Jack 47® by Sweet Seeds – Potent Sativa Hybrid with Citrus & Incense Aroma

Jack 47® by Sweet Seeds is a powerhouse sativa hybrid that delivers big flavor, massive resin, and a long-lasting cerebral kick — all wrapped in one of the most balanced grower-friendly plants out there.

Still stuck in the same old strain routine, only using one type of plant for every moment?

Most growers stick to just one kind of experience — either too lazy to switch, or stuck with a strain that doesn’t adapt. That means missing out on flavor, wasting space, and settling for mediocre effects when you could be thriving.

Meet Jack 47®: the hybrid that masters every scenario. Whether you’re chilling solo, creating art, or sharing vibes with friends, this strain shifts perfectly between roles. It grows like a beast, tastes like a dream, and hits just right — no matter the time or place.

At Home: Your Creative Daytime Companion

When you're flying solo at home, Jack 47® is your ultimate muse. Its sativa-driven high sparks focus, creativity, and a joyful energy that makes chores feel fun and projects flow effortlessly. The plant’s open structure and long lateral branches make it a breeze to train indoors — perfect for SCROG or topping setups.

With a flowering time of just 9½ weeks, you’ll be harvesting dense, resin-coated buds that fill the room with sweet citrus, fresh incense, and a hint of orange. Break open a nug, and the mango undertone hits — smooth, rich, and unforgettable.

Pro tip: Pair it with a light sativa-friendly nutrient like Jungle Juice Grow Advanced Nutrients to maximize terpene expression without overfeeding.

Outdoors: Big Plants, Bigger Harvests

Under the sun, Jack 47® transforms into a towering giant — reaching up to 1.60 m (5.25 ft) with massive colas that soak up sunlight. It thrives in Mediterranean or temperate climates and shows strong resistance to pests, mold, and temperature swings.

Thanks to its genetic vigor, it adapts to soil, coco, or hydro setups and produces maximum yields when given quality nutrition and good drainage. Outdoor harvests are nothing short of spectacular, with plants delivering rock-hard, frosty buds that are perfect for extractions or long-term storage.

Support those heavy branches early — a little JoJo or netting goes a long way. And if you're growing in a high-humidity area, keep airflow strong to avoid any moisture buildup.

How to Choose Your Ideal Growing Style

Jack 47® fits every grower — but your approach depends on your vibe and space.

• If you're a minimalist with limited space, go for a shorter veg (3–4 weeks) and let it flower fast.

• If you're into cloning, this is your dream plant — roots appear in just 7 days, and cuttings stay true to form.
• If you love flavor and aroma, go slow: cure for 4 weeks and let those citrus-woody notes deepen.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of sativas, but Jack 47® stands out as one of the most reliable and rewarding. I first tried it in a 15 L pot under 600W HPS, with a 5-week veg and SCROG setup. The stretch was impressive — nearly doubled in height — but the structure held strong.

The aroma during flowering was unreal: sweet lemon and incense filled the grow room. I topped three times to maximize yield, and each cola came in thick and frosty. After a 10-day flush and 4-week cure, the smoke was smooth, uplifting, and deeply creative — perfect for writing or long walks.

What I love most is its versatility. I’ve also grown it outdoors in Valencia, where it hit 1.5 m (4.92 ft) and produced monster colas. For beginners, I’d recommend a simpler setup — but for those ready to push limits, this strain delivers championship-level results.
