BCN Critical XXL: Supreme Spanish Genetics

The BCN Critical XXL is a new and improved version of Critical genetics. This strain was bred in Spain by using elite, basque country clones of Kritical Bilbo and Critical +. Then this cross was crossed again with Critical Mass, resulting in an easy-to-grow strain with a supreme high and a wonderful citrus fragrance.

When growing BCN Critical Mass, give her ample space since she’ll grow to a medium height. She’ll benefit from topping and the screen of green method to improve her already exceptional yields.

Feed her with enough light by using at least a 600W HID lamp. When vegetating, she’ll enjoy an 18/6 light schedule and when she’s ready for flowering, flip her into a 12/12 lighting schedule.

She’ll love to grow indoors or outdoors and will be ready in about 11 weeks of flowering. Keep her in at least 10L containers to give her roots enough space to thrive.

  • Nutrient Requirement: Standard
  • Watering Schedule: Adequate
  • Indoor Humidity: Less than 65% RH
  • Indoor Temperature: Less than 32°C
  • pH (Hydro): 5.5
  • EC: 1.6

Critical Success

After the first inhale, you’ll find yourself indulging in BCN Critical XXL again and again. When the acidic lemon flavor leaves your tongue, you’ll be in for a wild ride. This strain will bring you to soaring heights that will endure for hours. This strain is meant for those who want an easy-to-grow strain, but with world class flavor and strength.

    • Advantages
      Biggest producer from my three (biggest pot) , lovely pinecone buds, decent yeild. Topped twice and grew her along horizontal supports to keep the hight down. Resulted in about 25 smaller branch's growing vertically with each becoming a big fat pine cone.
    • Disadvantages
      Not a lot. My training was a bit brutal and I snapped a few lats to get what I wanted. This method required lots of mini supports.
    • General impressions
      Lovely to smoke and a good social buz, nice smell from the cured product, buds looked awesome.

    Hello mxdup,

    Thank you for your feedback. We are glad you were pleased with the harvest. The minor probability of the appearance of male plants is always present and we are glad that this did not prevent you from getting a good yield. Hope we'll see you back!
    Respectfully, Herbies Seeds
