Sinai by Anesia Seeds

Sinai Strain Info

Some strains are all about power, others about flavor, and then there’s Sinai—a landrace legend straight from the heart of the rugged Sinai Peninsula.

It’s not just another hybrid pumped out by modern breeding; it’s a pure, untouched lineage that’s been thriving in the wild for centuries.

This strain has history woven into its DNA, cultivated by Bedouin tribes in one of the world’s toughest climates, making it a true survivor.

Unlike today’s commercial crosses, Sinai remains 100% sativa, delivering a cannabis experience as nature intended.

Flowering Time & Yield

Patience pays off, and with 10 to 12 weeks of flowering, Sinai rewards growers with serious yields.

Indoors, expect up to 550g/m² (19.4 oz/ft²) of long, resinous colas, bursting with pure sativa energy.

Outdoors, where this strain feels most at home, it transforms into a towering beast, reaching up to 3 meters (9.8 ft) in height.

With the right conditions, harvests can exceed 1,000g (35 oz) per plant, proving why this landrace has been cherished for generations.

As the season cools, Sinai shows off its wild side—sometimes developing deep purple hues, making it as stunning as it is productive.

Effects and Aroma

Sinai is a time machine, taking you back to an era when cannabis was pure, unrefined, and deeply spiritual.

Its high kicks off with a clear-headed rush, flooding the mind with energy, creativity, and a sharpened sense of awareness.

Perfect for deep conversations, artistic pursuits, or those moments when inspiration strikes like a lightning bolt.

As the ride continues, a smooth wave of physical relaxation settles in, easing tension without locking you to the couch.

No sudden crashes, no overwhelming sedation—just a balanced, natural high that lets you stay functional and in control.

The aroma tells its own story, a bold mix of earthy spices, incense, and wildflowers, reminiscent of the arid desert where it thrives.

On the inhale, peppery notes tingle the senses, followed by a rich, hashy undertone that lingers beautifully on the exhale.

If modern hybrids feel too artificial, Sinai brings you back to the roots—raw, authentic, and deeply satisfying.

With 21% THC powering this legendary strain, every hit delivers the perfect mix of clarity and tranquility.

If you’re searching for feminized cannabis seeds that offer resilience, high yields, and a pure, untamed experience, Sinai deserves a place in your grow.

Growing Tips & Our Take

Sinai is a landrace built for survival, which means it thrives where other strains struggle.

Extreme heat, drought, and pests? No problem—this strain has been toughened by centuries of harsh desert conditions.

That resilience makes it a solid choice for outdoor growers in warm, arid climates, but it also adapts well to indoor setups.

Its natural resistance to mold, mildew, and common pests makes it a forgiving option for those who want a low-maintenance grow.

That being said, this is a pure sativa, so expect some stretch—indoor growers should use SCROG or LST to keep height in check.

Outdoors, it’s a beast, easily reaching 3 meters (9.8 ft), so give it space and let it breathe.

Light defoliation can help improve airflow, especially in humid environments, ensuring those long colas get all the light they need.

Sinai isn’t a high-maintenance strain, but it does require patience—10 to 12 weeks of flowering is longer than most hybrids, but the reward is well worth it.

What stands out the most? For us, it’s the sheer authenticity—this isn’t some lab-designed hybrid, it’s a direct link to cannabis history.

Growing Sinai feels like stepping back in time, cultivating a piece of the past with all the modern benefits of feminized genetics.

Sinai Strain FAQ

Is Sinai sativa or indica?

Sinai is a pure sativa landrace, meaning it hasn’t been altered or crossbred with other strains.

Sativa strains are known for their tall structure, thin leaves, and energizing effects, making them ideal for daytime use and creative activities.

Indicas, on the other hand, tend to be shorter, bushier, and more relaxing, often associated with deep body highs and couch-lock effects.

Sinai delivers the classic sativa experience—uplifting, cerebral, and mentally stimulating—without the heavy sedation of an indica.

How long does Sinai take to flower?

Sinai has a flowering time of 10 to 12 weeks, which is slightly longer than most modern hybrids.

As a landrace sativa, it takes its time to develop its full potential, but the reward is dense, resin-coated colas packed with potency.

For outdoor growers, harvest usually falls between late October and early November, depending on local conditions.

Does Sinai grow well indoors?

Yes, but it requires some height management techniques due to its natural tendency to stretch.

Growers can use SCROG (Screen of Green) or LST (Low Stress Training) to keep it under control and maximize yields.

With the right setup, it thrives indoors, producing up to 550g/m² (19.4 oz/ft²).

Is Sinai resistant to pests and mold?

Absolutely—its origins in the harsh, arid regions of the Sinai Peninsula have made it highly resistant to drought, pests, and mold.

It’s an excellent choice for outdoor growers who want a resilient strain that can handle less-than-perfect conditions.

What climate is best for growing Sinai?

Sinai thrives in warm, dry, Mediterranean, and desert-like climates, where it can stretch to its full potential.

However, it also adapts well to controlled indoor environments, especially with proper light exposure and airflow.

Does Sinai turn purple?

Sometimes! If temperatures drop towards the end of the flowering cycle, some plants may develop deep purple hues, making them visually stunning.

This is a natural trait seen in some landrace strains when exposed to cooler conditions.
