What is an Autoflowering Cannabis Seed?
An autoflowering cannabis variant is genetically different from other variants solely because of its growth cycle.

This means that the harvesting time does not take more than a few weeks or so.
This unique feature allows growers of autoflowering cannabis to harvest multiple crops in a single season.
