The strain that changed cannabis culture and has astonished weed lovers for more than a quarter-century is now available as a feminised variety!
The potency of this branch of the cannabis family tree is so notorious that 'skunk' is often used as a term for any powerful ganja. Breeders regard Skunk #1 as the benchmark of uniform, reliable performance and her rock-solid genotype has influenced a hundred modern hybrids. Skunk #1's energetic performance and bountiful yields demonstrate the true meaning of hybrid vigour. Growth and flowering are mostly-Indica in appearance, though Skunk plants gain more height than pure Indicas when blooming.

Flowering is very fast and Skunk #1 produces robust stems and branches to support her superior yields. Short internode gaps explode into dense, rounded bud-clusters which merge into huge, heavy colas by harvest time.
Skunk #1's Sativa genes have a subtle effect on flower structure plus a wonderful influence on her effect - a stunningly potent combination of stone and high!
