Frequently Asked Questions

What are feminized cannabis seeds?

Feminized cannabis seeds are bred to produce almost exclusively female plants, typically around 99% of the time. Since only female plants produce the resin-rich buds growers want, feminized seeds remove the guesswork of sexing plants and growing out unwanted males.

How are feminized seeds made?

Breeders trigger a female plant to produce male pollen sacs, usually by spraying it with colloidal silver during early flowering, which disrupts the plant's hormone signaling. That pollen carries only female genetics, so pollinating another female with it produces seeds that grow into female plants.

What are the main advantages of growing feminized seeds?

Every seed has a strong chance of becoming a bud-producing female, so you don't waste time, space, lights, or nutrients raising males you'll have to discard. This makes planning your grow simpler and more space- and cost-efficient.

What's the difference between feminized and autoflower seeds?

Feminized (photoperiod) seeds need a light-cycle change to flower and generally take longer to mature (roughly 12-20 weeks), but tend to grow larger and yield more. Autoflowering seeds flower automatically based on age, finishing faster (about 7-12 weeks). Most modern autoflower seeds are also feminized.

What germination and success rates can I expect from feminized seeds?

Fresh, properly stored feminized seeds from a reputable seed bank typically germinate at a 90%+ rate and produce female plants around 99% of the time. Seeds usually sprout within 24-72 hours under warm, moist conditions.

Are feminized seeds good for beginners?

Yes, feminized seeds are one of the most beginner-friendly options because they remove the need to identify and cull male plants, leading to more predictable growth and fewer surprises.

Do feminized plants produce their own seeds?

Not usually, since there's no male plant present to pollinate them. However, significant stress (temperature swings, light leaks, physical damage, or nutrient problems) can trigger a female plant to develop hermaphroditic traits and self-pollinate.

How should feminized seeds be stored, and how long do they stay viable?

Store feminized seeds in a cool, dark, dry place, ideally in an airtight container in a refrigerator. Properly stored seeds commonly remain viable for 2-5 years, though germination rates gradually decline the longer they're kept.

Schon mehrfach bei RQS bestellt und stets zeitnah beliefert worden. Alles kam gut verpackt und heil bei mir an, die qualität der Produkte selbst ist immer erneut bestens. Bei der letzten Bestellung wurde etwas falsches geschickt. Der Kundenservice hat zügig geantwortet, und Ersatz lag unverzüglich in der Post. Von meiner Seite aus nix zu beanstanden! :-)
