2046 Cannabis Seeds by Medical Seeds
2046 is a 100% pure sativa cannabis seed strain from Medical Seeds that delivers a powerful, psychedelic-grade experience backed by THC levels reaching up to 25%. Built on a Haze genetic foundation, this is a grower's challenge and a connoisseur's reward — 120 days of flowering patience for a harvest that hits like nothing else on your shelf. This guide is written for adults aged 18 and over.
Why 2046 Sativa Seeds Stand Apart
Most seed banks pad their catalogue with easy-growing hybrids. 2046 goes the opposite direction — this is an uncut, undiluted Haze sativa that hasn't been crossed down for convenience. The result is a plant that grows tall, flowers long, and produces a finished product with a sharp, resinous Haze aroma that you can smell through the bag. Think incense, spice, and that slightly metallic tang you get from properly cured sativa flower.
We'd pick 2046 over a generic Haze cross if you've already got a few grows under your belt and want something genuinely different. If you're after a quicker, more forgiving sativa experience, Medical Seeds' 1024 strain finishes faster and still carries solid Haze genetics — but it won't match the sheer intensity of 2046. That's the trade-off: patience for potency.
The honest limitation? This strain is not for first-time growers. A 120-day flowering period means four months of managing a tall, stretchy plant that will test your space, your patience, and your light schedule. Outdoors, she won't finish until late November, which rules out most of Northern Europe unless you've got a greenhouse. Indoors, you'll need vertical space — she stretches hard in the first weeks of flower.
Growing 2046 Feminised Seeds
2046 demands skill and rewards it generously. Indoor growers can expect up to 500 g/m2 under optimal conditions, which is impressive for a pure sativa with this flowering time. Here's what you need to know before popping the seed.
| Specification | Detail |
|---|---|
| Seed Bank | Medical Seeds |
| Genetics | 100% Sativa (Haze-based) |
| THC Content | Up to 25% |
| Seeds per Pack | 3 |
| Seed Type | Feminised |
| Indoor Flowering Time | 120 days |
| Indoor Yield | Up to 500 g/m2 |
| Outdoor Harvest | Late November |
| Difficulty | Expert |
| Aroma | Haze, spice, incense |
- Germinate your 2046 seeds using the damp paper towel method — place seeds between two moist sheets on a plate, cover, and keep at 22-25°C. Taproots typically emerge within 48-72 hours.
- Transplant into a small pot (0.5L) with light, airy soil. Pure sativas hate waterlogged roots, so mix in 20-30% perlite for drainage.
- Keep the vegetative phase short — 2 to 3 weeks maximum. 2046 will double or triple in height during the flowering stretch, so a plant that's 30cm at flip can easily reach 90-120cm by harvest.
- Switch to 12/12 light cycle and prepare for the long haul. The 120-day flowering period is not an exaggeration. Do not harvest early — the final 2-3 weeks are where the resin production and terpene complexity really develop.
- Train aggressively. LST (low-stress training) and SCRoG nets are your best friends here. Without training, 2046 will grow straight up and shade out lower branches.
- Monitor humidity carefully during the final weeks. Dense Haze buds and long flowering times create mould risk if relative humidity climbs above 50%.
- For outdoor growers: 2046 finishes in late November. This means Mediterranean climates, greenhouses, or supplemental lighting setups only. If your autumn brings frost before December, grow indoors.
2046 Sativa: Aroma, Flavour, and Effects
The aroma profile is classic old-school Haze — sharp, incense-heavy, with woody and earthy undertones. Crack a cured bud and you'll get that unmistakable Haze funk that fills a room. The flavour follows through: spicy on the inhale, woody and slightly sweet on the exhale, with a lingering aftertaste that sits at the back of your throat.
At up to 25% THC with pure sativa genetics, the effects lean heavily cerebral. Experienced users describe a strong, uplifting, and intensely clear-headed experience. This is a daytime strain through and through — the kind that sparks creative energy rather than couch-lock. The onset tends to be quick and builds steadily over the first 15-20 minutes.
Research into cannabis sativa strains continues to expand. According to a review in Cannabis, a Miracle Drug with Polyvalent Therapeutics, clinical studies have observed that medical cannabis may have beneficial effects on patients with fibromyalgia (2018) (PMC8525216). And according to Cannabis sativa: Interdisciplinary Strategies and Considerations, the treatment of conditions such as epilepsy and chronic pain remain active research targets for cannabinoid science (PMC7996784). It's worth noting that research also shows cannabis use is associated with varied neurocognitive outcomes, as reported in a meta-analysis on adverse effects (PMC6925658). The science is still catching up — we don't make claims, we just follow the papers.
Running a 120-day flowering cycle? You'll want reliable environmental control. A complete grow tent kit with carbon filter and extraction fan keeps humidity and odour managed across that long stretch. Pair your 2046 seeds with a quality pH meter and CalMag supplement — pure sativas are notoriously sensitive to pH drift and calcium deficiency during extended flower.
2046 vs Other Medical Seeds Sativa Strains
Medical Seeds offers several sativa-leaning genetics. Here's how 2046 compares to its closest siblings in the catalogue.
| Strain | Genetics | Flowering Time | THC | Difficulty |
|---|---|---|---|---|
| 2046 | 100% Sativa (Haze) | 120 days | Up to 25% | Expert |
| 1024 | Sativa-dominant Haze hybrid | 70-80 days | Up to 22% | Intermediate |
| Malakoff | Sativa-dominant | 65-75 days | Up to 20% | Intermediate |
If 2046 is the deep end, 1024 is the pool where you learn to swim. Both carry Haze genetics, but 1024 finishes in roughly half the time and forgives more mistakes. Malakoff is even more accessible. We'd say: grow 1024 first, then graduate to 2046 once you've got your environment dialled in.
Frequently Asked Questions
How long does 2046 take to flower?
2046 has a flowering period of approximately 120 days — that's four full months from the switch to 12/12. This is standard for a pure Haze sativa. Cutting the cycle short will significantly reduce potency and terpene development.
Is 2046 indica or sativa?
2046 is 100% sativa, bred from pure Haze genetics by Medical Seeds. There's no indica in this lineage at all, which accounts for both the long flowering time and the intensely cerebral effects.
What yield can I expect from 2046 indoors?
Under optimal conditions with proper training (SCRoG recommended), 2046 can produce up to 500 g/m2 indoors. Achieving this requires the full 120-day flowering period, good light penetration, and careful humidity management.
Can I grow 2046 outdoors in Northern Europe?
Not recommended without a greenhouse. 2046 harvests in late November, which means your plants will face cold temperatures, rain, and high mould risk in most Northern European climates. Mediterranean or subtropical climates are far better suited.
Is 2046 suitable for beginner growers?
No. The 120-day flowering time, extreme vertical stretch, and sensitivity to environmental conditions make 2046 an expert-level strain. If you're newer to growing, start with Medical Seeds' 1024 — it carries similar Haze genetics but finishes much faster and tolerates more mistakes.
What does 2046 smell and taste like?
Classic old-school Haze: sharp incense, spice, and woody undertones. The flavour carries through on the exhale with a slightly sweet, lingering finish. Expect the aroma to fill a room — a carbon filter is not optional with this strain.
How many seeds come in a pack of 2046?
Each pack contains 3 feminised seeds. Given the expert-level difficulty and long growing cycle, the 3-seed format lets you run a focused grow without overcommitting resources.
