Best strains to grow outdoors in spain
Not sure what to run outside this season? This guide breaks Spain into Mediterranean, interior, and northern coastal zones, explains the key traits to look for (heat, humidity, and finish time), and suggests beginner-friendly photoperiod and auto genetics you can buy at Zamnesia.
Curious about the very best strains to grow outdoors in Spain for the best quality flowers and biggest yields? Then you’re in the right place. Spain’s climates vary a lot, from hot Mediterranean coasts to cooler, wetter northern stretches, so the smartest move is choosing genetics that actually match your local conditions.
Below, we’ll break things down by major growing regions and highlight reliable Zamnesia-available picks, including both autoflowers for speed and flexibility, and photoperiod strains for maximum outdoor potential.
Growing cannabis outdoors in Spain
Spain has huge outdoor growing potential, but results depend on matching your strain to the local climate. Along the Mediterranean coast, you’ll typically get long, warm summers with dry heat. In the continental interior, expect big day–night temperature swings and, in many spots, a shorter, less forgiving season. Up on the Atlantic/northern coast, summers are cooler with higher humidity and more rain.
In general, strong outdoor choices combine vigour, mould resistance, early-to-mid flowering, and solid stress tolerance.
What makes a strain suited for Spanish climates
The best outdoor strains for Spain can handle summer intensity, but also stay resilient when conditions turn. In hotter areas, heat tolerance helps plants keep pushing without stalling. In the north, resistance to humidity and rain is key to avoiding problems late in flower.
Look for a bud structure that’s open enough to let air move through, yet dense enough to deliver proper weight and quality. Finally, predictable finishes before autumn are crucial, especially where nights cool down fast.
Best outdoor strains for Mediterranean Spain
Mediterranean Spain is the warmest, driest outdoor region, with plenty of sun and a long season to play with. That extended flowering window makes it especially friendly for photoperiod strains that like to veg a little longer and grow into bigger plants.
In short: if you’ve got space and steady sunshine, this is the part of Spain where slightly larger genetics can really stretch out and reward you with serious harvests.
Royal Gorilla (Royal Queen Seeds) feminized
If you want one all-rounder for Mediterranean Spain, Royal Gorilla Feminized is a dependable shout. It’s nicely balanced for outdoor life, handling heat and the long season without getting fussy.
The payoff is potent flowers alongside reliably strong yields, ideal if you’re chasing quality but still want a harvest you can actually weigh.
Kalini Asia (Zamnesia Seeds) feminized
For growers chasing a more tropical vibe, Kalini Asia leans into warmth and light. It’s a vigorous outdoor performer with good heat tolerance, which is exactly what you want along the Mediterranean coast.
Give it room and steady sun, and it will take full advantage of long days, building momentum through the season.
Fastberry Auto (FastBuds) feminized
If you prefer autos, Fastberry Auto is a terrific all-rounder for Mediterranean gardens. It’s quick to finish, copes well with heat, and stays on track in drier conditions.
You’ll also get a strong fruity flavour profile, making it a great option when you want speed without sacrificing quality.
Strawberry Cough Auto (Zamnesia Seeds) feminized
Strawberry Cough Auto is a smart pick when you want an early finisher that loves consistent Mediterranean sun. Because it moves quickly through its cycle, you can often wrap up before late-season humidity spikes start creeping in.
That speed also makes it handy for tighter schedules, or for fitting in more than one outdoor run if your setup allows.
Best outdoor strains for continental/interior Spain
Interior Spain can be intense: hot days, cooler nights, and big temperature swings that test a plant’s resilience. On top of that, early autumn can bring a sudden hit of cold and rain, so finishing on time matters.
Look for genetics that handle stress well and don’t need forever to ripen—especially if you’re growing at altitude or in areas where September weather can turn quickly.
Amnesia Lemon (Barney’s Farm) feminized
A solid option for inland grows, Amnesia Lemon is a strong hybrid that doesn’t drag its heels, thanks to a medium flowering time.
It also takes the typical interior pattern in its stride—coping with daytime heat, then holding up when temperatures dip at night—making it a reliable choice where conditions can swing fast.
Hella Jelly (Humboldt Seed Company) feminized
-Feminized.jpg "Hella Jelly (Humboldt Seed Company)")
Hella Jelly Feminized brings balanced genetics with the kind of structure and vigour that outdoor growers appreciate in the interior. It’s the sort of plant that stays manageable while still pushing strong growth through the season.
That makes it a particularly good fit for places like Madrid and inland valleys, where you can get blazing sun in the day and noticeably cooler air once the evening rolls in.
Amnesia Haze Auto (FastBuds) feminized
For interior growers who want speed, Amnesia Haze Auto is a fast-finishing auto that doesn’t feel fragile. It has enough vigour to keep performing through the temperature swings you get inland, from scorching afternoons to cooler nights.
That quick turnaround can also help you stay ahead of early autumn cold snaps and rain.
Northern Lights Auto (Dutch Passion) feminized
A real old-school workhorse, Northern Lights Auto is a classic hardy autoflower for growers dealing with inland extremes. It’s notably tolerant of cooler night temperatures, so those post-sunset drops won’t knock it off course.
It also handles late-season stress well, making it a sensible choice if autumn weather threatens to turn before you’ve finished up.
Best outdoor strains for Atlantic/Northern Spain
Northern Spain’s Atlantic edge is a different game: cooler summers, plenty of rain, and consistently higher humidity. The big enemy here is mould, especially once flowers start to stack and air circulation drops.
Go for varieties that resist moisture-related issues and don’t need a long, late finish outdoors. In this climate, a strain that stays healthy through damp spells is worth more than one that’s simply big or fast.
Special Queen 1 (Royal Queen Seeds) feminized
Built on classic Skunk lineage, Special Queen 1 is a practical pick for the Atlantic coast. It’s known for strong resilience outdoors, which really matters when humidity and drizzle are part of the routine.
Just as importantly, it finishes early, helping you bring plants in before the wettest part of the season ramps up and mould risk climbs.
Tropicana Cookies (Zamnesia Seeds) feminized
If you’re growing up north and don’t want to gamble with damp weather, Tropicana Cookies Feminized is a solid option. It’s robust, packs plenty of flavour, and tends to develop a structure that’s friendly to airflow—handy when the forecast is more cloud than sun.
That open growth pattern, paired with good mould resistance, makes it a sensible choice for gardens where humidity can linger for days.
Jack Herer Auto (Greenhouse Seeds) feminized
-feminized.jpg "Jack Herer Auto (Greenhouse Seeds)")
For lighter Atlantic summers, Jack Herer Auto is a handy middle ground: a balanced hybrid auto that’s easier to manage than a long-flowering photoperiod.
It brings good mould resistance to the table, which is exactly what you want when humidity hangs around, and the early finish helps you dodge the worst of late-season rain. Ideal if you’d rather harvest clean than push your luck.
Blackberry Auto (FastBuds) feminized
-feminized.jpg "Blackberry Auto (FastBuds)")
Blackberry Auto is a compact, hardy autoflower that suits smaller outdoor spots and changeable northern weather. Its sturdy nature helps it cope when humidity is high, and the sun isn’t always guaranteed.
Because it runs quickly, you also get earlier harvest windows, useful on the Atlantic coast, where a timely finish can mean the difference between clean buds and battling rot in late-season rain.
Choosing the right strain for your region
To pick the right genetics, start by matching your exact location to Spain’s three main outdoor zones, then choose strains with traits that suit that weather pattern.
- Mediterranean coast & islands: hot, dry summers.
- Continental/interior: big temperature swings and shorter seasons.
- Atlantic/northern coast: cooler, wetter, higher humidity (mould pressure).
Practical tips for outdoor growing in Spain
Spain rewards growers who play to their region’s strengths. On the Mediterranean coast, you can often run photoperiod genetics later into the season, letting plants bulk up before the chop.
In the continental interior, timing is everything; start early so you’re not finishing as nights cool down in late autumn. Up on the Atlantic side, prioritise mould resistance and keep airflow high with sensible spacing and light pruning.
Grow smarter by matching genetics to your Spanish climate
Spain doesn’t have one “outdoor season”; it has three, and your best results come from choosing genetics that fit your local conditions. If you’re in a hot Mediterranean pocket, you can lean on longer-running photoperiods; in the interior, fast finishers help you beat the autumn drop; and along the Atlantic coast, mould resistance and airflow-friendly plants are the smart bet.
