Automatic vs Feminised vs Regular Seeds: Which Is Right for You?
Share
Introduction
Walk into any seed shop — or browse one online — and you'll quickly encounter three categories of cannabis seeds: automatic, feminised, and regular. Each has distinct traits that suit different growers and growing situations. This guide breaks down exactly what sets them apart so you can shop with confidence.
Regular Seeds
Regular cannabis seeds are the most natural form of cannabis seed. They are produced by breeding a male plant with a female plant, resulting in seeds that have roughly a 50/50 chance of growing into either sex.
Pros of Regular Seeds
- Genetic stability — regular seeds are often preferred by breeders for creating new varieties.
- Hardiness — many growers feel regular plants are more vigorous and resilient.
- Natural growth cycle — they flower in response to light changes (photoperiod).
- Lower cost — typically the most affordable seed type.
Cons of Regular Seeds
- Roughly half your seeds may grow into males, which must be identified and removed before they pollinate your females.
- Less suitable for growers who want guaranteed female plants.
Best for: Experienced growers, breeders, and those interested in seed-making.
Feminised Seeds
Feminised seeds are bred specifically to produce only female plants — the plants that produce the resinous buds most growers are aiming for. This is achieved through a controlled breeding process that eliminates the Y chromosome.
Pros of Feminised Seeds
- All female, every time — no need to sex plants or worry about accidental pollination.
- Better use of space and resources — every plant you grow has the potential to produce a harvest.
- Wide variety available — the vast majority of popular named strains are available in feminised form.
Cons of Feminised Seeds
- More expensive than regular seeds.
- Plants still require a change in light cycle to trigger flowering (unless autoflowering).
Best for: Most hobby growers who want a reliable, fuss-free grow with guaranteed female plants.
Automatic (Autoflowering) Seeds
Automatic seeds — also called autoflowering seeds — contain genetics from Cannabis ruderalis, a subspecies that flowers based on age rather than light cycle. This means they will begin to flower automatically after a set number of weeks, regardless of how many hours of light they receive.
Pros of Automatic Seeds
- Fast finish — most autos complete their life cycle in 8–12 weeks from seed.
- No light manipulation needed — ideal for growers who can't control their lighting schedule.
- Compact size — autos tend to stay smaller, making them great for discreet or space-limited grows.
- Multiple harvests per year — their quick turnaround allows for several grows per season outdoors.
Cons of Automatic Seeds
- Cannot be kept in a vegetative state indefinitely — they will flower regardless, so training time is limited.
- Traditionally lower yields than large photoperiod plants, though modern autos have improved greatly.
Best for: Beginners, outdoor growers, and anyone wanting a quick, straightforward grow.
Quick Comparison Table
| Feature | Regular | Feminised | Automatic |
|---|---|---|---|
| Guaranteed female? | No (~50%) | Yes | Usually yes |
| Flowers based on | Light cycle | Light cycle | Age |
| Time to harvest | 12–20+ weeks | 12–20+ weeks | 8–12 weeks |
| Size | Variable | Variable | Generally compact |
| Best for | Breeders | Most growers | Beginners & outdoor |
Which Should You Choose?
If you're new to growing, feminised or automatic seeds are the most beginner-friendly options. Autos are particularly forgiving — they don't require a strict lighting schedule and finish quickly. Feminised photoperiod strains offer more control over plant size and yield once you're comfortable managing the light cycle.
Regular seeds are best saved for when you have some experience under your belt and are interested in breeding or preserving genetics.
