15 Highest Yielding Autoflower Strains

By Last updated on June 16, 2021No Comments

Autoflowering cannabis strains are becoming popular for some critical reasons; they grow easily, fast, and small.

Whether you are looking to grow a fast-producing indica or a hybrid sativa, there is probably an autoflowering strain that can guarantee impressive quality weed and an even more impressive high yield.

An autoflowering plant can feel more simple to grow than a traditional photoperiod strain of cannabis because they do not need special light schedules. With autoflowering plants, you basically just plant a seed and wait. Keep your plant alive and healthy with plenty of light and you will harvest buds in 2-3 months.

Why should I grow autoflowers?

Autoflowering cannabis strains come with a lot of benefits for home growers:

  • Quicker harvest: Autoflowering strains give you buds sooner with less of a time commitment. 2-3 months from seed to harvest compared to 3-5 months on average for photoperiod strains.
  • Easy lighting conditions: Flowering photoperiod strains need a daily 12-hour dark period and even a small light leak can cause plants to become stressed. That means no checking on your photoperiod plants during their “nighttime.” Autoflowering plants do not care about light periods so you can check on them at any time.
  • Small plants: It is easy to accidentally produce enormous photoperiod plants, while most autoflowering strains stay relatively small due to the short growing period. That makes auto-flowering strains a great choice for growers who prefer a small or easy-to-hide garden.
  • Flexibility: Photoperiod plants must be grown in “batches” to ensure all plants make buds at the same time. That is about 3 harvests a year if you never take time off between grows. Many home growers prefer a steady supply of buds as opposed to getting just a few big harvests a year. You can plant an autoflowering seed whenever you want and always be just 2 months from harvest.
  • Excellent yields: Despite the short time to harvest, quality autoflowering strains get comparable yields to photoperiod plants of the same size. That is because they receive up to twice as many hours of light a day while buds are forming.
