Why Choose Grapefruit Auto
  1. Authentic Fast Buds genetics, from a named breeder.
  2. Resistant to mould and mildew. The most useful thing on this page for anyone growing outdoors in a humid climate, and rare enough that no other seed in our range states it.
  3. Genuinely compact. Short and stocky at 80 to 120 cm, which is what makes it suitable for a balcony, a terrace or a small indoor space.
  4. Strong yields with minimal maintenance. 400 to 550 g/m² indoors and 50 to 250 g per plant outdoors.
  5. An unusual flavour. Sweet and sour grapefruit with a floral edge, rather than the sweet berry profiles that dominate the rest of the range.
  6. Multiple outdoor harvests per year are possible, thanks to the short cycle and the resilience.
Growth Characteristics

Whether grown indoors or outdoors, Grapefruit Auto delivers abundant yields with minimal maintenance. It is a short, stocky hybrid that thrives in limited spaces, reaching 80 to 120 cm, and it produces 400 to 550 g/m² indoors or 50 to 250 g per plant outdoors across a 9 to 10 week cycle.

It flourishes in a variety of climates and is highly resistant to mould and mildew, which is what makes multiple outdoor harvests per year realistic rather than optimistic.

Growing tips:

  • Use Sea of Green (SOG) techniques to maximise yield in small spaces.
  • Low Stress Training (LST) can improve growth and overall bud production.
  • Keep humidity levels balanced to prevent mould, even given the resistance.
  • The short stature suits balconies, terraces and back gardens, which is worth knowing if you do not have an indoor space.
Who Should Grow Grapefruit Auto
  • Beginners. The resilience and low maintenance requirements make it straightforward to grow.
  • Growers with small spaces. The compact size suits limited indoor or outdoor setups.
  • Anyone growing outdoors in a humid climate. The mould and mildew resistance is the reason.
Storage and Germination

Storage: keep the seed in a cool, dark place, preferably in an airtight container in the refrigerator. Not the freezer.

Germination: the paper towel method is reliable.

  • Place the seed between two moist paper towels.
  • Keep it in a warm, dark location.
  • Check daily, and transplant to soil once the taproot emerges.
