Auto Jack Hammer strain is available as feminized autoflowering, or as feminized photoperiod seed. This version is feminized autoflowering. This means, it will develop as a female plant, that will automatically switch to flowering phase, based on its age.


Its genotype is a mixture of sativa, indica and ruderalis. The ruderalis genetics made this strain a little bit smaller in size, but a fast flowering one. It originates from Mexican, Colombian, and Thai sativa, combined with USA indica. Some of the famous ancestors of this strain are Northern Lights #5, Skunk #1 and Original Haze. The final cross breeding, that resulted in this amazing strain, was between our Jack Hammer and an unknown ruderalis strain.


This strain is autoflowering, it can be grown almost anywhere. Indoors, it takes from 7 to 8 weeks to finish the flowering period and produces up to 400 grams per square meter. Outdoors, the plant is ready to be harvested after 10 to 11 weeks after planting the seed and produces anywhere from 50 to 170 grams. It can reach from 80 to 160 centimetres in heights.


Jack Hammer Automatic grows buds that are very similar to the original Jack Hammer. They can contain up to 16 % of T and a medium amount of C, making it a great choice for people with low T tolerance. The main effect is an uplifting and creative Sativa high, but thanks to Jack Hammer's mix of Haze, Northern Lights and Skunk, this strain also gives you a relaxing Indica feeling. Jack Hammer Automatic has a Haze-like, peppery aroma.
