El Alquimista Feminized Cannabis Seeds by Samsara Seeds
El Alquimista is a feminized cannabis seed from Samsara Seeds that crosses two legendary strains — Northern Lights and AK 47 — into a 70% Indica / 30% Sativa hybrid with 21% THC. It's the kind of cross that sounds like it was designed in a lab, but grows like a weed in a ditch. Practically zero fuss, massive yields, and a flowering time that won't test your patience.
Why El Alquimista Cannabis Seeds Deserve a Spot in Your Grow
Every grower who's run El Alquimista says the same thing: it practically grows itself. That's not marketing fluff — the Afghan genetics inherited from Northern Lights give this plant genuine resistance to mould and disease, which means you're not babysitting it through every humidity spike or temperature swing. The AK 47 side contributes rapid-flowering Sativa genetics that keep the total bloom time to a brisk 7 to 9 weeks. For an Indica-dominant plant pushing 21% THC, that's a quick turnaround.
If you're running your first indoor grow and you want something forgiving, this is where we'd point you. And if you're a seasoned grower who just wants reliable, heavy-yielding plants that don't demand constant attention — same recommendation, different reason. We've seen first-timers pull respectable harvests from El Alquimista because the genetics do most of the heavy lifting.
The one honest limitation: this isn't a high-CBD strain. At 21% THC with no notable CBD content listed, it's bred purely for potency. If you're after a balanced cannabinoid profile, look at something like a 1:1 CBD/THC variety instead. But if THC is what you're growing for, El Alquimista delivers it without making you work for it.
El Alquimista Yield and Growing Specifications
The numbers on this strain are genuinely impressive for a plant this easy to manage. Here's what you're working with:
| Specification | Detail |
|---|---|
| Seed Bank | Samsara Seeds |
| Genetics | Northern Lights x AK 47 |
| Type | Feminized (photoperiod) |
| Indica / Sativa | 70% Indica / 30% Sativa |
| THC Content | 21% |
| Flowering Time | 7-9 weeks |
| Indoor Yield | Up to 450 g/m² |
| Outdoor Yield | Up to 700 g per plant |
| Mould Resistance | High (Afghan genetics) |
| Seeds per Pack | 3 |
Up to 700 grams per plant outdoors is a serious number. Indoors, 450 g/m² puts El Alquimista comfortably in the high-yield category. Compare that to a standard Northern Lights feminized, which typically tops out around 500-550 g outdoors — El Alquimista's AK 47 parentage clearly pushes the production ceiling higher.
Northern Lights x AK 47: What the Genetics Actually Mean
Strain crosses get thrown around so casually that the parent names start to feel like decoration. With El Alquimista, both parents are doing real, measurable work.
Northern Lights is one of the most stable Indica genetics on the planet. It's been a backbone of breeding programmes since the 1980s, and the reason is simple: it's compact, it resists mould, and it finishes fast. The Afghan landrace genetics behind Northern Lights give El Alquimista its disease resistance and its dense, resinous bud structure. When you crack open a dried El Alquimista flower, that thick coating of trichomes — the sticky, crystalline layer on the surface — is the Northern Lights showing through.
AK 47, despite the aggressive name, is a multiple Cannabis Cup winner known for its vigorous growth and surprisingly quick flowering for a Sativa-influenced hybrid. It's the AK 47 genetics that keep El Alquimista's flowering window at 7-9 weeks rather than the 10-12 you'd expect from many Indica-dominant strains at this potency level. The Sativa influence also adds some vertical stretch, so expect plants that are slightly taller and more open than a pure Indica — good news for light penetration in an indoor setup.
How to Grow El Alquimista Feminized Seeds
- Germination: Use the paper towel method or soak seeds in room-temperature water for 12-24 hours until taproots emerge. Feminized seeds mean every plant that germinates will flower as female — no need to sex and cull males.
- Seedling stage: Transplant into small pots with light, airy soil. Keep humidity around 65-70% and temperatures between 20-25°C. El Alquimista seedlings are robust, but don't drown them — overwatering is still the number one killer at this stage.
- Vegetative growth: Under 18/6 lighting, let plants develop for 4-6 weeks indoors. The Indica dominance means they'll stay relatively compact, but the AK 47 genetics add some stretch. Top or LST (low-stress training) if you want to maximise that 450 g/m² potential.
- Flip to flower: Switch to 12/12 lighting. El Alquimista flowers in 7-9 weeks — start checking trichomes with a loupe from week 7. You're looking for mostly cloudy trichomes with a few turning amber.
- Outdoor growing: Plant out after the last frost. The mould resistance from the Northern Lights genetics means this strain handles damp autumn conditions better than most. Expect harvest in early to mid-October in northern European climates.
- Drying and curing: Hang branches in a dark room at 18-20°C with 55-60% humidity for 7-10 days. Cure in glass jars for at least 2 weeks — the terpene profile develops noticeably with a proper cure.
El Alquimista Compared to Similar Strains
If you're deciding between El Alquimista and other heavy Indica hybrids, here's how the numbers stack up:
| Strain | Genetics | THC | Flowering | Indoor Yield | Outdoor Yield |
|---|---|---|---|---|---|
| El Alquimista (Samsara) | Northern Lights x AK 47 | 21% | 7-9 weeks | 450 g/m² | 700 g/plant |
| Northern Lights (standard) | Afghan landrace | 16-18% | 7-8 weeks | 400 g/m² | 550 g/plant |
| AK 47 (standard) | Colombian/Mexican/Thai/Afghan | 17-20% | 8-9 weeks | 400 g/m² | 500 g/plant |
El Alquimista beats both parents on yield and matches or exceeds them on THC. The 21% THC figure puts it 3-5 percentage points above a typical Northern Lights, and the outdoor yield of 700 g per plant is roughly 27% more than a standard AK 47. If you want the best traits of both parents without the compromises, this is the cross that delivers.
Growing El Alquimista indoors? Pair these seeds with a complete grow tent kit for a hassle-free setup. A carbon filter and extraction fan will handle the earthy flowering aroma, and a digital pH meter keeps your nutrient solution dialled in — especially useful during the 7-9 week bloom phase when feeding precision matters most.
THC Content and Cannabinoid Research
At 21% THC, El Alquimista sits in the upper range of commercially available cannabis genetics. THC — delta-9-tetrahydrocannabinol — is the primary psychoactive cannabinoid in cannabis. According to a review published in the Annals of Internal Medicine, "cannabinoid delta-9-tetrahydrocannabinol has been determined to have the primary psychoactive effects; the effects of several other key cannabinoid compounds have also been identified" (PubMed 23386598).
Research into the broader therapeutic potential of cannabis continues to develop. According to a review in Frontiers in Psychiatry, clinical studies involving cannabinoid administration "provide some of the strongest evidence as to the therapeutic potential" of cannabis in certain contexts (PMC 9648847). It's worth noting that El Alquimista is a THC-dominant strain with no significant CBD content, so the cannabinoid profile is straightforward rather than broad-spectrum.

Frequently Asked Questions
Is El Alquimista a good strain for first-time growers?
Yes — it's one of the most forgiving feminized strains we carry. The Northern Lights genetics give it strong mould and disease resistance, and the plant doesn't need constant attention. Expect it to grow well with basic equipment and minimal intervention.
How long does El Alquimista take to flower?
Between 7 and 9 weeks from the switch to 12/12 lighting. The AK 47 parentage keeps the flowering period shorter than you'd expect for a 70% Indica at this potency. Start checking trichome colour from week 7.
What yield can I expect from El Alquimista indoors?
Approximately 450 grams per square metre under standard indoor conditions. Outdoors, yields can reach up to 700 grams per plant. These figures assume healthy plants with adequate light, nutrients, and ventilation.
Is El Alquimista resistant to mould?
Yes. The Afghan genetics from the Northern Lights parent give El Alquimista strong natural resistance to mould and common plant diseases. It handles damp conditions better than most strains, making it a solid choice for outdoor growing in northern European climates.
What does El Alquimista smell like during flowering?
Expect a dense, earthy aroma with spicy undertones during bloom. It's not the most pungent strain in the tent, but a carbon filter is still recommended. Dried flower has a slightly sweet, hashy quality that reflects the heavy resin production.
How does El Alquimista compare to regular Northern Lights seeds?
El Alquimista pushes THC to 21% versus Northern Lights' typical 16-18%, and outdoor yields reach 700 g/plant compared to roughly 550 g. The AK 47 genetics add vigour and slightly faster flowering. It's essentially Northern Lights with the volume turned up.
Can I grow El Alquimista outdoors in a cooler climate?
Absolutely. The Afghan-descended genetics handle temperature swings and damp autumn weather well. In northern Europe, expect to harvest in early to mid-October. The mould resistance is a real advantage when late-season rains arrive.
