Autoflowering Cannabis Seeds

autoflowering cannabis seeds image

Autoflowering cannabis seeds (also known as automatic seeds) have come a long way in the marijuana breeding world in recent years. This is because they mature and produce THC coated buds even under a regime of continuous light such as exists at very high latitudes at the height of summer, which makes them very popular for outdoor growers who are then able to harvest mature plants before the temperatures start to drop too low at the end of summer and early autumn. Auto seeds were originally produced and popularised by the Joint Doctor under the Lowryder brand name. Since that time the cross-breeding of famous cannabis strains with ruderalis genetics by other seed banks has resulted in an explosive proliferation of the number of such fast-maturing non-photo period dependent dwarf strains. Some seed banks such as Grass-O-Matic and Flash Seeds specialise in breeding and selling only such strains while long established seed banks such as Dutch Passion and Green House Seed Co., among many others, have also added auto strains to their catalogue.

An even more recent development has seen the appearance of high CBD (cannabidiol) autoflowering lines which have been developed for the increasingly important and accepted medical marijuana sector. With the help of the CBD Crew in Spain Grass-O-Matic has produced MED GOM 1.0, and Barney's Farm, Dinafem, Flash Seeds and Dutch Passion also include similar plants in their selection. What at first seemed like an interesting curiosity in the world of cannabis breeding and growing has turned into a dynamic growth sector due to its great popularity with customers who now have a huge choice of easy to grow small plants thanks to the continual experimentation and development of the seed banks.

Advantages of Automatic Seeds

Automatic marijuana seeds offer several advantages for the grower:

  • Ruderalis Genetics: Incorporating ruderalis genetic material enables the plants to begin the flowering stage independently of any shortening of (day) light hours. Indoors the light cycle needs to be reduced to at least 12 hours per 24 usually in order to induce the flowering phase. Outdoors the profound shortening of daylight hours needs to occur with most standard strains before any meaningful florescence is instigated resulting in the possibilty of severely compromised harvests due to inclement weather in all but the most reliable of climates or the hardiest of cannabis strains.
  • Fast Maturation: The average maturation time from seed to harvest falls in the range of 8 - 9 weeks, with some being even quicker, for most auto-flowering strains marking a considerable improvement over the majority of standard (non ruderalis-based) cannabis plants. The lack of any appreciable period of vegetative growth means that such seeds sprout, grow the first couple of sets of leaves and then go more or less straight into the flowering stage. This fast maturation enables more than one such crop to be successfully harvested outdoors in the same season. Of course indoors this has great benefits for the grower as well.
  • Small Compact Plants: The vast majority of these plants never exceed 60cm. in height which has clear advantages both for the indoor cultivator where space might be a consideration and outdoors where secrecy and prying eyes are also factors. Indoors a further advantage in the smaller size of these plants is that it is more feasible to use compact fluorescent lighting or even LED (light emitting diode) solutions which have reduced light penetration. This no longer need be a problem with the compact automatic strains.
