Why you should buy Black Jack seeds

Black Jack isn’t just another cool-sounding hybrid. It’s the real deal. A proper 50/50 cross that hits like a sledgehammer wrapped in velvet. You’ve got Black Domina bringing the muscle, and Jack Herer coming in with that old-school, cerebral sativa sparkle. Together? It’s like getting hugged and hyped up at the same time.

This one delivers dense, frosty nugs that reek of earthy spice with a subtle floral twist. It’s smooth, strong, and surprisingly versatile. Whether you’re looking to unwind without switching off or just want something that makes you feel good without flattening you, Black Jack shows up and does the job.

And growers? They love this plant. It’s stable, vigorous, and doesn't need babysitting. Tie it down, top it, or just let it do its thing. It’ll perform either way.

Strain Overview

Origin

Black Jack is what happens when two legends hook up. On one side, Black Domina, the indica that drips with resin and finishes fast. On the other, Jack Herer, bright, euphoric, and straight-up iconic. The result is a hybrid that brings the best of both without leaning too hard in either direction. Balanced, punchy, and built to impress.

Effects & Flavors

Expect a head-to-toe experience here. The high kicks off with a clean, happy buzz. Good vibes, sharp focus, maybe even a little giggle. Then the body comes online with a soft, creeping calm that takes the edge off without gluing you to the sofa.

Flavor-wise? Think earthy base notes with a touch of floral sweetness and a spicy kick at the end. Nothing too loud or flashy. Just solid, classic, tasty smoke that feels like it belongs in a well-loved stash jar.

THC & CBD Levels

Black Jack clocks in around 21% THC, so it’s got plenty of bite without going overboard. The CBD’s low, but honestly, the high is so nicely rounded you won’t miss it. It’s strong enough to satisfy heavy hitters but smooth enough for a mid-week joint.

Terpenes

There’s a whole line-up working in here. Limonene keeps things bright and focused. Linalool and humulene dial in the chill. Beta-caryophyllene brings that peppery kick. You’ll also catch a bit of eucalyptus and pine in the background, giving it a fresh, clean finish that lingers in the nose.

Growing Black Jack Seeds

Grow Difficulty

Whether it’s your first grow or your fiftieth, Black Jack is a safe bet. It’s tough, responsive, and handles stress like a champ. It plays nice with training too. SCROG, LST, topping, you name it. This is the kind of strain that makes you feel like you know what you’re doing, even if you’re winging it.

Indoor vs. Outdoor Growing

Indoors, she’ll stretch a bit but nothing wild. Strong side branches, great structure, and she fills out nicely with a bit of encouragement. Expect plants to reach around 51 inch to 67 inch inside. Outdoors, she thrives in warm, dry climates and really puts on size when the conditions are right, reaching up to 106 inch tall but usually between 71 inch and 106 inch. If you’re growing in a greenhouse, she’ll happily take that too.

Flowering Time & Yield

Black Jack finishes in 8 to 9 weeks with thick, resin-coated colas and zero fluff. Yields indoors average around 1.3–1.6 oz per square feet, while outdoors she can produce anywhere from 17.6–24.7 oz per plant. It’s one of those strains that doesn’t make you wait too long and still brings plenty to the table.
