Auto Purple feminized seeds (Pyramid Seeds)


Auto Purple Strain Info

Auto Purple is an autoflowering cannabis strain created by Pyramid Seeds as part of a project to yield a brightly-colored autoflowering and fast-growing plant that completes her grow cycle in minimal time from seed. Her lineage of Sativa, Indica, and a Ruderalis hybrid make her suitable for growers of all skill levels and exemplifies the power of autoflowers.


To achieve such tremendous results, Pyramid Seeds ingeniously crossed the widely loved Purple and a Ruderalis for the gorgeous Purple autoflowering variety that is Auto Purple.

Flowering Time

She’s a fast-growing plant that completes her grow cycle in a flowering time of 50-65 days from seed.


Indoor yields for this beautiful strain are about 400g/m2 (1.3oz/ft2), while outdoors, growers can expect to bring in a harvest of between 40-180g/plant (1.4-6.3oz/plant), with some growers managing 300g (10.5oz) per plant!


Experience a smile from ear to ear as the joy of Auto Purple sets in with her mellow high that leaves you feeling jolly, along with a gentle body buzz that relaxes you for hours on end. Mild enough for novice smokers but warm and fuzzy enough to delight a connoisseur, Auto Purple is all about balance.

Medical Properties

Auto Purple works well for mild anxiety and stress, with a softly relaxing yet uplifting effect and medium THC content.

THC and CBD Levels

Her happiness-inducing high is thanks to a THC content of 13%, paired beautifully with CBD levels of 1% and the presence of 0.4% CBN.

Smell and Taste

She also happens to have an equally impressive smell and taste, producing a sweet, floral aroma with hints of berry and citrus terpenes to complement it. Oh, and don’t forget about those skillfully placed hints of earth that linger on the tongue as you let out an “ahh” of relaxation.

Grow Tips

As the name suggests, Auto Purple has a brightly colored appearance of purple with specks of orange. Autoflowering strains like her are fantastic for those looking to get into growing, as their short height, fast returns, and ability to be grown without a fixed photoperiod make them ideal for cultivation in small spaces. Due to her slightly lower stress tolerance, all training should be limited to low-stress techniques such as light defoliation. Here is some further grow info to help you grow this strain:

  • It grows to a final height of 50-90 cm (19”-35”) indoors and up to 1.2m (47”) outdoors – perfect for stealthy growers!
  • We recommend using 300W LED during the vegetative stage and 600W LED during flowering.

    • General impressions

      I decided to grow Auto Purple by Pyramid Seeds in Soil + LED.
      77 days from seed to harvest.
      Auto Purple was the fastest blooming lady in my garden. It grew one main stem with minimal side branches. During late flower it is necessary to stake and support the main stem as it could snap under the weight of its flowers.
      Can definitely see a Sativa and Ruderalis dominant plant during growth.
      Nice strong racing Sativa/THC heavy buzz with no couch-locking effects. The high lasts a long time (between 2-3 hours for me) and gently relaxes during the later stages.
      Not a good yielder but in terms of quality it is recommendable. I wouldn’t have it as the only lady in my garden and suits someone who likes to grow multiple varieties at once.
      A good novelty strain that would easily find a place in your garden.
