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.

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.
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.
Autoflower Bubblegum is a mouthwatering indica-dominant hybrid. It’s a revamp of the award-winning herb from the ‘80s, delighting sweet-tooth tokers and knocking socks off with 15–23% THC. Barring moisture sensitivity, these fast-flowering cannabis seeds develop into sturdy plants. Employ standard gardening practices, prune with care, and keep the grow lights running. Flowering takes around five weeks indoors and yields surprisingly high harvests.
The buds are palate pleasers, emanating tropical fruit and ripe berry aromas. The sugary smoke delivers a heavy-hitting, happy, and creativity-boosting effect profile. It also induces full-body tranquility that leaves you grinning from the depths of your couch cushions.
Autoflower Cheese is an indica-dominant cross between Critical + auto and the original Cheese. This new version delivers moderate THC levels (up to 15%), but the smoking experience is no less spicy and intense.
This fast-flowering strain is tough, resisting common cultivation pitfalls with ease. Its tiny crops require 18 hours of light and a standard feeding regimen to produce a mass of gluey buds. As a bonus, flowers take mere five weeks to ripen. Blue cheese, fruit, and earth create a multi-layered sensory experience upon consumption. Once the THC hits, lingering tension dissipates from the brain and body. You’re lucid enough for hobbies but too lazy to move and groove.
Bruce Banner fast version
Cultivators took the Incredible Hulk of cannabis and a secret hybrid to create Bruce Banner fast version . This rendition of the epic cultivar is indica-dominant and super-powerful, landing a punch of 25–32% THC. These fast version seeds grow into female, photoperiod, vigorous crops. Training techniques pair well with their tall, slender branches; generous feedings kickstart bud production. Yields are bountiful after 7–8 weeks of flowering.
Sugar fuses with diesel in this strain’s flavor profile. A mosaic of mind-and-body effects follows, starting with an energy rush and ending in deep relaxation. Creativity and euphoria remain present throughout.
Fastest-flowering outdoor strains
Do you want to see nature work its magic on your ganja? Many fast-growing weed seeds produce the highest-quality results under natural sunlight.
The weather plays a major role if you choose this growing style. Go for hardy plants that don’t mind temperature shifts, letting you use the earth’s resources for the cultivation journey. The following three strains are perfect examples — no-frills, super-resistant, and high-yielding. Get these seeds, use the summer heat, and smoke sun-grown weed in no time.
Candy Kush feminized
Candy Kush feminized is an indica-dominant hybrid with 14–19% THC. Combining OG Kush and Trainwreck, it displays traits of both weed families. It’s easily the best quick-flowering seed for a two-in-one growing and smoking experience. These crops are incredibly resinous and a true pleasure to grow. They’re anything but fussy, too, reaching medium heights and resisting mold and pests. They love organic soil, producing heaps of buds underneath natural sunlight and becoming harvest-ready in 9–10 weeks.
This flower emits fragrances of ripe summer fruit against an earthy base. The smoke brings a full-body buzz, unrelenting mental euphoria, and complete physical tranquility. The munchies are an inevitable part of the ride.
Big Bud fast version
Big Bud fast version is an indica-dominant strain with 14–17% THC. Breeders blended the original with mysterious non-photoperiod genetics, accelerating growth while maintaining its top selling points. These fast-growing weed seeds are still cultivator favorites.
As the name suggests, the crop carries massive, chunky, resin-covered flowers. It’s also hardy, suiting all environments and growers of any experience level. Phosphorus-heavy feeding and strong lamps are optimal. It blooms in 6–8 weeks and produces hefty harvests. Smells of ripe fruit and unmistakable Kush earthiness ooze from these flowers. They induce a balanced set of physical and cerebral effects, eliminating negativity and encompassing you in head-to-toe relaxation.
Critical Jack feminized
Critical Jack feminized is a Critical + x Jack Herer cross and the only sativa-dominant cultivar on our list. It delivers 15–20% THC, robust plants, and the quintessential tropical weed energy.
Although unmistakably sativa in appearance, this fast-flowering strain displays indica growth traits. It’s hardy and resilient, pest-resistant, and insusceptible to mold. Its high flower-to-leaf ratio promises abundance after 8–9 weeks of blooming. The bouquet is a concoction of delectable flavors. Pine, lemon, pepper, and spices come together to enchant your senses. Several puffs get the good vibes going, supply the motivation to tackle tasks, and underpin the power with peace.
