Jack the Ripper, also known as JTR, is a Sativa-driven hybrid with medium THC levels ranging up to 17%, achieved following a crossbreeding project involving Space Queen and Jack's Cleaner. Flavor-wise, this sought-after cultivar brings an enticing blend of citrus (think lots of lemon), pine, and more fruity notes. Regarding effects and potency, Jack the Ripper delivers a mentally energizing, creativity-inducing, and focus-enhancing high with long-lasting effects, ideal for productive afternoons and daytime use. Main medical issues to be addressed with this strain are Alzheimer’s, recurring migraines, and anxiety-related problems. High doses can induce paranoid thoughts, so beware if you’re prone to that. Growing these plants means you need to provide ample vertical space and prepare for aromatic ladies that require odor control when grown indoors. They need no more than 60 days of flowering on average to produce nice yields, making for a quick turnaround for your efforts. They are considered to be challenging to grow.
