Top 5 fast growing cannabis seeds

From time to time, some growers find themselves in a position where they simply need a fast growing, fast flowering cannabis strain which they can harvest in the shortest possible time. If you need fast flowering cannabis seeds, we recommend these top 5 strains. Each will deliver a fast, heavy harvest and high THC levels.

How fast does cannabis grow?

How fast does cannabis grow? When grown indoors under 20 hours of daily light, many autoflower seeds will be ready to harvest around 75 days (10-11 weeks) later. In this article you will hear about autoflower strains that are ready to harvest in as little as 8 weeks. Feminised seeds often take around 14 weeks to grow from seed to harvest. That’s about 5 weeks of vegetative growth followed by 9 weeks of bloom.

For those that grow their own cannabis seeds at home, speed of harvest is often one of the key considerations. Fast flowering cannabis strains tend to be popular. Slow flowering strains may have plenty of great qualities, but they may not be the right choice for you if you need a fast harvest.

Many commercial growers are under financial pressure to complete a crop cycle as quickly as possible in order to start the next crop. Home growers are often more quality focussed. If you’re only growing a couple of crops per year, you may as well grow the best cannabis seeds you can buy. Most growers want a high quality harvest with above average yields. But they also usually want the convenience of a rapid crop.

The following list of Dutch Passion’s 5 fastest flowering cannabis seeds will make it easy for you to grow your own crop in record time.

Bubba Island Kush feminised seeds, as little as 7 weeks in bloom

Indica lovers that want fast flowering seeds will love Bubba Island Kush. These high THC feminised USA cannabis seeds were created by crossing (Grandaddy Purple x OG Kush) with a pre ’98 Bubba Kush reverted male. Plants reach an average indoor height of around 1 metre. Indoor cannabis growers will love the speed of flowering. She can be ready in as little as 7-7.5 weeks of bloom. Precede that with 4 weeks of vegetative growth and you can be looking at a crop of Grade-A Kush in a total time period of just 11 weeks.

The buds grown from Bubba Island Kush seeds are particularly potent with a powerful anti-anxiety high. Medical growers will enjoy strong, relaxing and soothing indica body effects. These fast flowering seeds are part of the exclusive Dutch Passion very high THC cannabis seeds category.

Bubba Island Kush leaves can turn very dark during bloom. This gives her a real hash plant appearance with extremely resinous buds and resin-frosted fan leaves. Concentrate makers will love the deliciously rich terpene profile, perfect for making tasty hash, BHO, wax and shatter.

Bubba Island Kush has an earthy Kush aroma but the sour and fruity tones tend to dominate. The heavily frosted buds are dense and compact. They deliver a relaxing high which is deeply satisfying and enjoyable. Anyone looking for a hard-hitting, fast Indica which produces the best quality buds in the shortest time need look no further. These are the best fast flowering feminised Kush seeds in the Dutch Passion collection.

For those that specialise in quality focussed home growing, few indica strains can match the speed and potency of Bubba Island Kush. This really is fast budding cannabis. Optimise your indoor grow conditions and grow her under LED grow lights for the very best quality harvests.

Optimising your grow room conditions

Bubba Island Kush seeds are part of the ‘USA Special Cannabis Seed’ collection. Expect THC levels of around 20% and a memorable smoke/vape quality. These 20% THC levels are noticeably higher than the average THC levels found in Dutch Coffee shops of around 15-16%. Even ‘premium strength’ Dutch coffeeshop strains (officially measured at around 18% in Dutch Government studies) are not as potent as a well grown Bubba Island Kush.

10 Fast-Growing Cannabis Flowers for Impatient Gardeners

Growing cannabis can be an arduous process. Beyond the space, materials, and nutrients needed, time and light are the most essential ingredients in the cannabis cultivation equation. But what if you’re impatient or short on time? Is there a way to speed up the growing process?

Historically, black market growers would seek out or hybridize strains to harness attributes that catered to their surreptitious needs. These plants would usually be short and stalky with larger-than-average yields, and in some instances they would be autoflowering (such as a ruderalis hybrid). They were designed to be fast-flowering for both a quick turnover and so they could be easily relocated from time to time.

The fast-flowering cannabis strains listed below are now emerging for professional and hobby growers to utilize. They’re perfect for novice growers as well as set-it-and-forget-it growers who want to squeeze out a harvest with little time to spare. The list includes a mixture of both photoperiod and autoflowering varieties so you can find the perfect plants for your setup.

Photoperiod Strains That Grow Quickly (7-9 Weeks)


Lowryder is a hybrid strain that was inbred for nine generations by Joint Doctor Seeds to give it a dwarfed size. Growing no more than 16 inches tall, it’s the cannabis equivalent of a bonsai for the discrete grower’s windowsill or balcony. Lowryder’s small size comes from a species of cannabis ruderalis crossed with Northern Lights #2 and then William’s Wonder. Consumers, be patient with this strain: its medicinal and cerebrally stimulating effects have a slow but powerful onset. A mild earthy aroma radiates from the small, conic buds which autoflower in a short 40 to 45 days. Lowryder is a stalwart plant that can survive in harsh, colder climates, making it a popular strain in northern regions like Finland and Canada.

Critical Kush

Critical Kush from Barney’s Farm is a mostly indica strain that blends together two famed cannabis staples, Critical Mass and OG Kush. Aromatic notes of earthiness and spice usher in a calming sensation that relaxes the mind and body. Critical Kush pairs a staggeringly high THC content with a moderate dose of CBD, making this strain a perfect nighttime medication for pain, stress, insomnia, and muscle spasms. Growers cultivating this strain indoors will wait 50 to 60 days for Critical Kush to complete its flowering cycle.

Early Girl

Early Girl is the wallflower of cannabis strains since its introduction in the 1980s. Lovingly preserved by the breeders at Sensi Seeds, this strain is lazy and relaxed, nothing over the top. A 75/25 indica-dominant hybrid, Early Girl is a good one for those new to cannabis who would like relief from stress. Also a great strain for novice growers, it’s compact, resilient, and has a particularly short flowering time of 7 to 8 weeks. Early Girl grows especially well outdoors, but won’t put up a fuss if she’s stuck inside.

OG Kush

OG Kush makes up the genetic backbone of West Coast cannabis varieties, but in spite of its ubiquity, its genetic origins remain a mystery. Popular myth maintains that Chemdawg and Hindu Kush parented OG Kush, passing on the distinct “kush” bud structure we see in many strains today. However, we can’t be sure because OG Kush first came from bag seed in the early 90s. The earliest propagators (now known as Imperial Genetics) are said to have brought the seeds out of Florida to Colorado and southern California, where it now flourishes. There are many different phenotypes of OG Kush, some of which include Tahoe OG, SFV OG, and Alpha OG.

OG Kush is cherished for its ability to crush stress under the weight of its heavy euphoria. It carries an earthy pine and sour lemon scent with woody undertones, an aroma that has become the signature of OG Kush varieties and descendants. With OG Kush, patients most commonly cite improvements in migraines, ADD/ADHD, and stress disorders.


Superglue is a hybrid strain bred by Seedism Seeds. A cross between Afghani and Northern Lights, Superglue inherits indica growth patterns along with a sweet caramel and pine aroma. Superglue brings calming relaxation to the mind and body, but leaves you functional and energetic enough for social activities or a productive afternoon.

Autoflowering Strains That Grow Quickly (7-12 Weeks)

Red Dwarf

Red Dwarf is a rarer strain of cannabis that is an autoflowering plant. This trait comes from its cannabis ruderalis genetics, which is a third variety of the plant that’s usually not bred due to its lower THC content. The wonders of selective breeding from Buddha Seeds have resulted in seeds that grow to adulthood in an incredibly short six weeks. This strain’s squat, small plants are easy to grow in smaller spaces, making it a popular choice for growers who want something simple and fast. Indica-dominant, Red Dwarf will eventually make you sleepy, but not without some relaxed euphoria first.


Hobbit by Kannabia Seeds is a resilient autoflowering variety with sweetness and strong elemental resistance. This strain has a sweet aroma that has been described as “strawberry candy” and an equally sweet smoke with latent earthy notes. Hobbit deftly combines stimulating Haze elements with a pervasive body buzz that is lightly weighted while remaining pleasant and functional. Many growers covet this autoflowering wonder for its quick 65-day flowering time and above-average yield.

White Ryder

White Ryder is Riot Seeds’ attempt to create a ruderalis version of White Widow by crossing Buddha Seeds’ White Dwarf against Lowryder. By blending two stout, autoflowering plants, Riot Seeds created a potent indica-dominant hybrid that finishes in under 80 days and can easily be hidden from view. Enjoy this flower for anti-anxiety and sleep-inducing effects.

Purple Cheese

Purple Cheese is an indica-dominant autoflowering hybrid that combines Purple #1, Blue Cheese, and Lowryder. Bred by Auto Seeds, Purple Cheese was designed to have a sweeter, less cheesy flavor than its Blue Cheese parent. It does, however, inherit a tight bud structure and a high CBD profile. With a palatable fruit aroma, Purple Cheese delivers powerful full-body effects best suited for night owls or patients treating pain. Colder climates will bring out this hybrid’s purple hues, and for best results, growers should keep this autoflowering variety between 50-80 cm in height.

Royal Haze

Royal Haze (or Royale Haze) by Dinafem Seeds is a mostly sativa strain bred from Skunk, Haze, and Northern Lights genetics. Taking after her Haze parent, this sativa inherits a spicy citrus flavor and buzzing, energetic effects that keep you alert and productive throughout the day. Outdoor growers will appreciate her flexibility and resilience even when the temperature drops, although her 10-11 week flowering cycle demands a bit of patience.

An autoflowering rendition of Royal Haze was bred by Royal Queen Seeds, who mixed Amnesia Haze, Skunk, and a ruderalis strain. Its effects are similarly energizing and cerebral.

Fast Growing Cannabis Strains

Many marijuana strains take 10 weeks or more from planting to harvest time, which is fine if you have plenty of patience, but less good if you’re in a hurry to get your hands on a potent crop of weed. In fact, some strains, especially Sativa dominant types, can take up to 14 weeks or more before they’re ready for harvest, which might try the patience of a saint.

If your principal criterion is speed of growth, then you should probably avoid the Sativa type strains altogether and opt for the Indica types, which mature more quickly. To get to harvest quickest, you’re best advised to grow indoors with the best lighting setup you can afford, using a hydroponic growing medium. The hydroponic method gives you the most precise control of nutrient additives, which can be used to speed up the growth of your plants.

You can also use lighting phases to accelerate growth but exercise caution. If you push your plants too hard, you could end up with straggling monsters of low potency. Once you’ve got your growing regime right, the most important factor in getting a crop to maturity quickly is your choice of strain.

Look out for strains that can mature in from six to eight weeks, with six weeks being about the quickest time you can realistically achieve a good harvest. Some strains to consider include Northern Lights s, a strain much favoured by commercial growers which can flower in as little as seven weeks, The Cheeseh , an Amsterdam coffee shop favourite that can be ready in between six and eight weeks, and Pineapple Kush , another strain that can be ready in eight weeks with the right growing conditions.
