This essential characteristic evolved as a necessity for survival in the harsh, inhospitable areas of central Russia where Cannabis Ruderalis, the original autoflowering strain that bred this almost magical ability, originated. Lacking the longer, warmer summers of the Indian continent or the tropical and equatorial zones where (respectively) Indica and Sativa evolved, their relative did not have the luxury of being able to wait for the change in light cycles that signal the beginning of summer to start flowering – the weather would become cold enough to kill the plants before pollination and seeding could take place. Instead, it had to begin flowering as soon as it was old enough in order to have enough time to complete the reproductive cycle and make new seeds. Breeders immediately saw the advantage of this for other strains, and began breeding seeds with this ability to ‘auto flower’.
In terms of turnover, these seeds are capable of producing reasonably sized yields even with a less intense light source. However, the general rule that the greater the light intensity, the better the results, holds true here too. It should also be remembered that how much these types will give is governed by the final size of the plant – a windowsill crop of virtually dwarf cannabis is never going to produce as much as it would in large pots under high-intensity light. In general, however, the amount of bud eventually gleaned from seeds in this section is favourably comparable with that of regular or feminized seeds from the same variety.
Yield factors for autoflowering seed strains
How is cannabis able to flower automatically?
Ideal for beginners
Autoflowering seeds, on the other hand, are able to complete their life cycle regardless of how long the days are, although at least eighteen hours of light will give the best results. Unlike regular seeds, ‘auto’ seeds grow crops that do not need to undergo the usual cycle of 12 hours of light alternating with 12 hours of darkness in order to bloom successfully, whether they are indica, sativa or hybrid. They seem virtually immune to light pollution, tolerating irregular and unpredictable periods of light and darkness with impunity. Outdoor gardeners with short summers can wait until the warmest weeks to cultivate their automatic cannabis seed crop, safe in the knowledge that most of these hours will fuel the flower production, not the vegetation, period.
In addition, these strains are a great choice for gardeners in less warm climate areas who wish to grow on open ground, or on a balcony or window ledge, but find themselves restricted by short summers.
Additionally, the smaller size of the plants suits a grower who has limited toom. And they’re easier to look after. An Autoflower cannabis plant hardly grows over four foot tall, which makes the harvesters job of caring, trimming and training an easier task throughout each stage of the grow cycle.
An Autoflower does not rely on the same amount of light to reach flowering. This means that you can stagger your outdoor grows to harvest multiple times a year.
Autoflower cannabis seeds are a Seedsman speciality. In fact, we were the first seed bank in the world to sell Autoflower cannabis seeds.
Due to their genetic composition, Autoflowering plants are usually smaller than other regular seed cannabis plants. When you compare an Autoflower grow to photoperiod feminised cannabis plants, they’re better at surviving pests and mould.
Autoflowers are also perfect for beginner growers due to their less demanding harvest cycle. Regular strains need constant monitoring and adjusting of the lighting to ensure the plants get their full 12 hours. If you get this wrong, it can lead a plant going back to a vegetative phase which means a ruined plant. Autoflowers mean no worrying about constant lighting. Plus, they grow faster, for those of us who are impatient!
Autoflowering cannabis seeds are seeds that automatically shift from vegetative growth to flowering stages with age rather than the systematic ratio of light exposure. Most ‘autos’ will be ready to harvest in less than 10 weeks from seed.
Here at Seedsman, we have an extensive library of autoflowering seeds for our customers to choose from, including collections from established breeders Sweet Seeds, Dinafem Seeds, Royal Queen Seeds, and Flash exclusively produce autoflowering seeds.
2. Use 20 hours of daily light from seed to harvest
Auto Skywalker Haze®
Most people want the best THC-rich autoflower seeds for their next grow. This is perhaps Dutch Passion’s greatest area of strength, with several exceptionally strong autoflower varieties. THC levels of over 20% are quite possible from a well grown auto. If your goal is to grow auto seeds and harvest the strongest possible buds then you have come to the right seed bank. As well as extreme THC levels you will find Dutch Passion auto seeds easy to grow with heavy yields as standard.
Autoflower seeds work on a finite life span, so it’s important to keep conditions as settled as possible so the auto can make full use of the 11 week growing time. Many people germinate the seeds and then place the seedling in the final growing container. This minimises further disruption to the plant. If you are pre-growing them in smaller pots we recommend a maximum time of 2.5 – 3 weeks before transplanting them to their final container or outdoor growing spot.
