Top 6 Fast-Growing Strains for Impatient Growers
Patience is a virtue that many growers lack. Who has the time to babysit a grow for months on end? Some growers treat their cannabis like bonsai, journaling every stage as if it were a sacred ritual. The rest of us are refreshing calendars and sneaking peeks long before flowers have even formed. If that sounds like you, welcome: fast-growing cannabis strains are your new best mate.
Thanks to clever breeding, you can now grab feminised seeds and autoflower genetics that mature at a pace to match even the twitchiest grower.
And because we don’t mess around, here’s the Amsterdam Seed Center shortlist: six strains that deliver speed, flavour, and yield without dragging their feet.
1. Royal Gorilla Auto – Royal Queen Seeds
Royal Gorilla is a resin monster with a reputation for flattening even seasoned smokers. The autoflower genetics version retains all that raw power but operates at a faster pace. Expect dense, sticky buds coated in trichomes, harvest-ready in just 8–9 weeks from seed.
The terpene profile leans earthy and piney with a citrus kick, while the high is full-body chaos — couch-lock one minute, creative spark the next. Royal Gorilla Auto is the definition of top-shelf potency without the long wait.
2. Green Gelato Auto – Royal Queen Seeds
Dessert just got quicker. Green Gelato Auto keeps the sweet, creamy flavour of the original and slashes the flowering time. This indica-dominant hybrid delivers jars of smooth, balanced buds in just 9 weeks.
It stays compact, turns around fast, and leaves your grinder smelling like an Italian ice cream shop. Green Gelato Auto is indulgence on a timer — flavour first, patience not required.
3. Gorilla Glue Auto – Barney’s Farm
Gorilla Glue Auto is not subtle. Barney’s Farm took their version of the legendary Glue and pushed it into rapid-fire autoflower mode. It is a 55% indica hybrid with a fast cycle and serious yield potential, listed at up to 600 g/m² indoors.
The terpene profile screams coffee, cream, and earthy funk. This is the jar you open and immediately regret if you were trying to be discreet.
The high is intense, heavy, and long-lasting. Expect body melt, tunnel vision, and the sudden realisation that standing up might be optional. For impatient growers who still want that “one and done” evening smoke, Gorilla Glue Auto is about as forgiving as a sledgehammer.
4. Auto Blue Cheese – The Original Big Buddha Family Farms
Gorilla Glue Auto is not subtle. Barney’s Farm took their version of the legendary Glue and pushed it into rapid-fire autoflower mode. It is a 55% indica hybrid with a fast cycle and serious yield potential, listed at up to 600 g/m² indoors.
The terpene profile screams coffee, cream, and earthy funk. This is the jar you open and immediately regret if you were trying to be discreet.

5. Royal Critical Automatic – Royal Queen Seeds
Royal Critical Automatic is Critical with the fuss removed. Same dependable structure, shorter waiting time. These feminised autoflower seeds typically go from seed to harvest in about 9 weeks, with a very short indoor flowering time of around 6–7 weeks.
The terpene profile leans sweet, skunky, and woody — that old-school “proper weed” aroma that fills a room instantly. The effect is calm and body-heavy without knocking you unconscious, which makes it a good option for evenings or lazy weekends.
Plants stay short and bushy, so they suit balconies, small tents, and anyone who does not want a jungle on display. Royal Critical Automatic is the definition of plug-and-play: minimal training, quick turnaround, reliable results.
6. Auto Blackberry Kush – Dutch Passion
Purple, compact, and Kushy as hell. Auto Blackberry Kush is a mostly indica autoflower that finishes in about 10 weeks from seed, often a little quicker indoors under stable light.
These feminised autoflower genetics grow into short, chunky plants with a big central cola and thick side branches. Most phenos throw deep purple tones by harvest, so the buds look like they belong in a boutique jar, not a rushed grow.
The terpene profile is a rich blend of fruity berry, earthy, and pine notes, classic Kush with a sweet twist. Effects lean into a strong body stone with a mellow, euphoric lift at the start – ideal for evenings, films, and shutting the day down properly.
If you want a fast indica-dominant autoflower with colour, flavour, and no drama, Auto Blackberry Kush earns its spot in the impatient grower hall of fame.
Quick Tips for Quick Strains
Fast genetics give you an edge, but you still need to keep things tight:
- Pick feminised seeds or autoflowers from trusted breeders — no wasted time on duds.
- Keep the environment steady. These strains don’t have weeks to bounce back from mistakes.
- Go easy on the feed. Compact plants don’t need heavy doses.
- Harvest on time. Fast strains can swing from perfect to overripe before you’ve blinked.
