Key Lime Jack strain guide
Key Lime Jack is a hybrid from Maven Genetics, a cross of Bling Cheesecake and the classic Jack Herer. It's known for a bright, sour lemon-lime smell and a lively, creative feel, and it's one of the stronger strains on paper, with listings around 30% THC.
Where does Key Lime Jack come from?
Key Lime Jack is credited to Maven Genetics. The cross is consistent across listings: Bling Cheesecake with Jack Herer, the Dutch sativa named after the cannabis activist.
Where sources differ is the balance. Strain databases list it as an even hybrid, about half sativa and half indica, while Maven's own product descriptions present it as sativa-leaning. Either way, the Jack Herer side shows in how people describe it: clear and upbeat rather than heavy. If the indica and sativa labels confuse you, our guide to indica vs sativa explains why they only tell part of the story.
What does Key Lime Jack smell and taste like?
Lime leads, just as the name promises. People describe sun-ripe limes and sweet lemon-lime, sharp and a little sour, with skunky funk, pine and earthy soil underneath. The taste follows the smell: citrus on the inhale, with some people noticing a creamy, almost vanilla softness, and a skunky, earthy finish.
No source we found publishes a lab-backed terpene breakdown for Key Lime Jack, so we've left that blank rather than guess. If your package lists terpenes, that tells you more about your batch than the name does.
Key Lime Jack effects: what people report
People most often call Key Lime Jack energetic, creative and euphoric, with a focused, sharp-minded feel and a long-lasting high. Several reviews mention happy and giggly moments, and a few say it stays easygoing rather than racy.
These are experiences people report, not promises. A strain this strong can hit harder than expected: reviewers mention dry mouth, dry eyes and dizziness, and one person warned it can feel spaced out. How it lands depends on the product, the amount and your own tolerance.
How strong is Key Lime Jack?
Published listings put Key Lime Jack at about 30% to 32% THC, with very little CBD. That's high by any measure, and the figures come from a small number of sources, so your batch may differ.
If you're not used to strains this strong, start with a small amount and wait before having more. Check the THC and CBD numbers on your label, and see our guide to reading cannabis labels if you're not sure what they mean.
Buying Key Lime Jack in Canada
Read the label carefully. Some products combine Key Lime Jack with other strains, and the name is easy to confuse with Key Lime Pie, which is a different strain entirely.
Check the THC and CBD numbers and the packaging date. Citrus smells fade with time, so fresher flower is more likely to have that sharp lime note.
Key Lime Jack vs Jack Herer
Jack Herer is Key Lime Jack's best-known parent. Jack Herer leans pine and spice, with a clear, focused reputation that has kept it popular for decades. Key Lime Jack swaps much of that pine for sour lime and sweet lemon, and it's usually listed well above Jack Herer in THC. Both get described as creative and upbeat. If you like classic pine and spice, start with Jack Herer. If you'd rather have bright citrus and more strength, try Key Lime Jack.
