    There are many cannabis growers and users who enjoy the benefits offered by small autoflower plants. Dwarf autoflowering strains are easy to grow and lead to fast harvest times. In addition, small autoflowers are compact enough that you can grow them literally anywhere with little effort. Therefore, here are ten of the smallest autoflower strains available.

    Advantages of growing a small autoflower (dwarf) plant

    In addition to how quickly they mature and bloom, offering harvest times much sooner than normal, dwarf auto plants have been genetically modified to be as small and compact as possible. This works well for growers looking to increase their grow medium, as well as those in less hospitable climates.

    Because of their size, small autoflowers can easily grow in areas with limited capacity such as cupboards, balconies, and even in small gardens or hidden under bushes. Being such a small size, dwarf autoflower seeds often don’t require the support structures needed by regular plants, and the potent smell of small autoflower plants is often much milder than their regular counterparts.

    In terms of small autoflower strains, the Blue Cheese strain is currently the shortest autoflower available. This tiny autoflower has a height of between 40 and 70 cm when grown indoors. If grown outdoors, this strain can reach a maximum of 110 cm.
