There are three different types of seeds—regular, feminized, and autoflower seeds. They all serve a different purpose, and all have pros and cons.
Autoflower seeds are unique and provide many benefits for growers. We’ll take a closer look at these advantages now in our autoflower seeds review.
You’ll learn how they’re made, how to germinate them, find out the best seeds to cultivate, and where to get them.
What are autoflower seeds?
What are autoflower seeds? The clue is in its name; the term refers to their behavior during the growth process. They’re cannabis seeds that grow into plants that start to blossom when they mature.
Unlike photoperiod strains, these crops don’t depend on light cycle changes to trigger their transition from the vegetative stage into bud-production mode.
Plants from autoflower seeds also undergo a shorter growth period, some being ready for harvest between 7–10 weeks after germination. This benefit allows breeders to cross photoperiod cultivars with ruderalis to achieve faster yields.
The height of autoflower crops typically ranges from 24–39 inches, making them perfect for discreet cultivation. They’re ideal for indoor growing as they don’t take up much vertical space.
Autoflower seeds also produce plants that are resistant to pests and diseases. Solving this problem helps beginners cultivate these seeds.
Autoflower seeds come in regular and feminized forms. Let’s compare the two other variants now:
Regular seeds vs. autoflower
Regular seeds are those you get from nature without human manipulation. There are male and female chromosomes within every pod, meaning you have an almost equal chance of getting plants of each gender.
When you cultivate regular autoflower cannabis seeds, the female crops begin flowering when they reach maturity. The males produce pollen sacs that fertilize the female bud and form seeds. This pollination process is why breeders prefer regular seeds.
Cultivators who only want delicious smokeable nugs have to identify and remove the male plants. The hassle of this segregation practice spurred breeders to introduce feminized seeds. Combining these seeds with autoflower seeds made it ideal for those wanting multiple harvests per year.
Feminized seeds vs. autoflowering
With feminized cannabis seeds, you don’t have the hassle of removing the male plants from the rest of the crop. You get all-females, which produce buds. No pesky pollinators take up growing space, so you maximize the yield from your efforts.
When using feminized autoflower seeds, you don’t have to change the light schedule to induce your plants to flower. It’s a natural growth process that doesn’t need human participation until harvest time.
How are autoflower seeds made?
To learn how to make autoflower seeds, you need to know about a third cannabis subspecies besides the two main ones—indica and sativa. It’s called ruderalis, which many believe is from Siberia, and now parts of Central/Eastern Europe and Asia.
To adapt to the harsh environment and survive, the ruderalis blooms and reproduces without adhering to any light cycle.
Breeders create autoflower marijuana seeds by crossing the ruderalis with indica and sativa cultivars. The resulting hybrids possess autoflowering ability but with bigger yields of quality buds than from growing ruderalis on its own.
How to germinate autoflower cannabis seeds
Growing marijuana successfully requires doing more than sticking seeds into the soil.
Learning how to germinate autoflower seeds is vital to increase your odds of getting healthy plants and bountiful yields.
Germination is the initial growth stage when seeds sprout roots. It’s a simple process that requires the following elements:
- Minimal handling – reduces the risk of damaging the delicate roots
- Adequate moisture – seeds need water to germinate
- Warm temperatures (70–77°F)
What’s the best way to germinate autoflower seeds? There are several methods. All of them have their merits, so it’s a matter of preference.
Some seed banks offer seed replacement guarantees, but you have to follow their germination protocol to qualify.
Here are ways growers germinate autoflower cannabis seeds. Try them out and see which one works best for you.
Planting in the soil
Cultivators favor planting autoflower seeds directly in soil for two reasons:
- It’s how cannabis plants grow in nature
- There’s no need to handle the seeds after you plant them
When germinating autoflower seeds in the soil, use a seed starter or potting soil as they have nutrients and beneficial microbes suitable for marijuana seedlings. Ensure that its pH is about 6.
As the grow medium already has what your seedlings need, don’t add fertilizer for at least two weeks. Excess nutrients can cause “nute burn,” which can damage your seedlings.
Autoflower seeds will develop stems within 4–7 days. During this time, keep your soil moist. When your plants are about four inches tall, transplant them into bigger pots.
Germinating in water
Growers can use this sprouting seed method at home with no equipment. You need a glass of plain water and your autoflower cannabis seeds.
Before adding the seeds, let the water rest until it reaches room temperature, about 65°F. Put in 2–3 seeds. It can take between 24–48 hours before the roots sprout. Keep the glass filled and maintain the temperature the whole time.
When your autoflower marijuana seeds have popped, transfer them to the soil. Exercise extreme care when handling the new roots because they’re very fragile.
Paper towel method
Here’s another method that only requires common household items, such as paper towels, a clean plate, bottled water, tweezers, and your autoflower seeds. As hygiene is important, be sure to prepare a sterilized workspace for the purpose.
The steps are straightforward. Start by dampening two paper towels. Use a spray bottle, so you don’t soak them. Your seeds need moisture, not excessive water.
Lay one paper towel on your plate. Gently place your autoflower cannabis seeds on it using the tweezers. A general rule of thumb is to spread them about an inch apart. When you finish, cover the seeds with the other towel.
Set your plate somewhere warm and dark, like in a drawer or cupboard. It takes about 1–5 days before the roots start to sprout, so be sure to check on your autoflower marijuana seeds every 24 hours.
Use tweezers to remove popped seeds and plant them in the soil. Ensure that the paper towels remain moist. Wet them regularly, so they don’t dry out. Repeat the process every day until all your autoflower seeds have taproots.
Germinating in peat pellets
Another way of germinating autoflower seeds to avoid damaging young roots is to plant the seeds in peat pellets. Soak the pellets in warm water until they expand before using them.
Peat is ideal for marijuana germination as it has a 5.5 pH level and all the nutrients your autoflower marijuana seeds need. These are partly decayed organic matter in compressed form, which provides nutrition for seedlings.
When the seeds pop, the roots will appear out of the peat. Transplant the entire pellet into the soil, where it’ll continue to grow.
How to grow autoflower seeds
After germinating the autoflower cannabis seeds and they sprout roots, place them into the soil. Handle them very carefully as they’re fragile at this stage. Many growers prefer to germinate in the soil to avoid moving the seedlings and damaging them.
While the Lowryder strain, which many cultivators consider the first autoflowering cultivar, was challenging to grow, autoflower seeds today are ideal for multiple harvests because:
- These cannabis plants begin to flower upon maturity, so there’s no need to monitor and adjust the light cycle
- Crops are resistant to mold and pests
Most marijuana plants require lots of nutrients during the seedling and vegetative, but those grown from autoflower seeds don’t need as much. You only need to give them 50–75% of the recommended dose. It’s essential not to overuse fertilizer as it can harm your plants.
Crops from autoflower seeds flourish in a warm climate with temperatures of 75 to 86°F. Their ruderalis traits allow them to adapt to hotter and colder weather, but the conditions may affect their yield.
While you can’t control the weather when growing outdoors, you can give your indoor plants the optimum environment they need to thrive. This is a key reason most growers prefer the latter method to cultivate autoflower seeds.
Another upside of indoor cultivation is the short stature of the plants keeps your growing activity discreet.
