Ramses Feminized Seeds by Pyramid Seeds – High-THC Sativa Hybrid for Powerful Cerebral Effects

Ramses feminized seeds by Pyramid Seeds deliver a high-THC sativa experience with intense cerebral effects, exceptional resin production, and a citrus-Haze flavor profile that defines premium genetics.

Still stuck with weak strains that barely lift your mood? You know the frustration: weeks of care for mediocre yields, bland flavors, and effects that fizzle out fast. It’s exhausting to invest time and energy only to end up with underwhelming results.

That plateau is real — when you’re using outdated genetics that don’t push boundaries. You’re not growing wrong; you’re just growing with seeds that can’t deliver the intensity and clarity you’re chasing. The gap between average and exceptional is wider than ever.

Ramses changes everything. This sativa-dominant powerhouse (80% sativa) is the result of crossing legendary Amnesia Haze with a rare private reserve strain, engineered for those who demand more: more potency, more flavor, more mental elevation. With THC levels hitting 23–26%, dense frosty buds, and a flowering time of just 80 days indoors, it’s built to outperform.

Typical mistakes this product helps you avoid

Even great strains can go wrong. Ramses’ robust genetics help you sidestep common pitfalls — if you respect its needs.

• Underestimating stretch: Its intense growth means early height control is crucial — use LST to manage space.
• Overcrowding: Long branches need room — keep proper spacing to ensure airflow and light penetration.
• Ignoring smell control: Medium-high odor means a carbon filter like HESI Root Complex can help maintain discretion.
• Harvesting too early: Wait for milky-to-amber trichomes — patience unlocks full cerebral power.
• Overfeeding: High vigour doesn’t mean high nutrient demand — follow a balanced feeding schedule with HESI Hydro Growth for steady development.

Frequently Asked Questions

What makes Ramses different from regular Amnesia Haze?

Ramses is a stabilized, exclusive phenotype with enhanced resin production, higher THC (23–26%), and improved yield potential while preserving the classic Haze cerebral effect and citrus aroma.

Can I grow Ramses outdoors in a colder climate?

Yes, but with caution. It thrives in Mediterranean or temperate climates. If you’re in a cooler zone, start early and ensure it finishes before heavy rains — its sativa structure is less mold-resistant.

How tall does Ramses get indoors?

Up to 1.10 m (3.61 ft). Due to its intense stretch, use LST or low-stress training early to control height and maximize light exposure.

Is Ramses suitable for SCROG or SOG setups?

Absolutely. Its long branches respond well to SCROG, while its high yield makes it effective in SOG with fewer plants. Just ensure proper spacing and airflow.

Does Ramses have any medical benefits?

Ramses provides a strong cerebral effect that many users find helpful for focus, creativity, and mood elevation. However, we make no medical claims — consult a professional for therapeutic use.

Personal Experience of Pevgrow’s CEO (Alan)

I first grew Ramses two seasons ago, and it immediately stood out. I’d been rotating classic sativas, but this one hit different — literally. The high is clean, expansive, and lasts for hours without the crash. I use it for morning creativity sessions, and it never overstimulates.

What surprised me was the resin. I’ve grown Amnesia lines for years, but Ramses looked like it had been dipped in sugar. I ran a SCROG setup with 9 plants in 20L pots, and each yielded over 750 g under 720W LEDs. The smell during flowering was intense — citrus and pine with that unmistakable Haze sharpness — so I definitely recommend a carbon filter.

For beginners, I’d say: don’t be intimidated. It’s medium difficulty, but the feedback is clear. If you see stretch, act early. For experts, it’s a canvas — train it right, and it’ll reward you with some of the most potent, aromatic buds you’ve ever grown. I keep coming back to it, not just for the yield, but for the experience.
