For guerrilla cannabis cultivation, we need to grow plants that can withstand the entire summer. That’s why we showcase the best seeds for guerrilla growing. Our plants will spend days alone under full sun, with little water, cold nights, and heavy summer rains in the mountains. For this reason, we must choose strains that can endure all of this and still provide us with successful harvests.
We must choose between feminized seeds or autoflowering seeds. Feminized cannabis seeds are varieties that should be planted in spring and harvested at the end of summer. Meanwhile, autoflowering cannabis seeds are much faster; they complete their cycle in 2 to 3 months, depending on the strain.
If you still haven’t decided which are the best cannabis seeds for guerrilla growing, we’ve selected the top feminized strains and the best autoflowering ones for you.
Best Feminized Cannabis Seeds for Guerrilla Growing
Feminized seeds are grown from March–April through September–October. Depending on when we germinate our feminized seeds, they will have more or less time to grow. Sometimes we may not want plants that grow too large, since they can be spotted more easily and will require much more care and nutrients.
In addition, we should choose plants with genetics that are resistant to diseases and pests. The following seeds we present have those characteristics and also feature short flowering cycles.
Critical + 2.0

Critical + 2.0 by Silent Seeds is one of the best strains for guerrilla growing. It is one of the most well-known plants commercially, thanks to its high yields, fast growth, and strong resistance to diseases and mold.
This plant can produce up to 1300 g/plant and will be ready to harvest by the end of September, just before the autumn rains arrive.
Early Skunk

Early Skunk by the renowned seed bank Sensi Seeds can be considered their best all-terrain outdoor strain. It grows very easily, quickly, and produces extremely abundant harvests, with some plants capable of reaching enormous sizes.
Its dense, resilient buds will be ready for harvest between late September and early October, offering a powerful yield of up to 1500 g/plant.
Frisian Duck

Frisian Duck by Dutch Passion is a plant that adapts exceptionally well to guerrilla growing, which is why it is considered one of the best strains for this purpose. It is difficult to identify, since it doesn’t have the distinctive cannabis leaf shape, allowing it to blend in easily with surrounding vegetation. It can only be recognized as a cannabis plant once the buds are ready for harvest.
This strain is easy to grow and highly resilient, with strong stems and massive yields. Production will not drop below 400 g/plant, and it can reach up to 3 meters in height. Harvest time is early October.
Green Poison Fast Version

Green Poison Fast Version by Sweet Seeds is a strain with an ultra-fast flowering phase. But it’s not just its speed that makes it one of the best seeds for guerrilla growing — it’s also highly resistant to mold. Thanks to its strong resistance and rapid flowering, it can be harvested before the autumn rains arrive, effectively avoiding botrytis.
This plant can yield up to 700 g/plant of resin-packed buds, and will be ready to harvest in early September.
Northern Lights

Northern Lights by Sensi Seeds is a true cannabis classic. Its Afghan and Thai genetics make it a compact, vigorous plant, and one of the best strains for guerrilla growing.
It is easy to cultivate, highly resistant to cold, and under optimal conditions can produce yields of up to 600 g/plant. Northern Lights will be ready to harvest in early October, just before the cold and rains set in.
White Widow

White Widow by Green House Seeds is a legendary strain known worldwide. It has a compact, indica-like appearance, highly resistant, with long branches.
This plant will be ready for harvest by late September and can yield up to 900 g/plant. Its resin-covered buds will withstand the summer heat and chilly nights beautifully, delivering that unmistakable flavor of this world-famous strain.
These are some of the best feminized cannabis seeds for guerrilla growing from our catalog. Choose the variety that best suits you, your location, and your grow. And if feminized strains don’t quite convince you, we also recommend our selection of autoflowering seeds.
Best Autoflowering Cannabis Seeds for Guerrilla Growing
Guerrilla growing with autoflowering plants can make things much easier. Autoflowering seeds have a much faster life cycle than feminized ones, which means we can achieve results sooner and with less work — although it’s worth noting that the yields will be smaller compared to feminized strains.
Autoflowering plants are quick, easy to camouflage, and while their production is lower, these varieties certainly won’t leave anyone disappointed.
+ Speed Auto

+ Speed is one of the fastest autoflowering seeds to grow. This strain will be ready to harvest in just 7 weeks. In addition to its rapid cycle, it is also a resilient plant, thanks to its Critical genetics.
It can reach up to 90 cm in height, producing yields of up to 150 g/plant, making it a discreet and easy-to-camouflage option. For all these reasons, it is considered one of the best seeds for guerrilla growing.
Afghan Auto

Afghan Auto by Positronics Seeds is a highly recommended strain for outdoor cultivation. It is a robust, resilient plant with an impressive size — so much so that you might even doubt it’s autoflowering.
Its full cycle takes only 70–80 days, producing at least 200 g/plant. The flavor is none other than the classic Afghan profile: spicy, earthy, with a slight citrus finish.
Auto Mazar

Auto Mazar by Dutch Passion is a strain that is extremely easy to grow. It’s perfect for beginners in cannabis cultivation, which makes it highly recommended for guerrilla growing.
Its resilient genetics and ease of cultivation make it one of the best seeds for this purpose. Despite being an older strain, it still impresses today with all of its qualities. In about 70–80 days, Auto Mazar will be ready to deliver at least 100 g/plant.
While it doesn’t thrive under constant rain, it can tolerate some humidity without suffering from fungal diseases or mold damage.
Northern Lights Auto

Northern Light Auto by Royal Queen Seeds is the perfect combination of old and new. Not only is it one of the most productive autoflowering varieties, yielding up to 200 g/plant, but it also completes its cycle in just 70–77 days.
A fast yet productive plant, it delivers spectacular results and can withstand the entire growing season, making it one of our top guerrilla seeds.
It’s the same classic Northern Lights as always — but this time in autoflowering form.
Quick One

Quick One by Royal Queen Seeds is a very discreet plant, yet it can reach up to one meter in height. This makes it perfect for guerrilla growing and earns it a place among the best seeds for this purpose.
It’s not only its discretion that makes it ideal — with just 9 weeks of cultivation and yields of up to 150 g/plant, it’s a highly recommended variety. While its THC content is only around 13%, its effect is subtle yet very pleasant.
Sweet Skunk Auto

Sweet Skunk Auto by Sweet Seeds joins our selection of the best seeds for guerrilla growing. The cross between Early Skunk and Critical has produced a strain that is resilient, productive, and very fast.
In just 70–75 days, its buds will be mature and ready to harvest, with yields of up to 150 g/plant. This compact and discreet plant is ideal for growing in places where you don’t want it to be easily spotted.
