While patience is a virtue when it comes to growing, you don't have to suffer the pain of waiting. With early finishing outdoor strains, you'll get faster harvest periods for outdoor yields.
This is particularly useful when you need to take advantage of short bursts of fine weather. Temperate climates, for instance, like the UK and Netherlands, benefit from quick growth through warmer spring, summer and early autumn seasons.
Late to the growing season? Then this is what you’re after. You needn't worry about compromises when it comes to these early-finish outdoor strains, either.
You can pick from high-THC varieties that are packed with flavor and loaded with long-lasting effects.
1. Black Jack Autoflower (42-49 days)
Black Jack Auto seeds grow incredibly fast, and they are ready to harvest in just three months. Despite the speedy growth, the buds are not rushed and can produce up to 250g per plant outdoors.
Black Jack delivers balanced effects that relax while also providing a surge of creative energy, perfect for music, poetry, or story writing. This cross of Black Domina x Jack Herer combines fast flowering with substantial yields and versatile effects.
2. Northern Lights x Big Bud Autoflower (42-49 days)
Northern Lights x Big Bud Auto is a top choice if you’re looking to get your hands on a fast-finishing outdoor strain. With a quick flowering time of 42-49 days, this strain is packed with 22% THC and 3% CBD for a solid, balanced experience.
Its earthy, sweet, and citrusy flavor profile will keep things interesting while you enjoy the fast turnover. Plus, it’s potent and pleasant, which makes it a go-to for growers everywhere.
3. Sweet Tooth Autoflower (42-49 days)
Sweet Tooth Auto seeds are a great choice if you want a fast, mold-resistant strain.
With genetics from Afghanistan, Nepal, and Hawaii, Sweet Tooth thrives in warm climates. Despite having a short stature, Sweet Tooth can produce up to 200g per plant outdoors. The big harvest offers sweet, fruity tropical buds.
4. Hindu Kush Autoflower (<49 days)
Hindu Kush Auto seeds are a great choice for the end of the growing season because they flower quickly in less than 49 days.
The entire grow from seed to harvest takes only 2.5 months. You may even harvest in less than 2 months if you're lucky.
In return for the fast grow time, Hindu Kush delivers a bountiful harvest of sweet, woody buds that provide a powerful yet mellow high. This mountain strain has attracted growers since the 1960s for its calming effects.
5. Critical Feminized (42-56 days)
Critical seeds are a good photoperiod option for fast flowering. However, the vegetative time depends on sunlight hours, which diminishes at the end of the season, potentially reducing growth and yield.
Critical offers balanced effects - a relaxing body stone and creative head high from its Skunk and Big Bud genetics. It's also easy to grow.
