Jack The Ripper Strain

Jack The Ripper is a lemony hybrid that displays strong sativa characteristics and is an invigorating smoke. This is an ideal wake and bake strain as it can be uplifting and energizing, and has gained notoriety due to its potency and because it is a very enjoyable strain.

Jack The Ripper, also known as JTR, is a hybrid created by the breeder Subcool for TGA Genetics. It was made by crossing Jack’s Cleaner with a Space Queen phenotype known as Space Dude. This resulted in an uber-fragrant and highly stimulating hybrid strain.

This slight sativa is a resinous flower with an intensely sour and lemon aroma that stings in the nostrils and acts as an introduction to its taste. Jack The Ripper is a short plant with high levels of THC that can often be too much for novice consumers, so it is best handled with care.

        1. I loved it, I suffer from chronic pain, I had two degenerative disc removed from my neck Nov 1 2016, found out the plate broke in June 2018, had 2 rods put down the back of my neck so my room got bugs mold mildew powdery and my plants kept seeding out on me, have a lot of seeds not sure if there Jack anymore though. With my pain my 2 favorite strains were, Jack the Ripper, and super lemon haze wow did they kick my butt.

        2. Just grew two, one outdoors, one in open air greenhouse. So far what I can say is thrives outdoor, is very pw resistant, fun to grow. This is my first grow, so I’m loving it.
