At MSC we have worked hard to produce the highest quality feminized seeds on the market with a 99.9% guarantee that they will produce a female plant.

Since the early 90’s when feminized seeds were first introduced the stability and quality of the seeds has come on a long way. Our breeding team now produces over 70 different varieties of feminized cannabis seeds so there is a strain to suit everyone.

Prior to the introduction of feminized marijuana seeds, growers would have to keep a close eye on their grow and pull out any male plants to prevent pollination.

What are feminized seeds

Feminized seeds are cannabis seeds that have had the male chromosome taken out so that they are only able to produce female cannabis plants.

They are made through a process whereby plants are sprayed with colloidal silver. The silver ions in the spray induce feminized pollen by inhibiting the ethylene production which is required to produce female flowers.

Feminized vs regular seeds – What is the difference?

Regular cannabis seeds produce an average ratio of 50:50 male to female plants. This can cause problems for anyone growing cannabis with the sole intention of producing lots of smokable bud.

If you were to grow ten regular seeds, it is likely that you would produce around five male plants and five female plants. Female plants produce flowers or what we call bud, whereas male plants produce pollen that forms in small sacks.

If the intention was to grow female plants you would need to separate the male and female plants, typically culling the male plants before they are given the chance to pollinate the rest of your crop. Once pollinated any bud would then start to produce seeds inside it, effectively ruining the entire crop by making the weed unusable.

Regular seeds on the other hand are great for anyone looking to breed or with the intention to produce their own cannabis strains.

Feminized seeds vs Autoflowering seeds

Autoflowers, also referred to as ruderalis, are strains that are native to regions of Asia, Siberia, Eastern Europe and Russia. Typically ruderalis grows in colder mountainous regions where there is less daylight. Because of this, the plant has adapted to flower regardless of the number of hours in the day, hence why it adopted the name ‘autoflower’.

What is a photoperiod strain? Photoperiods are cannabis strains that have two main phases of their life cycle, the vegetative stage and the flowering stage. Photoperiod strains differ from autoflowers in that they do require a change in their light cycle to trigger the flowering stage to begin. This is why if you are cultivating photoperiods two different light cycles are required, one of 18/6 during the vegetative stage and one of 12/12 during the flowering stage.

Although this may seem confusing most autoflowers are also feminized as well and only produce female plants. However autoflowers are categorised as autoflowers simply to separate them from ordinary photoperiod strains.

How to grow feminized seeds

Growing cannabis isn’t rocket science, however there are a few basic tips that you can implement to your grows that will make a world of difference to the outcome.

Buy feminized seeds that are high quality

The first and most important rule is to buy feminized cannabis seeds from a reputable source with good genetics such as Marijuana Seed City. Whatever your preference, we have a strain for you, why not browse our highest yielding strains guide and our highest THC strains guide to help you decide.

Start simple with your first grow

Try not to over complicate your setup by using growing techniques such as hydroponics on your first grow. Learn to grow in soil before moving onto other techniques. Growing in soil is by far the most simple and straightforward way of growing cannabis seeds. You can even use a living soil that already contains nutrients so that you don’t have to add anything to your plants and can just focus on the basics.

Use tried and tested germination methods

Buying good quality feminized cannabis seeds isn’t cheap so read up on the best methods of germinating cannabis seeds to give yourself the best start. Use the most basic tried and tested methods such as germinating in between paper towels or a glass of water before planting your seeds. This gives you the best chance of completing your first grow successfully.

Avoid silly mistakes

Avoid common mistakes when you are growing marijuana and not only will your grow produce much better quality weed and yields, it will also be less stressful. Avoid over or underwatering your plants by using smart pots. These clever pots are made with a permeable mesh-like material that allow the roots to breathe and also any excess water to drain which makes it impossible to over water.

Keep your plants happy

Happy plants make good weed, so try your best to replicate the plant’s natural environment as much as possible. To do this you need to:

make sure the temperature and humidity levels are consistently in the perfect range for cannabis plants. Vegetative stage 68 to 77 °F and flowering stage 65 to 85 °F.
