Royal Runtz Feminized Seeds by Royal Queen Seeds – 27% THC, Gelato x Zkittlez Hybrid

Grow Royal Runtz feminized seeds for a premium 27% THC experience that blends euphoric energy with deep body relaxation and a flavor like fruity candy from another dimension.

Are you chasing flavor, power, or both?

Most strains make you choose: do you want a knockout high or a taste that dances on your tongue? Too often, you get one at the expense of the other.

And when you finally find a potent strain, it turns out to be finicky, stretchy, or a magnet for mold. Or you grow a fragrant beauty that barely hits above 15% THC. The compromise is real — until now.

Royal Runtz feminized seeds solve it all. Born from Gelato and Zkittlez, this 50% indica / 50% sativa hybrid delivers sky-high 27% THC, a terpene profile bursting with candy-like sweetness, and a balanced high that’s both mentally stimulating and physically soothing — without the grower headaches.

What Royal Runtz does for your grow and your high

This isn’t just another photoperiod strain — it’s a complete experience. From the first sprout to the final toke, Royal Runtz stands out with its resilience, speed, and sensory overload. Whether you're growing in a closet or a greenhouse, it adapts and excels, rewarding you with dense, trichome-covered buds that smell like a fruit market dipped in frosting.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Royal Runtz in my 2x2x2 m tent with a 600W HPS and living soil — and damn, this strain impressed me. From week one, the smell was insane: like tropical fruit soaked in sugar. I used minimal LST, just to open up the canopy, and she responded perfectly. No stretch, no nutrient hiccups, no mold issues even during late flowering.

The buds packed on fast. By week 8, they were dense, frosty, and turning purple at the tips. I flushed for 10 days, harvested at 70% amber trichomes, and cured for three weeks. The high? A smooth wave of creativity followed by deep relaxation — perfect for unwinding after a long day without knocking me out. If you want a strain that delivers on flavor, potency, and growability, Royal Runtz is a must-try. I’ve already re-ordered for my next cycle.
