Grand Daddy Purple: The Ultimate Indica Hybrid

Created by Big Head Seeds, Grand Daddy Purple is a well-known Indica-dominant hybrid that took the cannabis community by storm in the early 2000s. Since then, she has dominated thanks to her well-established genetics that combines the best of Big Bud and Purple Urkle.

If that wasn’t enough, she offers potential yields of up to 500 g/m2 in lightning-quick speeds pf just 9 weeks of flower. Her Indica-dominant genetics are evident in her stature which is often short and bushy, some light pruning of any large fan leaves is recommended to ensure optimal light penetration of every bud to give your yields the boost they need.

    • Advantages
      Amazing strain. Half to whole pound yields when grown outside. I grew five and had three different pheno types and all were incredible. One was 8 feet tall over n16 feet around. Potent bud . Covered in trichomes and great bag appeal. All of mine had more of a sativa leaning cross. Highly recommend strain. If you finish it late or indoors, drop the night time temps to 45 or 50 and she turns an amazing purp color . I love all of Big Heads strains. grow this
    • Disadvantages
      I honestly can not think of anything bad to say about this strain. Maybe I could say it gets too big? Or that it produces too much bud?
    • General impressions
      This strain is big and hardy. It produces huge , tasty, beautiful buds.
