It can be a little overwhelming to begin to choose your cannabis seeds. Obviously having some experience as a consumer makes a difference. However, the transition from user to successful hobby grower does not happen overnight. It takes trial and error, research, and a few experiments.

That said, getting in the right ballpark is easy to achieve with a little research. The following is a brief overview of some of the most popular strains for a home grow. We cover each category of cannabis seed with fast strains - although, you will see some crossover with autoflowering genetics.


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.

Royal Critical Automatic is a well known auto that has gained impressive traction within growing circles after winning numerous awards in Spain. She’s easy to cultivate, grows with immense speed, and provides a mellow high. These traits make her popular among both beginner and veteran growers. Her indica-dominant genetic makeup provides a physical high that is deeply relaxing and meditative. She’s a great smoke for quiet evenings in, and during camping trips when relaxing under the stars. A THC level of 14% makes for a clear-headed and subtle high.

Royal Critical Automatic was created when breeders combined Critical with a robust ruderalis strain. The result is a compact plant that produces tight and resinous flowers 8–9 weeks after germination. Indoor plants maintain small and stealthy heights of 55–65cm and put out impressive yields of 350–400g/m². Outdoor plants grow to a height of 140cm and produce a harvest of around 165/plant.

Royal Gorilla Automatic represents the elite of autoflowering cannabis genetics. She was forged in the breeding room using Gorilla, Cookies, and ruderalis genetics. She moves like a lightning flash and will have a bounty ready to harvest in as little as 8 weeks after germination, a trait that greatly appeals to commercial and impatient growers alike. She also contains a THC level of 20%, a quantity rarely witnessed in autoflowering varieties. The indica-dominant nature of this cultivar dumps a heavy and soothing high atop the entire body, leaving no muscle untouched.

Another trait that places Royal Gorilla Automatic leagues above many other autos are her heavy yields. Plants grown indoors will reach a height of between 60–120cm and yield up to 400g/m². Plants cultivated outdoors will grow taller, up to 140cm, and produce a satisfying yield of up to 170g/plant.

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:


As well as offering a rapid flowering time, Candy Kush Express is a rich source of terpenes, emanating notes of sugary sweet citrus.

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.

This plant of British origin draws its heritage from the top-rated skunk developed on the isle. Since then, the Cheese genetic has spread globally and even won a Cannabis Cup. The plant will grow to about 1.5 meters indoors. It is highly odiferous, however. So much so that a carbon filter is definitely required. Royal Cheese can be harvested after 6-8 weeks and yields up to 550 grams per square meter. The smoke from the cured bud is strong and aromatic. However, it is the strength of the strain that keeps coming back.

This includes health-conscious foodies and even endurance athletes.
