PHOTOPERIOD, ACCELERATED
Fast Version
Cannabis Seeds
Full photoperiod control and the character of the original genetics, bred to finish roughly 2–3 weeks sooner.
THE SHORTER ROUTE, WITH PHOTOPERIOD CONTROL
Not an autoflower. Not a compromise.
Fast Version seeds remain feminised photoperiod plants. You decide how long they vegetate and when they flower by changing the light cycle to 12/12. What changes is the finish: carefully bred lines reach maturity roughly 2–3 weeks sooner than their standard counterparts.
JESS’S DISCOVERY
A wet summer changed our minds
“A forum tip pointed me towards Fast Versions during a late, wet summer. I was sceptical. We tested them for a year, and they absolutely delivered.”
They solved a real timing problem without taking away the control Jess and Jason valued in photoperiod plants. As more customers began asking for the format, the strongest performers earned a permanent place in the Sacred Seeds range.

THE SACRED FAST FIVE
A tight range on purpose
Not every cultivar translates well into a faster format. These five were selected because their defining character remained intact.

The best of both formats
What exactly are Fast Version cannabis seeds?
Fast Version seeds are feminised photoperiod genetics bred to finish sooner than their standard counterparts. They still respond to seasonal or controlled changes in light, giving you the flexibility of a photoperiod with a shorter flowering window.
Most Fast Version lines are developed by introducing early-flowering genetics into an established photoperiod cultivar, followed by careful selection across successive generations. The goal is to preserve the parent strain’s recognisable structure, potency and terpene character while bringing the finish forward.
The exact time saved varies by cultivar and conditions, but Fast Versions commonly finish around one to three weeks earlier than comparable standard photoperiod genetics. For many growers, that is enough to make a meaningful difference when the seasonal window is tightening.
Read the complete Fast Version guideYou still control the timeline
Fast Versions remain light-dependent photoperiod plants, so their vegetative period can still be extended before flowering begins.
Less time waiting for harvest
They are selected to complete flowering sooner, helping shorten the overall calendar without switching to an autoflower format.
The character of the original strain
Well-bred Fast Versions aim to retain the flavour, resin production, structure and effects that made the parent cultivar worth growing.
A strong option for shorter outdoor seasons, late starts, earlier finishes and anyone who wants photoperiod control without committing to the longest possible flowering window.
Australian grower feedback

Fast Version genetics are newer to the Sacred Seeds collection. See what Australian growers are saying about their performance, earlier finish and overall experience.
Great customer service.
Beans popped within 48hrs .
Out of the media on 3rd day been going great ever since.
Big healthy plants very nice structure.
Very happy looking forward to final results in few weeks time .
Choose your format
Fast Version, photoperiod or autoflower?
Feminised photoperiod
You control the length of vegetative growth and decide when flowering begins. That flexibility creates the greatest potential for training, plant size and yield—but usually requires the longest overall timeline.
- Flowering trigger
- Shorter light cycle
- Typical flowering
- Approximately 8–10+ weeks
- Best suited to
- Control and maximum potential
Fast Version
You retain photoperiod control while growing genetics selected to flower sooner. Fast Versions offer a useful middle ground for growers who want an earlier finish without moving to an automatic lifecycle.
- Flowering trigger
- Shorter light cycle
- Typical flowering
- Approximately 6–8 weeks
- Best suited to
- Photoperiod control with speed
Autoflower
Flowering begins according to plant maturity rather than a seasonal or controlled light change. Autos generally offer the shortest overall lifecycle, but provide less control over vegetative growth and final size.
- Flowering trigger
- Plant maturity
- Typical lifecycle
- Approximately 8–12 weeks total
- Best suited to
- Speed and compact structure
Timings are general guides rather than guarantees. Actual flowering time, lifecycle and final performance vary by cultivar and growing conditions.
Built for a shorter window
Fast Version seeds in Australian conditions
Queensland, Northern NSW and warmer Western Australia
Longer periods of warm weather provide the greatest flexibility. An earlier-flowering photoperiod can help shorten the time each plant remains exposed to summer humidity, heavy rain or changing late-season conditions.
Sydney, the ACT, Adelaide and temperate coastal regions
In temperate climates, the value of a Fast Version often becomes apparent near the end of the season. Finishing earlier can reduce exposure to cooler nights, autumn rain and the increasing uncertainty of late-season weather.
Victoria, Tasmania and cooler elevated areas
A shorter flowering period can be particularly useful where cold nights, frost or persistent rain arrive earlier. Fast Version genetics broaden the range of photoperiod cultivars that may fit within a more restricted seasonal window.
Regional guidance is a starting point, not a fixed calendar. Elevation, local microclimate, cultivar and year-to-year weather can matter as much as latitude.
Fast Version essentials
Fast Version seeds, explained
Clear answers about flowering behaviour, expected timings and how Fast Version genetics compare with standard photoperiods and autoflowers.
What are Fast Version cannabis seeds?
Fast Version cannabis seeds are feminised photoperiod genetics bred to flower sooner than their standard counterparts. They retain the light-dependent flowering behaviour of a photoperiod plant while offering a shorter flowering window.
Are Fast Version seeds the same as autoflower seeds?
No. Autoflowers begin flowering according to plant maturity and do not require a seasonal or controlled light-cycle change. Fast Version plants remain photoperiod dependent, giving the grower greater control over the length of vegetative growth and when flowering begins.
How much faster are Fast Version seeds?
Fast Version cultivars commonly finish around one to three weeks sooner than comparable standard photoperiod genetics. The actual difference varies by strain, environment and growing conditions, so the timing listed on each product page should be treated as a guide rather than a guarantee.
Are Sacred Seeds Fast Versions feminised?
Yes. Every Fast Version variety in the Sacred Seeds collection is feminised and bred to produce female plants. “Fast Version” describes its earlier-flowering photoperiod behaviour, while “feminised” describes the sex it is bred to produce.
Why choose Fast Version rather than standard photoperiod seeds?
Fast Versions suit growers who value photoperiod control but want an earlier finish. They can be particularly useful when the available seasonal window is limited, a grow begins later than planned or late-season weather creates additional risk.
Are Fast Version strains suited to Australian conditions?
They can be useful across many Australian climates because an earlier finish may reduce exposure to autumn rain, cold nights, humidity or frost. Their suitability still depends on the individual cultivar and local conditions; Australia’s tropical, temperate and cool regions require different planning.
Can Fast Version plants be cloned?
Yes. Because Fast Versions are photoperiod plants rather than autoflowers, they can be maintained in vegetative growth and cloned in the same way as other photoperiod genetics.
How should Fast Version cannabis seeds be stored?
Store seeds in a cool, dark and dry environment away from sunlight, heat and moisture. For longer-term storage, use a clearly labelled airtight container and avoid repeated changes in temperature.
