Purple Auto: An Easy-to-grow Autoflower with Excellent Results

Purple Auto is an autoflowering cannabis strain created by Pyramid Seeds as a cross between Purple and a ruderalis as part of a project to yield a brightly-coloured autoflowering in a fast-growing plant which completes her grow cycle in 50-65 days from seed.

Suitable for growers of all skill levels, strains such as Auto Purple exemplify the power of autoflowers. Autoflowering strains 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. Indoor yields for this beautiful strain are about 400 g/m2 while outdoor growers can expect to bring in up to 300 g per plant. Due to her slightly lower stress tolerance, all training should be limited to low stress techniques such as light defoliation. Here is some further information to help you grow this strain:

  • Medium height – grows to a final height between 50 – 90 cm indoors and up to 1.2 m outdoors!
  • Max EC of water – 1.1 in veg, up to 1.4 in flower.
  • Water pH; 5.8 – 6.0
  • Recommended lighting: Veg: 315 W CMH, Flower: 600 W LED.
  • Recommended nutrient range: General Hydroponics General Organics range

Bright Purple and Covered in Crystals

As the name suggests, Auto Purple has a very brightly coloured appearance, purple with specks of orange, and an equally impressive smell and taste – a sweet, floral aroma with hints of berries and citrus. Her delicate aroma matches the mellow effect brought on by her 13% THC and 1% CBD content.

      I really enjoyed this strain! She’s my favorite! So easy to grow and a good yielder on a windowsill.
    • Disadvantages

      The purple is so intense, and the high is a very mellow one that leaves you feeling great. The taste is incredible too, just like strawberry jam. Love it!

    • 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.
