Genetics and origin

Auto Purple is based on Purple Fem — the European purple selection by Pyramid Seeds — converted into an autoflowering format. The characteristic forest-berry profile, the violet colours and the balanced effect are all preserved — now with no light schedule and several harvests a year possible. A best seller in the European collection.

Effects

As a balanced 50/50 hybrid, Auto Purple offers a two-phase effect:

Euphoric start — a pleasant mood lift and serenity
Physical relaxation — the indica share brings deep muscle relaxation
Balanced serenity — ideal for the evening or creative moments

At 18–20% THC it's more accessible than the Fem version — ideal for newcomers to purple genetics.

Aroma and terpene profile

The forest-berry fruit profile of Purple Fem is fully preserved in the autoflowering version — intense, sweet, fruity. The violet tones are present even under continuous 18/6 lighting, but intensify at cooler temperatures in late flowering.

Terpene	Typical impressions	Contribution to the profile
Myrcene	Earthy, fruity, sweet	A fruity base, supports relaxation
Caryophyllene	Spicy, peppery, warm	Spicy depth, balances the berry sweetness
Linalool	Floral, slightly sweet	A calming floral note
