Royal Critical Automatic was created to retain the very best characteristics of the photoperiod Critical, but with greater ease of cultivation and a much quicker life cycle. Why wait out the extra weeks of flowering when you can crop a Critical harvest in no time? This feminized autoflowering cultivar takes the already hardy genetics behind Critical and adds ruderalis to the mix to speed things up.

With a THC content of 14%, Royal Critical Automatic isn’t quite as potent as the original, which some consumers may enjoy. This hybrid contains significant sativa and indica influence, making it a good smoke during the day to stay productive and focussed, or to use in the evening before bedtime. The high of this strain is characterised by the relaxing and euphoric effects of the original Critical, with less potential for couchlock.

As implied by its name, Royal Critical Automatic will flower automatically, regardless of light schedule. This makes it an easy-to-grow plant that is especially suited to beginner cultivators looking to grow Critical. Even more experienced growers will enjoy the big, dense buds that waft intoxicating aromas at the end of the flowering phase. Scents of wood, spice, and sweetness will dominate the terpene profile. In just 9 weeks post-germination, this Critical variant will be begging for the chop.


Royal Critical Automatic will grow to around 55-65cm in height. Although small and bushy, it has an open structure which allows for greater light penetration to all areas of the plant. This means bigger and better harvests. With yields amounting to 165g/plant of delicious, sweet-skunky buds, there are many reasons why Royal Critical Automatic deserves a special spot in your cannabis garden.

    Title : Super
    Comment : Une variété plus que génial, j'ai fais un suivi photo tous les 2 jours, et ça donne 34 photos plus que superbes. Je recommande cette graine à faire germer dans l'eau 24 heures, utiliser le Eazy Start avec la pointe de la graine vers le haut (la future Racine) c'est un paradoxe mais bien plus efficace puis 3 jours dans un endroit très sombre à environ 24°C. Une fois la naissance de vos bébés un peu jaunâtres en vue, les mettre 24 heure dans un endroit lumineux où vos chouchoux prendront une belles couleur verte puis les mettre enfin dans leur pot de culture de minimum 11 litres.

    Title : Essai transformé
    Comment : Après des faux départs, RQS a renvoyé gratuitement trois graines. Aujourd'hui malgré un substrat pas top, une jolie plante assez basse (35 cm) mais porteuse d'un joli bud bien épais avec quelques têtes annexes bien compactes. On en est à trois mois ... les trichomes semblaient presque mûrs ... mise au noir et après seulement 24 heures stabilisation des trichomes et repartie en flo (nouveaux pistils + nouvelles petites feuilles) ! Du coup elle joue les prolongations dans l'abri de jardin, j'attends que l'ambré se diffuse. Très bonne surprise car c'était pas gagné au démarrage.

    Title : Ottimi semi!
    Comment : Ho piantato 5 semi direttamente in vaso. Premetto che sono alla mia prima esperienza ed ho ottenuto 4 piante di 5 che dopo 1 mese stanno crescendo sane e robuste. Le premesse per il momento sono davvero ottime, adesso non resta che attendere la fiiritura.
