Overview

Hybrid · Cannabis Seeds · Autoflowering seeds

Royal Critical Autoflower (Royal Queen Seeds) Feminized is a hybrid strain from our autoflowering seeds range testing at 14% THC. Commonly reported effects: relaxing. Flavour notes: sweet and skunk.

Highlights

  • Sweet meets skunky: A rich aroma of sweet earthiness with a skunky, pungent edge.
  • Critical Mass lineage: Critical Mass x ruderalis cross, 50% indica, 15% sativa, 35% ruderalis.
  • Compact indoor grower: Stays 60-80 cm tall, open canopy makes light distribution effortless.
  • Smooth evening effect: Relaxing and calm, best saved for the end of the day.

About this format

Cannabis seeds are sold as collectable souvenirs and for the preservation of genetics. Feminized seeds grow into female plants, autoflowers switch to bloom on their own regardless of light schedule, and regular seeds produce both sexes for breeding. Germination is illegal in many countries — know your local law before you buy.

From the supplier

Royal Critical Autoflower: Critical Mass Muscle in an Auto Package

Royal Critical Autoflower from Royal Queen Seeds brings the reputation of Critical Mass into a compact, schedule-free format. The genetic split, 50% indica, 15% sativa, 35% ruderalis, tells the story clearly: Critical Mass contributes the indica-dominant character, the yield potential, and the vigour that made the original famous; the ruderalis side removes the need for any light cycle management. The result is an indica-leaning auto that has picked up multiple awards in Spain, earned on the strength of what it actually produces rather than what it promises.

Small Footprint, Straightforward Grow

Indoor plants stay between 60 and 80 cm, which means no aggressive training to keep the canopy in check. The bushy, open structure is genuinely useful here, light reaches lower bud sites without much intervention, and each plant can deliver around 60 g at harvest. LST works well if you want to push that figure; topping is a different matter with autos, and many growers skip it entirely. Seed to harvest runs 10 weeks. Grow difficulty is rated easy, and that tracks, this is a solid first autoflower for anyone new to the format, and a low-maintenance option for experienced growers who want reliable, repeatable indoor cycles without the fuss of a more demanding strain.

Sweet, Skunky, and Built for the Evening

The aroma is a straightforward duality: sweet and earthy up front, with a skunky, pungent edge underneath. It's not subtle, but it's not harsh either, the smoke is smooth, and the effect follows the same character. Relaxing and calming, this one is evening-leaning without tipping into heavy sedation. If you're used to more cerebral or energetic autos, Royal Critical Autoflower sits at the opposite end of that spectrum. Think of it as the wind-down counterpart to a daytime sativa, less about sparking ideas, more about switching off after a long day.
