Super Jack strain guide
Super Jack is a sativa that crosses Jack Herer with Super Silver Haze, two of the best-known daytime strains around. People know it for a sweet, spicy smell with a buttery edge and a clear, energetic feel. It also goes by Super Jack Herer and Super Silver Jack.
Where does Super Jack come from?
Sources agree on the parents: Jack Herer, the pine and spice sativa from the Netherlands, and Super Silver Haze, a citrusy, long-flowering haze. Both sides lean sativa, so Super Jack does too.
Who first made the cross is not well documented. Several seed companies have sold their own Super Jack over the years, so different producers may be growing slightly different plants under the same name.
What does Super Jack smell and taste like?
Super Jack smells sweet and spicy first, with a rich, almost buttery note underneath. Reviewers also pick up earth, herbs and a skunky, pungent side, and a few mention pine or tropical fruit on the taste.
Terpinolene is listed as its leading terpene, followed by caryophyllene and pinene. That is close to the usual Jack Herer profile, which helps explain why the two get compared so often. Terpinolene brings a fresh, herbal sweetness, caryophyllene a peppery bite and pinene the pine.
Super Jack effects: what people report
People most often describe Super Jack as energetic, focused and talkative, with a creative, upbeat headspace. It's usually talked about as a daytime strain rather than one for winding down.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry eyes and dry mouth are the most common complaints, and some people say it made them feel anxious, which is worth knowing with any bright sativa.
How strong is Super Jack?
Published figures vary. Some listings put Super Jack around 16% to 19% THC, while others report batches in the low to mid 20s, with very little CBD.
If you're new to it, start with a small amount and wait before having more. The THC and CBD numbers on your label describe the batch in your hand, which matters more than any strain average. Our guide to reading cannabis labels walks through what each number means.
Buying Super Jack in Canada
Super Jack is a less common name than either of its parents, so read the label carefully. Products called Jack or Jack Haze are not necessarily the same cross.
You might find it as dried flower, pre-rolls or vape cartridges. Check the THC and CBD numbers and the packaging date, since fresher flower keeps more of that sweet, spicy smell.
Super Jack vs Jack Herer
Jack Herer is one of Super Jack's parents, and the two share a terpinolene-led profile, so they feel like close relatives. Jack Herer leans sharp pine and pepper, while Super Jack is sweeter, with a buttery, spicy note from its haze side. Both get called clear and focused, and Super Jack is sometimes listed a little stronger. If you want the classic, start with Jack Herer. If a sweeter, spicier take sounds better, try Super Jack.
