Auto Seeds is a London-based seedbank that has bred nothing but autoflowering feminized seeds since 2008, and growers searching for autoseeds usually mean this catalogue; the breeding work is carried out in Spain and the Netherlands. The nine strains here run 18% to 24% THC content and 8 to 12 weeks flowering time from seed, seven of the nine rated easy for indoor and outdoor cultivation. Named picks include GG#4 Auto, Hijack and Auto Pounder. If pure autos feel limiting, the complete seed collection adds photoperiods and regulars to the mix.
By crossing their original dwarf plant, Auto #1, with two established, high yielding and potent strains - Big Bud and Power Plant - breeders from Auto Seeds managed to improve the harvest of their AutoFem strain. Get 600 g from square meter after just 70 to 80 days with Auto Pounder!
Trying to improve something that is already perfect is not an easy task. The breeders at Auto Seeds took two famous strains with a number of dedicated users and tried to make an autoflowering, feminized strain with characteristics of both, but quicker. Tried, and succeed. Hijack!
Combining the medicinal power of Blue Dream with the succulent and mouth-watering flavours of Berry Ryder, Dreamberry is a one-way ticket to fruity sedation. She packs a powerful punch, rocketing the mind while easing the body into a strong buzz. Dreamberry is also a great producer, having the potential to yield 350g/m² and go from seed to harvest in 70-75 days.
One of the strongest autoflowering strains ever developed. Mixing Auto #1 (Lowryder and Ruderalis) genes with the White Russian (AK-47 and White Widow), notorious for its unbelievably high THC content, exceeding 20%, had to produce a killer weed. With Auto Seeds feminized Trans Siberian you can have the same...
The feminized Candy Kush by Auto Seeds is a sweet little, yet big yielding, autoflowering variety with a high resistance to mold and pests. The plants have a short and sturdy, bushy growth structure and stay as little as 50-60cm indoors, but they produce a generous amount of highly potent weed. The smoke has a deliciously sweet taste and will knock you out - ideal for chilling.
Sucker Punch is an autoflowering knockout. It’s a crossing between a Pre98 elite cutting of Bubba Kush and Candy Kush, one of Auto Seeds' best sellers. It goes without saying that potency is at remarkable levels, but it’s also the versatility and basic growing traits that make Sucker Punch a very good choice. Plants will stay compact, with heights of 60-80cm. Ready for harvest in 65-70...
Auto Chemdog is a feminized autoflowering hybrid strain by Auto Seeds. As many other Auto Seeds creations, Auto Chemdog has excellent growing traits—a lifespan of 60–65 days and an average yield of 280–350g/m². The strain can be fully appreciated once smoked. The high is a mind-altering experience with a strong reflexive cerebral effect, followed by full body relaxation.

Auto Seeds has done one thing since 2008: autoflowers. No photoperiod line, no side projects. The head office sits in London and the breeding runs in Spain and the Netherlands, which is how a British brand ends up with Mediterranean field work behind it. Growers searching for autoseeds usually land on this exact catalogue.
A cannabis ruderalis ancestor is what makes these plants flower on age rather than on light, so an 18/6 light schedule can run start to finish and you never flip to 12/12. Every one of the nine strains here is feminized, so there is no sexing either. Both traits together are what makes autoflowers the standard beginner recommendation for indoor growing.
Nearly two decades on a single seed type is unusual. Most banks spread across photoperiod, feminized and regular lines; this one narrowed instead, and the nine strains stocked here are the result of that focus rather than of a broad catalogue.
| Strain | THC | Seed to harvest | Indoor yield |
|---|---|---|---|
| Girl Scout Cookies | 24% | 10-11 weeks | Up to 650 gr/m2 |
| GG#4 Auto | 23% | 10-11 weeks | Up to 600 gr/m2 |
| Hijack | 22% | 11-12 weeks | High |
| Auto Chemdog | 20% | 8-9 weeks | Up to 350 gr/m2 |
| Auto Pounder | 18% | 11-12 weeks | Up to 600 gr/m2 |
Girl Scout Cookies leads on both THC content and yield. Auto Chemdog is the sprinter at 8 to 9 weeks from seed, three full weeks ahead of Auto Pounder and Hijack.
A photoperiod plant waits for you to drop the light to 12/12; an autoflower starts flowering on its own schedule. You trade control for simplicity, because you cannot hold an auto in veg to grow it larger. For a short outdoor season that trade is usually worth making.
Seven of the nine are rated Easy, which is the real argument for this brand. Trans Siberian and Sucker Punch both finish in 9 to 10 weeks and stay small enough for a tent corner. Low-stress training suits them better than heavy topping.
Auto Chemdog for speed, Girl Scout Cookies for the top of the THC range at 24%. Candy Kush and Dreamberry cover the sweeter end; only Auto Pounder and Dreamberry ask for Moderate experience.
THC here runs 18% to 24%, a normal autoflower band but well under the 30-plus shelves elsewhere in the seedshop, so pick this brand for a reliable easy grow rather than raw power. Seed to harvest is 8 to 12 weeks depending on strain, not the 8 to 10 often quoted. Want a wider choice than these nine? The full autoflowering cannabis seeds category collects every brand we carry.
The head office is in London, and the breeding work is carried out in Spain and the Netherlands. The brand has bred autoflowering seeds exclusively since 2008.
Girl Scout Cookies at 24% THC, followed by GG#4 Auto at 23%. The range tops out lower than modern photoperiod shelves, which reach past 30%.
Auto Chemdog, ready 8 to 9 weeks from seed. Auto Pounder and Hijack sit at the other end at 11 to 12 weeks.
Seven of the nine are rated easy to grow, and no strain needs a light-cycle switch. Only Auto Pounder and Dreamberry ask for moderate experience.
No. The catalogue is autoflower only. For photoperiod options browse the wider cannabis seeds range.
