autoflowering plants are called ruderalis (google it for more info). the fact that they flower under 24 hrs light means that there is no veg time, the plants automatically go right into flowering. thus, it is reported that you can't clone these strains. just as they have their drawbacks, they are perfect for some applications. for instance, if you didn't want to clone or wait all summer for flowering (outside) you could plant a bunch of these and harvest in a couple months. you can get multiple crops out of one summer.
