⚡ Photoperiod vs. Auto vs. Fast Version — Which Is Right For You?

You’re here

Photoperiod Seeds

Best for: Maximum yield, control, and flavour.

The deal: You control the vegetative stage with your light cycle. Longer veg means bigger plants and bigger harvests. Requires a dedicated flowering space with 12/12.

Choose if: You want to master the craft of growing and push your plants to their full genetic potential.

Autoflower Seeds →

Best for: Speed, flexibility, multiple harvests, and stealth.

The deal: Flowers automatically based on age, not light cycle. Ready to harvest in as little as 8 weeks from seed. No light cycle management required.

Choose if: You want the fastest possible turnaround, have limited space, or want multiple runs per year.

Fast Version Seeds →

Best for: Photoperiod quality with a shorter finish.

The deal: Feminised photoperiod seeds bred to flower 2–3 weeks faster than standard photos. You still control the flip — you just spend less time waiting.

Choose if: You want the yield and quality of a photoperiod but need to trim time off the flowering stage.

Latest Drops: Our Freshest Feminised Strains

Fresh in. New genetics, new flavour profiles, and a few things we’ve been quietly excited about. First in, first served.

🌿 The Benefits of Feminised Photoperiod Seeds

Full cycle control: You decide when vegetative growth ends and flowering begins — flip when your plant is ready, not when a timer dictates.

Higher yield ceiling: Longer veg time means more structure, more canopy, more bud sites. Well-trained photoperiods regularly outperform autos on raw harvest weight.

Training compatibility: Topping, FIMing, LST, mainlining, SCROG — all techniques that need recovery time. Photoperiods give you that time.

Cloning and mothers: Unlike autos, you can take cuttings from a photoperiod plant and preserve genetics indefinitely. Find a phenotype you love? Keep it.

Complex terpene expression: Many of the most aromatic and flavour-forward strains — Amnesia Haze, Durban Poison, Jack Herer — are sativas with long flower times that photoperiod control makes possible.

100% feminised: Every seed in this collection is feminised — guaranteed female plants, zero males to identify and remove, no risk of accidental pollination.

Sativa Dominant Feminized Seeds

Cerebral, energetic, and built for daylight. These are the strains you grow when the effect matters as much as the yield.

Indica Dominant Feminized Seeds

Heavy resin, dense buds, and a body stone that means business. These are the strains you grow when relaxation is the whole point.

🇦🇺 Growing Photoperiod Seeds in Australia

Photoperiod seeds are perfectly suited to the Australian climate — but timing is everything.

Outdoor timing (southern states)

Plant in September–October after the last cold snap. Plants veg through the long summer days and begin flowering naturally as light drops in late summer — typically February onward. Most varieties harvest between late March and May depending on strain and latitude. The Australian sun can produce absolute monsters when you give them a full season.

Northern Australia

The tropical north runs differently. The dry season (April–October) generally works best outdoors. Indica-dominant and shorter-flowering strains handle humid northern conditions better than long-season sativas.

Indoor growing

Complete control regardless of location. Run 18/6 for veg, flip to 12/12 when your plant has the structure you want — most growers aim for 4–8 weeks of veg depending on strain and available height. Factor in the stretch: most plants will roughly double in height after the flip.

Strain selection matters

Pure sativas like Durban Poison and Amnesia Haze thrive outdoors in warm climates but stretch significantly indoors. Indica-dominant strains like Northern Lights and Granddaddy Purple are more compact and faster-finishing — better suited to tents or shorter outdoor seasons. Always check your local laws before cultivating — regulations vary by state and territory.

Balanced Hybrid Feminized Seeds

Versatile genetics, predictable structure, and effects that work across the clock. Hybrids are often the most consistent performers in the tent.

Feminised Cannabis Seed Bundles

Can’t pick just one? Good. Our feminised bundles pair complementary genetics at a discount — tried, tested, and worth growing together.

🌱 The Photoperiod Experience — Why They’re Worth the Wait

We’ve grown a lot of cannabis between us. Autos, photos, fast versions — all of it. And while we stock and genuinely rate a strong autoflower range, there’s something different about running a photoperiod from seed.

It’s the relationship you build with the plant. You’re making decisions the whole way through — when to top, when to train, when to flip. The plant responds to what you give it. A well-vegged, well-trained photoperiod going into flower is one of the most satisfying things you’ll see in a grow room.

The genetics we carry in this collection are all ones we have grown, tested and sampled ourselves.

Take your time. Grow them well. They’ll deliver.

Feminised Photoperiod Seeds — FAQs

What are feminised photoperiod cannabis seeds?

Photoperiod seeds require a specific light schedule to trigger flowering — typically 12 hours of light and 12 hours of darkness. Unlike autoflowers, they stay in vegetative growth for as long as the light period stays above around 14–16 hours, which means you control when flowering begins. Feminised means the seeds are bred to produce only female plants — the ones that develop resinous flowers. The combination gives you guaranteed females and complete cycle control.

What's the difference between photoperiod and autoflowering seeds?

Autoflowers flower based on age — typically 8–10 weeks from seed regardless of light schedule. That makes them faster and lower-maintenance, but it also means less flexibility. Photoperiods stay in veg until you flip the lights to 12/12, which lets you veg longer, run training techniques that need recovery time, and build a bigger plant before flowering begins. Experienced growers often prefer photoperiods because the extra time translates directly into more complex expression and higher yields.

How long do photoperiod strains take to flower?

Most feminised photoperiod strains flower for 8–11 weeks after the light flip. Indica-dominant strains like Northern Lights or Granddaddy Purple tend to finish in 8–9 weeks. Balanced hybrids typically sit around 9–10 weeks. Sativa-dominant strains — particularly haze varieties like Amnesia Haze — can run 10–11 weeks or longer, but reward that patience with distinctive terpene profiles that faster-finishing strains rarely match. Each product page has specific flowering time ranges for that strain.

When should I flip my photoperiod plants to 12/12?

That depends on your space, your training approach, and the strain. As a general rule, plants will roughly double in height during the stretch after the flip — factor that in when growing indoors. Most indoor growers flip somewhere between 4–8 weeks of veg, depending on how aggressively they’ve trained the canopy. Outdoors in Australia, the flip happens naturally as daylight hours shorten in late summer — you’re working with the season rather than a timer.

Can I grow feminised photoperiod seeds outdoors in Australia?

Yes — and Australia’s climate suits it well. In most southern states, plant after the last frost (September–October), veg through the long summer days, and harvest in March–May as the light naturally drops. In the tropical north, the dry season (April–October) generally works better. Sativa-dominant strains thrive outdoors in warm conditions and can reach their full genetic potential with natural light. Always check your local laws before cultivating — regulations vary by state and territory.

What training techniques work best with photoperiod plants?

Photoperiods are well-suited to all major training methods precisely because they have recovery time built into the veg stage. Topping and FIMing encourage multiple main colas rather than one dominant one. LST spreads the canopy for more even light penetration. SCROG works particularly well with vigorous sativa-dominant strains like Moby Dick or Blue Dream that naturally want to spread. The key advantage over autos: if a plant needs time to recover from aggressive training, you give it that time before flipping.

Can I clone photoperiod plants?

Yes — and this is one of the key advantages photoperiods hold over autos. You can take cuttings from a photoperiod plant while it’s in veg, root them, and maintain a mother plant indefinitely. Find a phenotype with exceptional resin, flavour, or structure and you can preserve and run it again and again. Autos can technically be cloned but it’s not practical — a clone carries the same internal clock as the mother and flowers almost immediately after rooting.

How do I store feminised seeds before planting?

Seeds stay viable longest when kept cool, dark, and dry. A sealed container — ideally with a food-safe desiccant pack — stored in a fridge or cool cupboard away from temperature fluctuations will keep seeds in good condition for several years. Avoid freezing unless you’re planning very long-term storage, and let refrigerated seeds come to room temperature before opening the container to prevent condensation. All seeds we ship are stored in climate-controlled conditions and dispatched fresh.
