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 Automatic. 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 Automatic 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 Automatic'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 Automatic will perform well in both indoor and outdoor grows, providing average yields of around 2.5 – 4.2 oz outdoors and up to 14.1 oz/m² indoors. It will not grow too tall, reaching a height of 1.3 – 3 feet, 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.

    Title : Very nice but do not top unless using scrog
    Comment : Ran 3 in dwc, definitely do not top this strain if you are not using a scrog net, The one I topped was the most vigorous and it produced tons of larf mostly due to lack of light penetration But the other 2 I let go and produced some very nice flowerers Would definitely buy again

    Title : Unbelievable in veg phase
    Comment : a little last start since one seed did not germinate but started another and it pick up so fast its about the same size as others, plant looks fantastic and firm strong growth in veg phase, transitioning into flowering but wonderful genetics.

    Title : Molto buona
    Comment : Una varietà molto rapida e relativamente semplice anche se mi è capitato più di una volta che i germogli non riuscissero proprio a crescere, le rese sono buone per una piccola dotazione personale e l'aroma insieme all' effetto un po' più motivante la rendono quasi perfetta

What CBD "medium" mean in percentaje?

Royal Queen Seeds Team

We don't usually specify the exact CBD content of our THC dominant strains because it's partially dependent on the growing environment, feeding schedule, and several other factors. Below is an example of average values: • Low CBD: Below 1% • Medium CBD: 1-3% • High CBD: 5-8%

From Ricardo | 2018-05-25 17:26:21

Hi, I'm a bit confused about the yields. Are the shown values of 70-120g dried or fresh harvested weights?

Royal Queen Seeds Team

We are referring to the dry weight.
