Royal Jack Auto: A Strain You Can Grow Anywhere, Thanks to Haze, Northern Light, & Skunk
The Jack Herer strain is equally famous as the man himself, carrying with it a legacy that will stand the test of time. The original photoperiod cultivar has been enjoyed by cannabis connoisseurs the world over, and is now available in an easy-to-grow autoflowering format with Royal Jack Auto. Maintaining the original Herer’s powerful and uplifting sativa-dominant high, the fresh, peppery aroma offers something new and intriguing for those who have yet to crop this beauty.

In many ways, Royal Jack Auto really is like a mini-version of the original; however, given Royal Jack’s autoflowering nature, it can be grown nearly anywhere! After the seeds are germinated, feminized plants will grow quickly and be ready to harvest in just 11-12 weeks.

The High Will Keep Your Motivated All Day Long
The main effect of this strain is a creative and energising high, but thanks to its mix of Haze, Northern Lights, and Skunk genetics, it also gives you a relaxing, stoney indica feeling. Royal Jack Auto’s cannabis seeds feature a Haze-like peppery profile. The smoke is fresh and smooth with a slightly spicy herbal taste, much like the original Jack Herer strain.

Small Plants With Big Yields
Royal Jack Auto will perform well in both indoor and outdoor grows, providing average yields of around 70–120g/plant outdoors and up to 400g/m² indoors. It will not grow too tall, reaching a height of 40–90cm, which makes it ideal for smaller or more discreet grows. Royal Queen Seeds is proud to continue the tribute to Jack Herer, the Emperor of Hemp, with this great autoflowering strain.
