Royal Jack Automatic

Jack Herer is a great strain named after a great man. He was a tireless cannabis legalization activist and author of the book The Emperor Wears No Clothes, also called the Hemp Bible. Herer was a powerful voice in the cannabis movement up until his death in 2010. Now, his legacy can be celebrated in autoflowering format, with the precocious Royal Jack Automatic.

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 10 weeks.

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 features a Haze-like peppery profile. The smoke is fresh and smooth with a slightly spicy herbal taste, much like the original Jack Herer strain.

Royal Jack Automatic 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.

    Title : Probably defective seeds
    Comment : So this is my second experience with RQS, i ordered Royal Jack pack of 3 seeds but unfortunately had very bad result... Two of them had germinated well, but as soon as they popped up, they died. It looked liked they dried out in 1 day after cooming out from soil, anyway i am 100% sure that waterring was enough, i was germinating one after one, so on second time i tryed totaly different soil, but same thing happanied, and third seed i desided to germinate with paper towel method but it didnot germinate at all... Dont think that its my fault because for both times i used PH balansed potting soil with perlite, and low wattage LED light to not burning them. By the way previously i ordered 3 Amnesia Haze Auto seeds, and everything was fine with them...

    Title : Life saver for the chronically depressed
    Comment : This strain is generally not considered a medical strain, But for me it is the lifesaver i have always been looking for. This strain does all that i wish psychiatry could offer but do not. This autoflowering variety is great for anyone who wishes to rejoice in the glory of Jack Herer but cant grow outside, As Jack Herer often grows quite large. This variety saves a lot of space and as i said...if you are suffering from depression and cant get the help you need from psychiatry...try this one. I bet my left ball you will not be dissapointed.

    Title : Very good quality!
    Comment : The amount of THC-crystals are insane. It grew very nicely and supercropping plus topping, were no problem. The plant recovered from the stress in no time. I had it grow 2 weeks longer, so it could unfold it's true potential. I strongly recommend you, to give it a little more time. Cheers :)

    Comment : I had seeds from RQS the third time and everytime all the seeds (like 20 or so) germinated. That's a quality promise that not only fancy looking in the shop.

    Comment : K.A. warum, aber von 5 Samen keimt meist nur einer... - gegen die Qualität der Pflanze oder den Service von RQS ist nichts zu sagen. Bester Kundenservice ever...!

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