The Top 6 Classic Autoflowering Cannabis Strains

Autoflowering strains are very popular within the cannabis growing community, and are often seen as good introductory varieties due to their ease of cultivation. Unlike photoperiod strains, autoflowering strains don’t require a change in the light cycle to initiate flowering. This makes them slightly less complex to cultivate, and therefore, more appealing to beginner growers.

Most varieties are compact and small in stature, making them ideal to grow in limited amounts of space. This small size is also favoured by growers who like to keep their operations discreet.

Autoflowering strains are also extremely fast to grow, transitioning from a seed into a plant full of flowers in only a couple of months. These varieties were created by combining genetics from Cannabis ruderalis with indica and sativa strains.

CANNABIS RUDERALIS

Ruderalis is a subspecies that evolved in northern regions of the world with short summers that feature long days. It adapted to such unique conditions by flowering independently of light cycle dictation.

Ruderalis plants themselves are short, weed-like, and low in desired cannabinoids. However, the genetics from these plants, when crossed with select photoperiod strains, results in hard-hitting varieties that are both easy to grow and loaded with flavour and potency.

Below is a list of the top classic autoflowering strains.

ROYAL DWARF

Royal Dwarf was created by crossing Skunk with ruderalis genetics. This strain is perfectly described by its name; its compact size and structure make it ideal for growing in miniature indoor spaces. Royal Dwarf is the strain of choice for discreet micro-growers, easily fitting within a modified cabinet or drawer. The flowers of Royal Dwarf are also dense and compact, featuring a THC content of 13%, resulting in a mellow yet pleasant high that stones the body. Each hit of Royal Dwarf is defined by flavours of sweet citrus.

Royal Dwarf is fast to grow, and will be ready to harvest around 8–9 weeks after germination has taken place. Indoor plants will rarely exceed 70cm in height, producing yields up to 200g/m². When cultivated outdoors, Royal Dwarf achieves heights of 90cm and yields up to 80g per plant.
