what the difference between feminized and regular cannabis seeds

To know the breeding quality of a male cannabis plant there is only one way, to check the level of its offspring. On the other hand, when you cross 2 mother plants that you have already used to smoke you already know their qualities both in the crop and in the final product, so when you make feminized seeds it is easier to guess the result of the crossing.

With feminized varieties you can make better use of the growing space, as well as saving on substrate and products such as fertilisers, insecticides, etc. You also avoid the problem that can happen if at a given moment you forget to remove a male, or you don’t notice.

It must be clear that the most important thing in the quality of cannabis seeds is their genetics, and this is indifferent if it comes from regular or feminized plants. The choice of breeding parents is the key factor when producing seeds, not just measuring quality by the features we can measure.

🔥 Advantages of regular seeds

The only difference is that from a feminized seed only female specimens should come out, while from a regular seed both female and male or even intersex or hermaphrodite can come out.

Hermaphrodite feminized seeds can also be found, but this is due to a bad choice of parents in the breeding of the variety, therefore, can we say that feminized seeds are good?

The great majority of feminized genetics on the market come from elite clones that have been extensively tested as smoking weed. This is a great advantage, as it is easier to guess the features your offspring may inherit.

However, in their genome they do have a big difference, and that is that feminized seeds only contain female chromosomes (XX). This is so because to create 100% female seeds it is necessary to pollinate a female with another female, that is, (XX) x (XX).

With such a strong (commercial) focus on feminized seeds, it’s easy to forget that regular seeds are vital for the creation and maintaining of a diverse cannabis gene pool. It’s incredibly important that seed banks and breeders take their responsibility and keep offering regular seeds to the cannabis community.

You can begin a small scale breeding project that is relatively straightforward, as the aim is not commercial financial value but to make your own strain. After a long time of breeding with selected clones and male plants, you can possess some of the most breathtaking strains around.


With regular cannabis seeds you can find a genetically untouched phenotype that is totally different and the keeper in your grow room.

Some of the best strains from the old school never made the cut in the feminized market, so over time have been forgotten. There are some old school pre 1990 gems available and simply not available in feminized form. It pays well to do your research about strains and breeders before making your next purchase.

Feminized cannabis seeds are incredibly popular by the home grower, but we should not forget about regular seeds!

For a long time, outside of strain distinctions, cannabis seeds were genetically the same across the board. Relatively recently, though, feminized seeds have become increasingly popular with growers, and are often preferred over regular ones. What are the differences between regular and feminized cannabis seeds? How do they grow? Let’s find out.

If you want to distinguish between the sexes, you’ll have to wait until they’ve started to grow a good deal. Before anything, if your plants are male, you’ll notice their pre-flowers are small, green, and oval-shaped. You can also wait longer to look for the formation of pollen sacs, which are a much more obvious sign, but by then you would’ve used up nutrients and time that you didn’t have to.

Understanding the Sex of Cannabis Plants

With male plants out of the way early, though, your growing process can go on uninterrupted, and you can spend all of your water and nutrients on making sure the females achieve the ideal size and yields.

Focusing on the plants that produce viable buds (i.e. the female plants), you can be sure you’ll get an ideal yield out of them if you treat them right. However, as we mentioned before, on average, only half of the seeds you get in a pack will produce female plants. Ergo, per 10 seeds, you likely won’t get nearly as high of a collective yield as you would with a pack of 10 feminized seeds. In turn, if you let the male plants pollinate the females, you’ll get far lower yields across the board than you would otherwise.

Really, as we’ve discussed, it depends entirely on what your goals are as a grower. Are you trying to breed new strains and grow the seeds/clones from your plants? If so, regular seeds are the way to go, as they have far more stable genetics, and regular seed packs will produce male plants for the breeding process.
