Sativa-dominant autoflowers tend to take slightly longer with average growing time times of approximately 12 weeks whereas Indica-dominant autos normally take to 8-10 weeks to fully grow.

An average sized autoflower yield is between 1-3.5 ounces per plant (30-100 grams). However, the yield of a plant varies widely depending on genetics, growing conditions and environment. In the right conditions and given some LST training our high yielding autoflowers can produce up to 5 ounces (150 grams) per plant.

During the final few weeks of the flowering stage, you should start to monitor the trichomes of your plant using a magnifying glass to help you identify the signs of maturity. The pistils will begin to darken and curl in and once around 60-70% of the trichomes have turned a cloudy colour they are ready to be harvested.

Yes. Autoflower plants grow to around 100cm tall making them much easier to grow indoors. They also flower automatically, which takes the hassle out of requiring different lighting schedules.
