“Royal Runtz Auto” Feminized Cannabis Seeds – Royal Queen Seeds

Royal Runtz Auto by Royal Queen Seeds: Versatile, tasty and productive!

Each of us is particularly fond of one or two strains. These strains tick all the boxes: they produce good yields, offer pleasant effects and taste amazing.

After growing Royal Runtz Automatic, many growers quickly add this strain to their favorites. Its impressive versatility will probably win you over too.

The genetic background of Royal Runtz Automatica

To create Royal Runtz Auto, our breeders simply crossed the photoperiod Royal Runtz with a ruderalis specimen. The original variety quickly gained a lot of popularity right after its release: growers couldn’t resist its outrageous THC levels of 27% and its sweet taste.

We have now decided to add some autoflowering genes to the mix for faster growing cycles and more discreet plants.

Effects and aromas of Royal Runtz Autoflowering

What is the difference between Royal Runtz Automatic and the original strain? Sure, her THC levels don’t quite hit the 30% mark, but 19% of this beloved cannabinoid means the plant has some potency for an autoflower.

After a bong or joint loaded with its flowers, expect an energizing sensation to invade your body and mind. And that its sweet and fruit flavors make every puff a delight.

Growing characteristics of the Royal Runtz Auto Feminized cannabis strain

If you want good harvests as quickly as possible, Royal Runtz Auto is for you. When grown indoors, she reaches a height of 70–100cm and yields 350–450g/m². With a little training you can even grow it in hidden cabinets and small closets.

Outdoors she reaches heights of just over 120cm and produces rewarding yields of 70–100g per plant. After placing the seeds in the ground, you will only have to wait 10–11 weeks before harvesting its flowers.
