Fast Growing Weed Seeds: Who Are They For?

Actually, when it comes to the fastest marijuana strains, their practical application is much wider than the simple goal of getting to smoke the product as soon as possible. The strains we’re about to present have gained recognition because they save growers in plenty of situations.

High THC Strains

First of all, if you live in a colder region with a short summer but still want to benefit from the perks of outdoor growing, fast-growing weed seeds that achieve maturity in 2 months or even less might be your only option to do so. Then, there are stealthy growers who understand that every extra day of having marijuana plants out is another chance of getting caught, so they value the rapid lifecycle. Moreover, the fastest growing weed usually also stays the most compact, which is another pro for a stealthy grower. Finally, these strains allow for not just one but two outdoor harvests in a single season! So, sometimes, it’s not only about the speed but also the productivity of your crop.

White Widow FAST

Seedsman’s own White Widow FAST seeds combine the photoperiod genes of the legendary White Widow Strain with Fast genetics. The result is a sturdy plant with a flowering time of between just six and seven weeks, meaning all the most sought-after qualities of the classic 1990s strain can be yours a week sooner than they would with the regular photoperiod version.

White Widow FAST is a fairly short indica/sativa hybrid, growing to no more than 120cm. This, coupled with its lightning-quick flowering period make it an ideal strain for growers looking to produce with some degree of stealth. She’ll deliver respectable yields, too – look forward to 350-450 gr/m2 of frosty-looking buds, packing a THC content around the 20% mark. This translates to a powerful effect that begins in the head before moving south to relax the body.

White Widow FAST is just as productive and easy to grow indoors, outdoors, or in greenhouses.

Jack Herer FAST

Another classic strain available with a quick finish, Jack Herer FAST somehow manages to improve on the original by shaving up to a fortnight off the flowering time. That’s right – award-winning cannabis can be yours in just seven weeks! Like White Widow FAST, Jack Herer FAST’s growth will peak at no more than 120cm, yielding around 400 gr/m2 of high-THC buds that positively drip with sugary trichomes.

This is a strain well-suited to indoor growing, but outdoor cultivation will produce equally great results, and plants are ready to harvest before the wetter weather comes in around September.

Jack Herer FAST retains all the desirable qualities of the famed original – expect the unmistakable sweet and peppery Jack taste along with those familiar herbal and pine aromas. It’s a slightly sativa-leaning hybrid with a high-THC content, meaning Jack Herer FAST wraps you in a blissful, euphoric and creative blanket.

Fans of Cinderella 99 and Blueberry will love the hybrid offspring of these favourites, and the fast-flowering version means you won’t have to wait any more than 7 weeks to get your hands on this fruity beauty.

C99 x Blueberry FAST grows quick, but it also takes a stretch, so be sure to allow adequate room to accommodate the significant growth this indica/sativa hybrid needs when she starts to flower. Equally happy growing indoors or outdoors, this strain produces as much as 450 gr/m2 of high-quality bud, generously coated in trichomes. Cultivators will love to hear that C99 x Blueberry FAST has relatively few larger leaves, and as such, trimming is easy.

If you like to indulge your palate with fruity flavours, this strain will delight with its combination of blueberry and citrus tastes. Expect more than a hint of South East Asia from its Thai Sativa genetics, and a high THC content of around 20% is yours after just 45 days. C99 x Blueberry FAST will vanish stress and melt your cares away with its dreamy cerebral effects, and in no time at all, you’ll be floating on a wave of euphoria.

Amnesia FAST

For fans of harder-hitting hybrids, Seedsman’s Amnesia FAST has all the qualities you’re looking for in a quick-growing strain. High THC and high yields make for high times with this impressive plant. Ready after 50-55 days of flowering, Amnesia FAST should be on anyone’s shopping list.

Amnesia FAST combines the genetics original Amnesia strain with a top-secret hybrid, and the results are impressive. It’s a medium-sized plant, coming in at 100-150cm, but that plant produces extremely respectable yields of 550-600 gr/m2 when grown indoors. Buds are dense, and generously packed with an eye-popping 25% THC! She’s just as happy growing outdoors, but leave plenty of space when planting to accommodate the additional growth.

Aroma and taste share some similarities with the original Amnesia strain, but with added fruity and floral notes over and above the spicy haze of its ancestor. The strong cerebral, creative effect from the mostly-sativa genetics, coupled with the outstanding THC content means Amnesia FAST is one you definitely won’t forget!

Black Sugar

For a fast-flowering strain with high yields, high THC and medicinal properties, look no further than Seedsman’s own Black Sugar. In just 8 weeks, this truly unique strain offers up some of the finest traits its parentage has to offer. From Black Domina, we’ve retained the great yield and flowering rate, while keeping the medical properties from L.A. OG and the compact size of the Critical Strain.

Black Sugar is a powerful mostly-indica strain, with a shorter structure that makes it idea for those looking to grow plants quickly with limited space. The yields are among the most impressive around, with 600 gr/m2 common among indoor growers and a superb 800 gr/plant achievable if cultivating outdoors. Buds are generous, and have a sugar-dipped appearance to them

This is a very high-THC strain that offers upwards of 20%, resulting in a powerful, sedative body effect when coupled with the indica properties. For this reason, Black Sugar is an excellent choice as an evening strain to chase away insomnia. A winner with fans of fruity flavours, Black Sugar boasts a taste profile packed full of fruity lemon and orange with a hint of Skunk.

Gorilla Sherbet F1 FAST

Spanish powerhouse Sweet Seeds seed bank brings the heat with Gorilla Sherbet F1 FAST, a high-THC strain bred from Sunset Sherbet and Gorilla Girl XL Auto. The result is a 70% indica strain that can blow your hair back thanks to its THC content, which tops out at around 23%.

Speedy Chile FAST Version

A rapid-flowering, indica-dominant hybrid, Royal Queen Seeds’ Speedy Chile FAST Version combines Green Poison and Chile Indica to stellar effect. This is an easy-growing strain that requires no specific special attention, and the result is an impressive and above-average yield just 8 weeks after germination – that’s two weeks of vegetative, then six weeks of flowering time!

Whether you grow Speedy Chile indoors, outdoors, or under the cover of a greenhouse, you can rest assured you’ll see handsome rewards in a timescale you never would imagine. Yields as high as 500 gr/plant are possible for outdoor cultivators, and indoor growers can look forward to almost the same! It should be noted that Speedy Chile is best grown indoors unless you live in a warmer, Meditteranean-type environment.

Expect a respectable potency from Speedy Chile – THC content is a handsome 16% with very little CBD, resulting in a mellow but uplifting head effect, with some medicinal benefits for insomnia, pain and lack of appetite.

Autoflowering Varieties

2 Fast 2 Vast Auto

If you’re looking for the added ease of Autoflowering properties along with fast flowering times, this one’s worth your attention. Heavyweight Seeds challenged themselves to improve upon their own Fast and Vast strain and did so by adding a Northern Lights Auto to a gene pool comprising White Dwarf and Auto Skunk. The result is a robust plant that gives up its many treasures in just 8 weeks of flowering.

This strain is comfortable growing in any environment and while THC is high at around 20%, makers of extracts and concentrates are sure to be thrilled by the prolific amounts of resin 2 Fast 2 Vast produces – its appearance is positively glistening with crystals. Better yet is the yield – indoor growers can look forward to between 600-800 gr/m2 from this amazingly productive plant.

This is a heavyweight strain from Heavyweight seeds – flavours are fruity to the maximum and a smooth smoke is assured, along with a fantastic, giggly effect that morphs into a long-lasting and relaxed body stone.

Speed Bud Auto

If you’re looking to grow cannabis in record time, you’ll be hard pushed to top Speed Bud Auto for sheer quickness. With a lightning-fast flowering time of just 5 weeks, this small but efficient strain from Female Seeds has few peers when comes to fast-growing cannabis strains.

Touting a diminutive stature of just 80cm, Speed Bud Auto makes a great choice if you’re growing marijuana in a discreet outdoor setting, but is just as comfortable in an indoor environment. Yields are smaller, as you’d imagine, but if sheer flowering speed is what you’re looking for, look no further. As a bonus, this strain is less leafy, meaning manicuring the plant is as quick and easy as growing it!

Speed Bud Auto is a fairly resinous plant but is said to be of lower potency, so if a nice, mellow relaxing effect is your thing, this strain is likely to hit the spot. Enjoy the smooth Diesel taste of this one as you read your speeding ticket!

Star CBD Auto

We wrap up our list of fast-growing cannabis strains with one for the CBD lovers – the Ministry of Cannabis’ Star CBD Auto. Thanks to a rapid flowering time of just six weeks, you can enjoy a strain high in cannabidiol sooner than you may have thought.

Why choose fast-flowering seeds?

Fast-growing cannabis seeds make up a diverse strain category defined by a short blooming stage. And flowering duration can make or break a gardening operation. After all, you can always slash vegging to manipulate the seed-to-harvest period. The same doesn’t apply to flowering. This stage has to run its course for sticky, potent, fragrant weed.

Many specimens of slow-blooming cannabis are worth the wait, but sometimes, you want to switch things up and get buds faster. You’re in the right place to find a massive selection of fast-flowering strains for this purpose. Some are swifter than others due to genetics; others are works of breeding ingenuity. In any case, they’re a blessing for time-sensitive, eager, and cold-weather growers. Start curing your fresh weed in less time — no quality compromised.

Shop with i49 Genetics, and you also get seeds 80% guaranteed to germinate and develop into the finest American phenotypes. You’re not making concessions, just smart yield decisions. Apart from convenience, here are the three reasons cultivators often opt for quick-flowering weed seeds .

Fewer bud rot worries

Bud rot is the bane of cultivators in humid climates. It’s an extension of the classic mold issue, attacking the flowers as they become resinous. Rot reduces your buds to smelly mush, and it’s dangerous to consume. This tricky disease can force you to discard half your harvest.

The longer time plants spend in the blooming stage, the more opportunities bud rot has to strike. It only follows that the risk drops when cannabis is fast-flowering. This benefit applies across the board, but it means the most for growers in tropical regions. Select mold-resistant, fast-flowering seeds for extra security.

Lower costs

Cannabis gardening is expensive. The lights, nutrients, and gadgets to help crops thrive can dent anybody’s budget. Nobody can deny that it’s a worthwhile investment once you’re collecting heaps of sticky buds, but what if you could have both?

Our quick seeds change the game. For one, all top-tier genetics from our shop comes at reasonable prices, cutting costs from the get-go. Once you get growing, you take advantage of the shorter flowering stage. Fast-flowering strains require fewer light hours and nutrients than their slower counterparts. No more sky-high utility bills throughout August and September.

More harvests per season

Fast-flowering seeds don’t only set you up with fresh buds sooner. They can increase how much weed you can get in a limited period. If growing outdoors, you’re working within a set cultivation window. You could spend the entire April–October period tending to one garden of slow-blooming sativa and reap large harvests. You could also mix things up.

Faster-flowering and autoflowering cultivars ripen sooner, freeing the space for the next seed batch. If the summers are particularly long, you might double the harvests of a single growing season. Extra credit for planting different strains and diversifying your stash. Indoor cultivators aren’t so time-sensitive, but they face space restrictions. There are only so many plants that can fit into a spare room. Buy quick-flowering seeds, and that area can generate more pot over the same amount of time. As a bonus, our library holds numerous fast-flowering high-yield strains. How’s that for maximizing return on investment?

Quick flowering marijuana strains to grow

i49 Genetics stocks a rich assortment of fast-flowering cannabis seeds . This category incorporates naturally swift strains and cultivars modified for quicker yields.

Here’s a quick overview of the available variants:

  • Regular quick seeds — photoperiod, male and female, and exhibiting faster blooming periods; usually indica or indica-dominant
  • Feminized quick seeds — photoperiod, all-female, and blossoming in less time; usually indica or indica-dominant
  • Fast version seeds — hybrids between photoperiod and autoflowering strains; displaying photo growth traits but maturing in 2 weeks less
  • Autoflower seeds — ruderalis crosses with automatic growth patterns and reduced seed-to-harvest periods

Fast-growing cannabis seeds come in all shapes and sizes. Get sweet-smelling or spicy buds, uplifting or relaxing properties, no-frills crops, and green thumb challenges.

Not sure where to begin? We’ve hand-picked several notable specimens to accommodate diverse grower and toker preferences. Select a starting point, order the best cannabis seeds in the USA from our shop, and drop the wait from seed to yield.

Fastest flowering indica strains

Many quick-flowering weed seeds from our selection aren’t results of genetic modification. Looking at our feminized and regular varieties, you quickly realize that most originate from the indica family.

Speed is a matter of geography and origins here. Indica landraces that form this family developed in the rough-weather Asian regions; volatile summers influenced their evolution. They flower in around eight weeks, propagating their species before the cold fall days. This trait is present in many modern indica-dominant hybrids, and you can take advantage in any climate. Try these quick seeds from our store for total relaxation and rapid harvests.

Blue Widow feminized

Blue Widow feminized is an indica-dominant Blueberry x White Widow blend with outstanding bag appeal. Oblong flowers, crystalline trichomes, and stunning purple streaks distinguish this 12–17% THC herb.

This fast-flowering strain is strong and stable but quite stretchy. Low-stress training, the right feeding schedule, and cool grow lamps help it ripen to perfection. Yields don’t lack quantity or quality, and blooming takes only 7–9 weeks. Pine scents fuse with berry and citrus in this tasty cultivar. Its soothing touch erases physical and psychological discomfort and encourages wellness-boosting activities—self-care and socialization alike.

Grape Ape feminized

Grape Ape feminized is an indica-dominant cultivar with legendary parentage. As an Afghani x Mendocino Purps x Skunk #1 cross, its 15–25% THC smoke is a medley of flavors and effects. Cultivation is straightforward with these quick-flowering weed seeds . The bushy crop calls for dry, warm environments and regular trimming. Provide the right conditions, and copious yields arrive after 6–8 weeks of blooming.

The name fits the strain—its aromatic bouquet is as sweet as overripe grapes. Notes of skunk and earth underpin the sugary qualities. The smoke is almost medicinal, banishing tension and replacing it with complete comfort.

Fast version indoor strains

Some of our fastest-flowering strains fare best in controlled indoor setups. That holds especially true for autos, which get even stickier and sweeter-smelling when exposed to strong, consistent lamps. What’s more, keeping your crops indoors eliminates climate imbalances from the equation. There’s no stress to recover from, and the output quantity and quality improve. Do you like to keep your garden under complete control? These three strains guarantee prolific indoor cultivation.
