Auto-Flowering seeds are ideal for novice to intermediate growers, as they tend to be smaller and do not depend on seasons. Auto-flowering cannabis seeds are produced when a sativa, indica, or both are crossed with a ruderalis variety. Ruderalis is a cannabis variety that possess auto-flowering characteristics which are not found in both sativa and indica. When ruderalis genes are infused with a sativa or an indica, the cross produces a hybrid cannabis strain that flowers automatically without the need to change light cycles.
Auto-flowering cannabis plants have their own biological clock and therefore are not affected by photoperiods. This means they usually have a very short vegetative stage, resulting in a shorter plant, but that can be grown at any time of the year. All auto-flowering strains contain approximately 10% ruderalis.
