Whereas some cannabis growers don’t mind waiting months to harvest their plants, others prefer to reap the fruits of their labour much faster. Thankfully, many of our cannabis varieties burst from seedlings into mature specimens in a matter of weeks. Fast-growing strains offer a host of benefits; they’re ready before the first frosts outdoors, enable multiple harvests in the same season, help cultivators stay stealthy, and are simply convenient. Whether you’re a small-scale hobbyist growing for personal use or a commercial cultivator in need of a quick turnover, it makes total sense to opt for cultivars that charge through the growing cycle as quickly as possible.

Choosing the fastest strains doesn’t mean narrowing down your options to otherwise lacklustre varieties. On the contrary, fast-growing varieties span across all of our categories, and are available as feminised photoperiod, autoflowering, high-CBD, and F1 hybrid seeds. Check out the very best fast-growing strains from our catalogue below.

F1 Hybrid Cannabis Seeds

F1 hybrid cannabis varieties are available in different forms, including feminised, autoflowering, and high-CBD varieties. They differ from traditional genetics because they are created using pure inbred parent lines. This breeding technique produces true F1 hybrids that boast excellent uniformity, faster growth, larger yields, increased cannabinoid and terpene production, and unparalleled disease resistance. Owing to their stability, these varieties offer an easier alternative to cloning for both commercial and home growers.

  • Epsilon F1 Hybrid

Not only does Epsilon F1 rank as one of our fastest-growing autoflowering varieties, but she matures faster than the rest of our entire F1 hybrid range. If you want unparalleled quality and serious rapidity, then look no further. Our skilled breeders created this variety by crossing two pure parent lines, resulting in a vigorous F1 hybrid with impressive disease resistance and uniformity. You won’t have to deal with any phenos that don’t meet your tastes; they’ll all appear identical.

Epsilon F1’s high THC content and aromatic components merge to create a long-lasting and physically relaxing high. Upon hitting a bong bowl or blunt, you’ll experience a complex yet complementary flavour profile of blueberries and lavender light up your taste buds.

Epsilon F1 maintains a compact size throughout the entire growing cycle, making her suitable for growers who value stealth above all else. Prepare to harvest her frosty flowers in as little as 60 days after popping the seeds.

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.

Feminised Fast Growing Strains

Feminised cannabis seeds are designed to produce only female plants. Feminised 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.

  • Royal Cheese

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.
