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
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
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.

EASY BUD
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.

ROYAL BLUEMATIC
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.

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.

Top 6 Fastest-Growing Cannabis Seeds
Check out these 6 strains if you’re looking for speed. This mixture of autoflowering and feminized photoperiod strains will race through veg and bloom to deliver a yield with immense flavours and potent effects.
Cannabis strains have been selectively bred over the years to produce specific, desirable traits. Some breeders aim for sheer potency and try to promote max THC levels. Others focus on the therapeutic effects of the herb, attempting to increase CBD and terpene concentrations. However, there is one demand that will always exist among all cannabis growers: speed.
Speed is an important aspect to many different kinds of growing operations. Commercial growers value this trait because of the fast turnover. Discreet growers and guerrilla growers develop a taste for speed as it allows them to begin and end their operation as fast as possible. Below are 6 of the fastest-growing cannabis seeds.
FAST AUTOFLOWERING STRAINS
1. VANILLA ICE AUTOFLOWERING
Vanilla Ice Autoflowering was crafted using the original Vanilla Ice along with a ruderalis strain. Ruderalis genetics are primarily included for their autoflowering traits, with speed of growth being a massive bonus in many strains. Here too, ruderalis delivers the goods, whereas Vanilla Ice transferred her fresh, sugary, and vanilla flavours and indica-dominant genetics. Her THC level of 13% provides a soft and gentle high that is easily manageable, even after several joints and bong hits. She’s perfect for complete novices and those who don’t get along too well with sky-high THC levels.
Vanilla Ice Autoflowering produces impressive harvests of tall and narrow buds within a short time frame. Both indoor and outdoor crops will be ready to harvest a mere 55–65 days after germination. Indoor plants grow to around 60–90cm, making them easy to conceal, and produce a harvest of up to 350g/m². Plants grown outside will remain stealthy among the undergrowth at heights of 50–100cm, yielding 100–175g/plant.
2. CANDY CARAMELO
As her name suggests, Candy Caramelo is known for more than just her brief grow cycle. The trichomes of this strain truly work overtime pumping out terpenes that merge to create mouthwatering flavours of mint, caramel, and sugar. Utilising simple extraction methods such as cannabutter allows users to craft sweet edible delights that are irresistible. Smoking this flower brings on a stoning indica high that soothes the body and induces a chill state for a couple of hours.
The flowers of Candy Caramelo are small, compact, and tapered. But don’t judge them by their size. Each toke is infused with unparalleled flavour and a THC level that hovers around 15%. Expect a yield of 300–350g/m² and a height of 75cm when growing this strain indoors. Alternatively, outdoor plants will pump out 220g/plant and max out at a height of 120cm. Growers don’t wait long to taste these flavours; she’ll be ready to trim as little as 50 days after germination.
3. NORTHERN LIGHTS XL AUTOFLOWERING
Northern Lights XL Autoflowering ticks almost all of the boxes that autoflowering growers are looking for. She offers a good yield, fast flowering time, decent potency, and brilliant aesthetics. To make this possible, the legendary Northern Lights XL was bred with a ruderalis strain, a move that saw highly prolific and legendary genetics shift over into the auto realm. This lady offers a chill and mellow indica high fuelled by a 14% THC level and tastes and aromas of sweetness and citrus.
This speedy specimen pumps out gorgeous flowers that are narrow, tall, and feature shades of green, grey, light purple, and white. When grown indoors, she’ll ascend to a height of around 120cm and yield up to 400g/m². Outdoors, she’ll grow to a taller height of 150cm and deliver up to 230g/plant.
FAST-GROWING FEMINIZED PHOTOPERIOD STRAINS
4. WHITE CHEESE
White Cheese was forged in the grow room using the reliable and productive genetics of Afghan and Skunk. This merging created a fast-flowering delicacy with a rich taste of spice and cheese, and a physical indica high that’s ideal for experiencing in the late evening thanks to its sedating qualities at high doses. A THC level of 17% places her on the more mellow end of the spectrum; it’s enough to induce relaxation without catapulting the smoker into a hazy state of paranoia and overwhelm.
White Cheese will be ready to dry and cure within a brief flowering time of 50 days, reaching a manageable height of up to 90cm and yielding 350–450g/m² indoors. Outdoor plants put out satisfying yields of 150–220g/plant and achieve a maximum height of 120cm.
5. POWER PLANT XL
The highly efficient and extremely productive genetics behind this strain are derived from South Africa. Power Plant XL is known for her massive yield that is conveniently paired with fast-paced growth. Growers will watch the plant flower for around 55 days until they can begin drying, curing, and sampling the fruits of their labour. What’s more, this sativa-dominant lady produces a THC level of approximately 20%. The terpene profile within the flowers augments this experience with flavours of sweet, sour, and pine.
Power Plant XL doesn’t mess around; it’s almost like she wants to be smoked as quickly as possible. These flowers appear on indoor plants in quantities of 600–750g/m², with specimens reaching just over a metre in height. Plants grown outdoors in Mother Nature’s embrace will provide a mammoth yield of up to 600g/plant and peak at a height of around 200cm.
6. LEMON KUSH
Lemon Kush offers an incredibly tangy citrus hit delivered alongside a THC level of 18%. This zesty and refreshing profile complements the indica high well by adding an edge of stimulation and alertness. This interesting combination came about as breeders matched parent Strains Chemdawg, Lemon Thai, and Pakistani Kush. These desirable traits are available to growers after a short flowering time of approximately 55 days.
Lemon Kush isn’t fussy, growing with ease in both indoor and outdoor environments. Indoor plants grow to a height of between 100–130cm and easily yield up to 500g/m². In comparison, outdoor plants top out at 230cm and yield between 450–550g/plant.
Speed is an important factor in cannabis cultivation, and these 6 seeds fit the bill perfectly whether you're a novice or an experienced hand.
