Santa Marta Haze Feminized Seeds by Seed Stockers – High-THC Sativa for Massive Yields

Santa Marta Haze feminized seeds by Seed Stockers deliver one of the most potent, true-to-form sativa experiences available, combining soaring THC levels (23–26%) with massive yields and a refreshing citrus-pine aroma that electrifies the senses.

Still rolling mediocre highs and scrawny harvests? You know the drill — weeks of care, only to end up with bland buds and a buzz that fizzles by midday. It’s frustrating when your grow doesn’t match the legendary Haze promise of creativity, energy, and depth.

That lackluster finish isn’t just disappointing — it wastes your time, your space, and your hard-earned herb. You’re not just missing out on flavor; you’re missing the full psychedelic journey that only a genuine Haze can deliver. Settling for less means settling for a half-baked experience.

Enter Santa Marta Haze: a no-compromise sativa bred from Amnesia Haze and a wild Colombian jungle landrace. This isn’t just another photoperiod strain — it’s a flavor powerhouse and yield monster that delivers a long, euphoric, mind-expanding high. With dense, resin-coated buds and a flowering time of just 10 weeks, it turns your grow into a tropical harvest of pure, potent satisfaction.

Personal Experience of Pevgrow’s CEO (Alan)

Let me tell you — Santa Marta Haze is the real deal. I grew it last summer in my outdoor plot in southern Spain, and it went wild in the heat. Towered over 3.5 meters, covered in frosty trichomes. The high? Absolutely cerebral — I was painting, writing, just buzzing with ideas for hours. It’s not a couch-lock strain; it’s a creativity engine. I ran a SCROG net to manage the height, and yields were insane — over 1.2 kg per plant. Smell was intense, so I used a Barrier filter indoors during drying. If you want a true Haze experience, this is it. Don’t prune it too hard — let it stretch. And flush it well — the flavor payoff is worth it.
