CBD Auto 20:1 feminized seeds


CBD Auto 20:1 Strain Info

CBD Auto 20:1 is a feminized autoflower created by Fast Buds as its first entirely medicinal cannabis strain. Sporting sweet and enjoyable flavors with hints of fruit and honey, this CBD powerhouse offers a variety of therapeutic properties, alleviating pains and disorders with only mild psychoactive effects. Her trichomes are especially useful for creating oils, tablets, creams, and edibles.


Although her lineage is rather murky, CBD Auto 20:1 has proven to be a great treatment for various ailments. This feminized autoflower has been hybridized by combining both Indica and Sativa genetics.

Flowering Time

CBD Auto 20:1 plants take about 9-10 weeks to complete their entire lifecycle from seed to harvest.


Despite her moderate size, this strain produces large yields – expect to fill your jars with 350-450g/m² (133-171oz/ft²) for indoor-grown plants and 50-170g/plant (2-6oz) outdoors.


CBD Auto 20:1 produces mild, relaxing, and moderate effects, meaning that she’s well-suited for non-regular users.


Medical Properties

Thanks to its large quantities of CBD and low THC content, CBD Auto 20:1 is a great choice for therapeutic purposes such as relieving tension, chronic pain, anxiety, insomnia, and inflammation.

THC and CBD Levels

CBD Auto 20:1 is a heavily CBD-dominant cannabis strain usually testing at 20% CBD and 0.3-1% THC.

Smell and Taste

The terpene profile of CBD Auto 20:1 is a pleasant addition to her calming effects. The plants sport sweet and seductive flavors with hints of fruit and honey.


Grow Tips

This feminized autoflower grows quickly and vigorously, producing lime-green buds with numerous dark red, even brown pistils shooting from dark green, fat buds. The CBD Auto 20:1 plants usually grow bushy and have a solid main cola. They typically reach around 70-90cm (27.5-35.4 inches) in height. A compact size, coupled with an increased resistance to pests and diseases, makes this strain well-suited to almost every environment and setup, even in harsher climates.

  • During the flowering period, the strain is hungry for nutrients that are needed to build her dense, elongated buds.
  • An 18/6 light schedule allows for maximum plant growth.
  • Like most autoflowers, CBD 20:1 makes a great choice for Sea of Green setups that can help maximize yields.
  • We recommend that you don’t wait for the trichomes to turn amber – harvesting when most of them are still milky-white will give out the most CBD.

Designed for both recreational and therapeutic use, the CBD Auto 20:1 feminized autoflower cannabis strain is a perfect choice for those who want to steer clear of the psychoactive effects of THC. Place an order online at Herbies in just a few easy steps to grow your own medicine tree.

      I have nothing negative to say or comment on with this plant, it was a breeze to grow, topped, lst'd, au natural it doesn't matter how you want to grow it, the plant is tough👊
      You can expect fat juicy greasy buds.
    • General impressions

      This is one amazing tasting plant, its so smooth and creamy. 10/10 in flavor I have been smoking it for a few day's now and Im blown away. I don't get the high, but I get a very calming wave of joy after every bong rip.
      The joints are amazing too wow, so flavorfull again, its the weirdest stuff, you dont get high..
      The rosin pressed it terrible with a measly 1.3g from 8g
      I think everyone should give this one a go, there must me someone you know who might benefit from this strain.
      I will be growing this again 100%, sooner than later

    • General impressions

      Overall this has been an awesome growth. Will be growing more autoflowers after this. With high frequency fertigation of course🙂 The smell was quite prominent after week 3 of flowering with earthy with mild fruity aroma but still manageable with an inline carbon filter.
