Girl Scout Cookies: The Ultimate Hybrid Cannabis Strain

Girl Scout Cookies is a feminized cannabis strain developed by Black Skull Seeds which came about as a cross between Durban Poison – a fantastic Sativa-dominant hybrid with excellent resin production – and O.G. Kush to yield a strain has reshaped the face of cannabis culture with her incredible attributes.

Growing Girl Scout Cookies is a valuable experience as she requires a little maintenance during the vegetative phase and early flower to ensure a wide, flat canopy. This can be taken a step further with the use of training techniques such as LST (low-stress training) and topping in conjunction leading to a massive improvement in her yields and an increase in the size of her buds. Indoor yields for GSC are up to 450 g/m2 after 55 – 60 days in flower while outdoor growers can bring in as much as 500 g per plant. Here is some further information to help you grow this strain:

  • Tall height – GSC can grow as tall as 1.5 m both indoors and outdoors.
  • Max EC of water – 1.5 in veg, up to 2.0 in flower.
  • Water pH; 5.8 – 6.0
  • Recommended grow medium: Coco Coir – excellent results when grown in a 70:30 mix of coco and perlite.
  • Recommended nutrients: CANNA COCO range.

Packed Full of Flavour

The original Girl Scout Cookies was also known as Thin Mint Girl Scout Cookies due to her sweet, fresh, mint-like taste and a pungent aroma, and Black Skull Seeds’ GSC is no different! A flavour-loaded terpene profile makes for a very pleasant consumption and leads to a long-lasting high with deep body relaxation.
