    People talk a lot of smack about autoflowering cannabis seeds, but newer breeds like Critical Express are putting those rumours to bed. These intense autoflowering seeds have revved-up power & yields to unheard-of levels and kept a full-bodied flavour and aroma, something that seemed impossible in the past.

    Critical Express Seeds are a superior mix of multi-Cup winning Critical Mass and Lowryder 2, the absolute best Ruderalis hybrid. As a result, this new hybrid gets just a smidge of autoflowering genetics that doesn't water-down the original characteristics.

    • Critical Express Sets a Higher Standard for Autoflowering Seeds!
    • Critical Mass X Lowryder 2 – Epic!
    • 65-Day Cycle - 12% THC - 100 gr/seed Yields!
    • Clean, Fruity Flavours that Linger – A Real Mouth-Dryer!

    These feminized autoflowering seeds have everything you’re looking for in premium beans of any type. Critical Express Auto finishes in 65 to 68 days from seed, kicks ass with 12% THC & 100-gr yields, dries your mouth with a long-lasting, fruity flavour and has that classic Critical aroma that’s as energizing as a Red Bull! It’s the sh*t!

    Positronic’s Critical Express Feminized relaxes your mind and your body with a potent, balanced and pleasant high! It doesn’t lock you to the couch, but who wants to be totally zonked anyway?

    Back in the 80s, Positronics was THE source for high-quality Dutch Cannabis Seeds. Founded by Wernard Bruining, a true marijuana legend, this iconic seed bank went bankrupt in 1996 and distributed their gene pool including Northern Lights, White Widow and Skunk #1 to a variety of trusted friends. A few years later, Spanish breeder Sebastian Sebas convinced Wernard to restart the business in Spain. Now, you can get the quality you expect from the Positronics name in both old-school strains and brand-new genetic blends. Check 'em out!
