The frustration and guesswork in successful cannabis growing is dramatically reduced by feminized cannabis seeds. There’s no worry about timing and separating male plants before you end up with a seedy mess; instead, you’re guaranteed to grow only female cannabis plants covered in heavy, sticky buds.
Obviously, since 100% of the nutrients, light, and effort that you invest into your plants results in a harvestable product, feminized seeds result in a much better return on investment than regular cannabis seeds, which take all of your work but only produce half the results.
To produce feminized seeds, growers essentially breed female-dominant plants together to eliminate the male chromosomes. Female plants produce male flowers under stress, such as when the light cycle is interrupted, and the flowers from those genetically female plants may be used to fertilize other female plants. Repeating this process eliminates male genetics over time, producing feminized seeds.
Early versions of feminized seeds were less reliable, sometimes producing plants that were prone to hermaphroditism. However, that problem has been corrected by subjecting the more feminine plants to stress over time to actually feminize seeds genetically.
Modern feminized cannabis seeds from a reputable merchant will produce only female plants. There is no need to cull males or sex plants at all, and you can expect dense canopies and heavy nugs from these grows.
Feminized seeds produce photoperiod strains that flower according to how available light fluctuates. Indoor growers retain total control over their plants and can take them straight from seed to flower or keep them in the veg stage for as long as desired. Outside, the plants flower based on seasonal rhythms, but it’s much easier to control the process inside.
In this post, we describe some of our favorite varieties of feminized seeds. They are awesome as solo grows or as part of a cash crop. We’ve aimed to present options from all over the indica-sativa spectrum.
These high-end strains represent the best feminized seeds on the market right now. They each deliver intense effects, delicious aroma and flavor, and high yields to keep you going through the season. And, again, unlike regular seeds, there’s no need to waste time culling male plants.
