Want to grow your own cannabis quickly and without the hassle? At Novus Fumus, you’ll find the best autoflower seeds from top brands like Vision Seeds, Royal Queen Seeds (RQS), and Dutch Passion. Autoflowering seeds are the ideal choice for growers who value convenience: they bloom automatically and are ready for harvest in record time. When you order from us, you can count on years of expertise and lightning-fast shipping.
What are autoflower seeds?
Autoflower seeds are cannabis seeds that start blooming automatically once the plant reaches a certain age (usually after 2 to 4 weeks), regardless of the number of light hours they receive. Unlike traditional (photoperiod) strains, you don’t need to adjust the light schedule to trigger the flowering phase. This makes them perfect for beginners and growers looking to harvest multiple times in a single season.
Most autoflowers today are feminized. This means you are virtually 100% certain to get female plants, which produce the desired buds full of terpenes and resin. You won’t waste any time dealing with male plants.
Advantages of autoflower seeds
Choosing autoflowering cannabis seeds offers several major benefits for your grow project:
Fast harvest: Often ready from seed to bud within 8 to 12 weeks.
Ease of use: No stress over light schedules; they bloom on their own.
Compact size: Ideal for a discreet corner on your balcony or a small grow space.
High resistance: Thanks to Ruderalis genetics, they are often more resistant to cold and pests.
Multiple harvests: Due to their short cycle, you can often harvest twice per summer when growing outdoors.
What are the disadvantages of autoflowering seeds?
While they are incredibly convenient, there are a few things to keep in mind. The biggest drawback is the yield per plant; because the plants stay small, you harvest less volume than you would from large photoperiod plants. On average, the outdoor yield ranges between 79 and 179 grams per plant. Additionally, due to their short life cycle, they have very little time to recover from any growing mistakes.
At Novus Fumus, we’ve gathered the "Big Three" for you. Each brand has its own character, but they all have one thing in common: they deliver genetics you can rely on. Check below to see which brand best fits your growing style.
Vision Seeds: Stable and affordable
Are you looking for seeds that simply do what they promise without breaking the bank? Go for Vision Seeds. These guys are known for their reliable genetics and no-nonsense approach. They are ideal for the grower who wants a stable harvest for an honest price. We highly recommend their Vision Gelato Auto; it gives you that delicious, full flavor without a complicated growing process.
Royal Queen Seeds (RQS): The innovators
Do you want the latest techniques and the most powerful strains? Then Royal Queen Seeds is the place to be. RQS is one of the biggest players in Europe, and for good reason. They constantly develop their seeds for the perfect balance between potency and ease of growth. Their Royal Gorilla Automatic is an absolute favorite in our shop; a fast grower with an effect that will blow you away.
For those who love tradition and pure homegrown quality, there is Dutch Passion. This brand has been around since the '80s and they practically invented feminized seeds. They focus on high-quality genetics and unique terpene profiles. Their Auto Mazar is a legend in the cannabis world and remains one of the most popular choices for growers aiming for top-tier results.
Buying autoflower seeds: What should you look for?

Location: Check if the strain is suitable for your climate—outdoors, indoors, or in a greenhouse.
Terpene profile: Look at the scent and flavor descriptions for the best experience.
Grow Guide: How to get the most out of your autoflower seeds
Because autoflowers have a fixed life cycle of about 8 to 12 weeks, every day counts. They have less time to recover than normal plants, so a good start is half the battle. Whether you have a professional tent or a sunny spot on the windowsill, these tips from Novus Fumus will help you maximize your genetics.
What is the best way to germinate cannabis seeds?
A strong start is crucial. Wondering which method suits you best? Check out the 3 effective options on our page: Germinating cannabis seeds.
Growing indoors without a tent (The Windowsill)
Don't have space for a tent or expensive lights? No problem, you can do just fine on a bright windowsill. It’s the most natural way to grow indoors, but keep these points in mind:
Choose the right side: Your plant needs tons of light. A south-facing window is practically a requirement. On the north or east side, the plant often gets too little energy, causing it to become "stretchy" and weak.
Watch out for drafts and cold: Glass can become ice-cold at night. Move your pot slightly away from the window in the evening to prevent a cold shock. A constant temperature between 20°C and 25°C is perfect for healthy growth.
Light pollution is not an issue: The great thing about autoflowers on the windowsill is that they don’t get confused by living room lamps or streetlights. They follow their own internal clock and keep blooming regardless.
Growing indoors in a tent or grow box
In a controlled environment, you have all the controls in your hands. Just use a good full-spectrum LED lamp; this provides a nice balance between growth and bloom without turning your tent into an oven.
Light schedule: Most of our growers go for 18 hours of light and 6 hours of darkness (18/6). If you really want to push for a larger yield, 20 hours of light (20/4) also works excellently.
Air circulation: Place a small fan that blows gently over the tops. This makes the stems stronger and ensures that mold stands no chance by keeping the air moving between the leaves.
Growing outdoors in the garden or on the balcony
The sun is the most powerful light source available, but be smart with your timing. Don't start sowing outdoors until the night frost is truly gone, usually from mid-May (after the Ice Saints). The months of June and July provide the plant with the most energy.
Protection from rain: Especially in the final weeks of flowering, those thick buds soak up water like a sponge. Move your plants under a shelter if it rains for long periods to prevent bud rot.
Location: Place the pot in the sunniest spot you have. The more direct sunlight the plant catches, the more compact and flavorful the buds will become thanks to the development of terpenes.
The Technical Basics: Soil, Pots, and Climate
The right pot and soil: Use the final pot immediately, at least 11 to 15 liters. Autoflowers hate being repotted; this stops growth for a few days, and you don’t have that time to spare. Choose an airy "Light Mix" potting soil. If the soil is too compact, mix in some perlite so the roots can easily get oxygen.
Humidity and Temperature: In the beginning (the seedling phase), humidity should be high, around 70%. Once the plant starts growing, bring this down to 50%. During flowering, a lower humidity of 40% to 50% is essential to protect your harvest. Keep the daytime temperature around 23 degrees and no lower than 17 degrees at night for the best results.
Watering: Do this with care. Overly wet soil suffocates the roots. The soil should feel moist, but certainly not soaking wet. Check it simply by sticking your finger into the soil.
Expert Tip: Keep a close eye on the plant. When the tiny resin droplets (trichomes) turn cloudy white, you are close to harvest. At Novus Fumus, we always advise taking your time for drying; that brings out the best flavor from your homegrown buds.

Frequently Asked Questions about autoflower seeds
How long does it take from seed to harvest? Most autoflowers are fully ready for harvest within 8 to 12 weeks.
How deep should a cannabis seed be planted? Plant a (germinated) seed at 1 – 1.5 cm depth with the taproot facing down. Carefully handle the seed by the shell using tweezers or clean fingers; never touch the root. Lightly cover the hole and keep the soil evenly moist.
Why are my autoflowers so small? Small autoflowers are often the result of stress, over-fertilization, or overwatering. Because the growth phase of an autoflower is short and fixed, the plant has little time to recover from mistakes. A lack of nutrients or a pot that is too small can also stunt growth.
