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 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 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 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 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 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 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 (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.
These fast-flowering cannabis strains are 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.
Top Fastest Growing Cannabis Seeds By Categories (2020 Update)
Choosing the right seeds is the first most important part of a successful grow. These selections from Autoflowering, Feminized and CBD plants are our most popular fast growing strains. They are easy to grow, produce good yields and deliver the goods all the way.
Cannabis cultivators look for specific traits when selecting a strain. Some search for flavour and potency above all else, whereas others are more concerned with speed. Luckily for both the former and latter camps, the breeders at Royal Queen Seeds have dedicated a lot of time to developing top-quality strains that are quick off the mark and rapid to deliver their goods.
Our team has created both fast-flowering feminized genetics and autoflowering genetics to satisfy all types of growers. The former offers all the benefits of photoperiod strains, but with a reduced flowering time.
Our autoflowering varieties, on the other hand, are the fastest in our archive. Infused with Cannabis ruderalis genetics, these cultivars don’t require external cues to flower. Instead, they surge from seed to harvest in a matter of weeks, making them perfect for stealthy home growers.
Let’s explore the fastest RQS cannabis seeds by category. Though the following timeframes are approximations, they are accurate.
Autoflowering seeds can be both sativa and indica. However, they have been crossed with a type of cannabis called ruderalis. This enables them to flower on their own in as little as 2-4 weeks without exposing them to strict 12 hour light regimes.
Some of our most popular strains in this category include:
Quick One is one of the fastest auto-growing strains on the planet. The plant is based on the original auto flowering strain – Lowryder. This strain was created from a cross between William’s Wonder x Northern Lights x Ruderalis. These plants are usually ready for harvest in 8 weeks from germination. The plants also reach between 50 and 60 cm and can yield up to 150g per plant.
|Lowryder 1 x Old School Indica|
|275 – 325 gr/m2|
|50 – 60 cm|
|5 – 6 Weeks|
|Sativa 10% Indica 60% Ruderalis 30%|
|100 – 150 gr/plant|
|60 – 100 cm|
|9 – 10 weeks after sprouting|
Easy Bud received her name for good reason. As well as being one of the easiest cannabis strains to grow, she also boasts one of the fastest growing cycles. Her speedy and robust nature makes her ideal for those seeking a fast turnover, and those ready to take their first step into the world of growing weed.
As the progeny of White Indica and ruderalis, Easy Bud produces frosty flowers featuring a THC content of 12% alongside citrusy and earthy terpenes. These buds won’t blast you to the moon, but they will offer a soothing and subtle effect perfect for any time of day.
After germinating these seeds, Easy Bud will explode into a mature plant in as little as eight weeks. Prepare to harvest up to 325g/m² from indoor plants, and between 30–80g/plant from outdoor specimens.

Not only does Royal Bluematic offer quick results, but she also delivers aesthetically stunning flowers and relaxing body highs. This strain emerged after Royal Queen Seeds crossed the legendary cultivar Blueberry with a high-performing ruderalis variety. Thus, they took the best traits of this classic and made them much easier and faster to cultivate.
After placing her seeds in the soil, growers should be prepared to harvest her bud within a timeframe of 8–9 weeks. Such impressive speed makes her a great candidate for guerrilla growers looking to stay below the radar.
Royal Bluematic blooms colourful buds boasting shades of orange, green, purple, and yellow, as well as a THC content of 14%. Her phytochemical mix provides a stoning high augmented by sweet and earthy flavours.
|Blueberry x Ruderalis|
|425 – 475 gr/m2|
|60 – 75 cm|

FEMINIZED FAST GROWING STRAINS
Feminized cannabis seeds are designed to produce only female plants. Feminized seeds will produce a female plant 99.99% of the time. Don’t waste your time trying to produce flower from a male plant – they will only pollinate you females, resulting in seeds rather than bud.
Fast Flowering strains are hybrids of these and autoflowering strains. They are genetically coded to produce flowers quickly with little care, but still rely on a change in photoperiod to flower.
Some of our most popular selections in this category include:
CANDY KUSH EXPRESS
As well as offering a rapid flowering time, Candy Kush Express is a rich source of terpenes, emanating notes of sugary sweet citrus. Her speed of growth and incredible taste make her a great strain for cannabis chefs who want a crop that yields well on a regular basis. This strain features a close balance of 60% indica genetics and 40% sativa, which exerts an effect that relieves tension from the body while keeping the mind alert and functional.
Candy Kush Express is a speedy photoperiod variety that features a flowering time of only 7–9 weeks. Plants grown indoors under good-quality lights will yield up to 525g/m². Those grown outdoors are capable of yielding between 450–500g/plant.
