Optimal humidity for your autoflowers depends on your plant’s age. In the first few weeks, they prefer a more humid environment. Reduce relative humidity to 40–50% when your plants start to flower to reduce the risk of mould.
Outdoors: You are not as beholden to the natural seasons as with photoperiod plants. You can plant your autos at any time of the year, provided there is no frost. Harvest 8–10 weeks after planting. If you plant your autoflowers several weeks apart, you can achieve several harvests per year! Autoflowers are stealthy and compact. This makes them perfect for low-key outdoor operations.
In contrast, autoflowering strains flower based on age, independent of light hours, which means they are non-photoperiod strains. Autoflowers have several noteworthy characteristics:
How much time do you need to grow autoflowers?
Autoflowering cannabis seeds produce plants that flower on their own after 2–4 weeks of growth. Growers don’t need to worry about switching the light schedule to initiate and maintain the flowering phase, like they would if growing feminized photoperiod cannabis.
When growing in soil, the optimal pH level of your water/nutrient solution is 6–7. You can adjust your water to the correct pH level using natural pH “up” or “down” products.
In general, autoflowers are smaller than feminized photoperiod cannabis. Smaller plants require less nutrients than large plants.
These days, autoflowers can satisfy even the most demanding of users: Recreational users won’t have difficulties finding automatic varieties rich in THC, and holistic users can get autoflowers low in THC but high in CBD to benefit from the non-psychoactive cannabinoid.
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!
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.
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.
Autoflower cannabis seeds are a Seedsman speciality. In fact, we were the first seed bank in the world to sell Autoflower cannabis seeds.
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.
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.
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.
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’.
This is the first group of varieties to produce superior bud featuring elevated cannabinoid levels without the need for intense light during set, consistent periods of time. Whether using artificial light or sunlight, care and attention was always required in matters of timing the plants’ exposure to it, and ensuring that the hours of darkness really were dark. Light pollution from even minor sources has been known to confuse their internal ‘clocks’ as to whether they are supposed to be vegetating or blooming.
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.
Feminized autoflowering cannabis seeds are easy to cultivate: They flower without the need to change light cycles or remove males. Automatic seeds are ideal for new growers, and for those who want a low-maintenance growing experience. Sensi Seeds’ sativas, indicas and hybrids (high THC or high CBD) are ideal for medicinal and recreational cannabis users alike.
