known as gynodioecy. One example of a plant that only reproduces this way is a flower found in Canada and the US called Lobelia siphilitica, also known as the Great Lobelia. Obviously this reproduction method isn’t exactly the same as artificial feminization since the pollen production is caused naturally instead of induced chemically, but examples of gynodioecy show that a female flower-based breeding population can exist in the wild even when no plants are purely male.
Make sure that you’re touching all the female pistils/hairs with your pollen. Here’s a little video showing you exactly what this looks like!
Although I have a few anecdotes from growers who have used only feminized seeds for a few generations, it would be much better to share information from someone who has conducted plenty of testing over several generations. We’d love to hear from you if you have bred more than a few generations using only feminized seeds and want to share your experience!
How can I identify plant gender before the plant actually starts flowering? (Besides using feminized seeds)
This is what it looks like when the seed is exposed
6 Weeks to Harvest Seeds – After about 6 weeks from pollination, the calyxes on the buds of your female plant will be swollen and fat. You know it’s time to harvest your seeds when they start bursting out. At this point, it’s time to congratulate yourself because you’ve got feminized seeds!
Note: If you’re feminizing an auto-flowering plant, start spraying daily when the plant is about 20 days old from seed. This is when most auto-flowering cannabis strains start making flowers.
This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:
Additionally, every long-time grower will tell you that clones degrade over time.
What are autoflowering cannabis seeds?
Within a week or so you should see a seedling begin to grow from the soil.
This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.
Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.
