Feminized seeds

Feminized cannabis seeds are seeds specially bred to eliminate male chromosomes. In short: with feminized seeds you grow a female plant. Exactly what most growers want and very understandable when knowing that only the female cannabis plant grows smokable buds. In addition and compared to male plants, female plants develop significantly more active substances such as THC and CBD.

The strain will start to flower when receiving less sunlight. This is towards the end of the summer and the transition into autumn. Indoor growers will have to mimic autumn by (gradually) adjusting their light scheme to a 12/12 light scheme.

Although adjusting the light scheme isn’t difficult, it does require some knowledge.

Benefits of feminized seeds

  • Feminized seeds develop female plants and and grow smokable weed
  • Feminized seeds are almost 100% free of hermaphrodites
  • Female plants grown with feminized seeds develop bigger yields compared to autoflowers
  • Plants from feminized seeds produce fewer leaves compared to autoflowers
  • In contrast to autoflowers, female plants grown with feminized seeds are easier to prune

Autoflower seeds

In addition to feminized seeds, a lot of newcomers opt for autoflower seeds. Autoflower seeds have a lot of the same characteristics as feminized seeds. Yet, there are important differences to be recognized.

Where feminized seeds begin to flower as soon as they receive less sunlight (or artificial light) an autoflower will start to flower based on age. For this, the grower doesn’t have to adjust the lighting schedule or wait for the arrival of autumn. Growing an autoflower is therefore much easier than a female plant from feminized seeds.

Benefits of feminized autoflower seeds

  • Autoflowers bloom automatically 
  • Like feminized seeds, autoflower seeds develop female plants and develop consumable cannabis.
  • The cycle from seed to harvest is short which make outdoor growers able to harvest 2-4 times a year when growing outdoors
  • Because autoflower species are crossed with the ruderalis plant the plant becomes less tall and requires less maintenance.
  • Compared to female plants grown with feminized seeds, autoflowers are more resistant to temperature fluctuations, pests and mold.

What is better: feminized or autoflower?

The answer to this question depends on your requirements. Moderate to experienced growers are more likely to opt for feminized seeds. This has several reasons. Yields are generally better and of higher quality. In addition, plants derived from feminized seeds allow various breeding and training methods such as scrog and topping so with feminized seeds the grower is more flexible. Beginners who grow for the first time and growers who are looking for a quick result rather opt for autoflower seeds.
