An autoflowering cannabis strain switches from the vegetative stage to the flowering stage automatically instead of requiring closely timed hours of light and dark. Photoperiod flowering seeds start to bloom after the summer solstice, while autoflowering seeds flower after a specific phase of the development period. In other words, they grow automatically (hence their name, “autoflowering”) when they reach the right size.
Autoflowering seeds are typically a mixture of cannabis sativa or indica with cannabis ruderalis, a species native to Russia . People don’t grow cannabis ruderalis on its own because it typically lacks a high degree of THC content. But because this species grows automatically after seven weeks and fares well in cold weather, these traits have made them desirable to use for interbreeding.
Pros and Cons of Autoflowering Seeds
Autoflowering cannabis seeds combine the genetics of sativa, indica (or hybrids of them) with cannabis ruderalis. Cannabis ruderalis is a variety very few people know about because it is naturally smaller, with smaller buds that produce very little to no THC.
If you live in an area where the climate can change rather quickly, or you aren’t too particular about maintaining the ideal growing conditions for cannabis, then opt for autoflowering strains since these are more forgiving when conditions aren’t exactly right.
With autoflowering seeds, you can grow compact cannabis plants in an inconspicuous part of your property without anyone asking what you are growing. Plus, their rapid growth makes it even less likely for visitors to notice them. Regular cannabis plants take a lot longer to reach full maturity, which only increases the chance that people will notice your plants. Since some autoflowering cannabis strains can mature in as few as 8 or 9 weeks, the amount of time that it takes to reach harvest is a definite pro on the pros and cons of autoflowering seeds list.
Renowned for their sweet berry notes is the famous “Blue” family of cannabis. Originally from the US West Coast, Blueberry has been infused into two popular RQS offerings: Haze Berry Auto combines Haze Berry and Blueberry Auto, while Bluematic is the automatic variant of the original Blueberry.
Keep your grow room’s temp at a moderate 21°C (room temperature) for healthy growth. Colder temperatures or excessive heat can lead to growing problems. For best results, grow in an environment where you can maintain full control. Use heating and/or cooling if necessary.
Purple (Purple Queen Auto, Purplematic)
From the West Coast of the US hails the immensely popular Cookies family of strains—famous not just for their sweet dessert flavours, but also their uplifting and social effect. Some of the best autoflowers with Cookies genetics are Royal Queen Seeds’ Gorilla Auto (based on the ultra-potent Gorilla Glue) and Cookies Auto.
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.
For autoflowers, you want soil that is even lighter than that used to grow feminized photoperiod cannabis plants. If needed, amend your soil with perlite to increase airiness and drainage.
These more traditional strains naturally produce flowers during the late summer, fall, or in some regions, into winter, so the amount of light and dark they receive should reflect the changing season and shortening of days. Most growers trigger the flowering process in photoperiod marijuana plants by shortening their light cycles to an even 12 hours of light and 12 hours of dark each day.
Cannabis ruderalis is a subspecies of cannabis plant first identified in the 1920’s. It’s naturally shorter in stature, contains a lower concentration of tetrahydrocannabinol (THC), and has autoflowering attributes.
Differences Between Autoflowering and Photoperiod Marijuana Strains
As a descendent of nearly entirely sativa, the Amnesia Haze Automatic strain contains high levels of THC and therefore requires a slightly longer flowering period. The flavor and aroma of this strain is described as sweet, spicy, or musky.
Marijuana strains are classified as autoflowering when they aren’t reliant on light cycles to flower. Here we dive into autoflowering strains, the advantages autoflowering offers growers, and whether the characteristics of autoflowering strains meet your needs.
The flowers of most autoflowering plants are ready to be harvested 2 to 3 months after they’ve sprouted from seed. This is because the vegetative stage of autoflowering plants is shorter, lasting for just a few weeks.
