Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.
But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.
What are autoflowering cannabis seeds?
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
A lot of classic weed strains that have been around for a while come in feminized form. Some popular fem seeds are:

How to maximize yields in autoflowering plants?
It’s recommended that you start autoflowers in their final containers because they don’t have a lot of spare time to recover when they are transplanted. Transplant shock can seriously stunt the plant and the loss of even a day or two in the vegetative period can affect yields greatly.
Growers produce good yields with 24 hours, but the quality isn’t as good as plants grown in an 18/6 cycle. The light setup also plays an important role here. Although autos grow well under different types of lighting, they prefer HPS or LEDs over CFL and fluorescent lights.
For instance, if your nutrient chart recommends 5ml/liter, start with 2.5ml or 1.25 ml (1/2 or 1/4 strength) and watch how the plant responds. Some autoflowers, like the Tangie ‘Matic or Gorilla Glue, for example, are voracious feeders and require a stronger dose, but make sure you start with big doses only after experimenting with half-strength nutes at first.
As a grower, your job is to ensure that all the buds receive equal light, and that’s where LST helps a great deal. Most growers begin LST after the plants are “Topped”. Topping is another technique that involves cutting off the tip of the main stem, forcing the plant to grow more colas rather than one. Beginners can even “FIM” their plants, which is another method where you cut off only a part of the tip instead of cutting it entirely.
