THE UK’S BEST AUTOFLOWER SEEDS

The Advantages of Growing Autoflowering Seeds

Thanks to their Cannabis ruderalis heritage, autoflowering cannabis strains have adapted to harsh environments with long daylight hours. Modern breeding has taken these resilient genetics and supercharged them, creating autoflower strains that rival photoperiods in potency, flavor, and produce impressive yields. Whether you’re a beginner or a seasoned grower, autos offer efficiency and convenience.

• Fast Harvests: Most autos are ready in just 8-12 weeks from seed, making it possible to produce multiple harvests per year.
• Beginner-Friendly: Make cannabis cultivation easy with hardy genetics that require minimal maintenance.
• Compact Growth: Autos are small which makes them ideal for growers with limited space such as tents, balconies and closets.
• Pest & Mold Resistance: Their robust ruderalis genetics make them highly resilient to more resistant to cold weather, pests and other environmental stressors.
• No Light Schedule Hassle: Unlike photoperiod strains, autos flower regardless of light exposure, making them easy to cultivate indoors and outdoors.
• High-Quality Buds: Thanks to our cutting-edge breeding techniques, our autoflowering strains pack high THC levels and big yields.

Challenges you might face when growing autos

• Less Time for Recovery – Autos grow fast and don’t have time to bounce back from mistakes. Stick to low-stress training (LST) and avoid heavy pruning to keep them on track.
• Smaller Yields Compared to Photoperiods – Since autos stay compact, they naturally yield less per plant. However, you can maximize output by growing multiple plants or optimizing your lights, nutrients, and environment.
• Limited Cloning Potential – Autos don’t respond well to cloning since they flower on a set schedule. For a steady supply, stagger your grows or run multiple strains.
• Nutrient Sensitivity – Autos don’t need as much feeding as photoperiods and can be easily overfed. Start light with nutrients and increase gradually based on plant response as explained below.
• No Control Over Flowering Time – Since autos flip on their own, you can’t extend veg time for bigger plants. To counter this use larger pots (5 gallons or more) and focus on strong early growth to maximize size.

Choosing the right autoflower strains

Indica are typically shorter, bushier, and have a faster flowering time, making them ideal for small spaces and colder climates. They produce relaxing, body-heavy effects that are perfect for evening use. Sativas, on the other hand, tend to grow taller with a more open structure, taking slightly longer to mature. They deliver uplifting, energetic effects that are great for daytime consumption. While Indica strains are often preferred for their ease of cultivation and compact size, Sativas appeal to those looking for a cerebral, creativity-boosting high.

What Yield Can I Expect?

Autoflower yields depend on genetics, grow conditions, and grower expertise. On average:

• Indoor yields: 28-120g per plant (influenced by pot size and light intensity).
• Outdoor yields: Generally higher due to unrestricted root growth in the ground.

For maximum results, consider high-yielding strains like Auto Pounder, bred for massive harvests.

How To Germinate Autoflower Seeds

Give your seeds the best start by trying this simple and beginner friendly germination method:

1. Place a damp paper towel on a plate.
2. Spread seeds about an inch apart.
3. Cover with another damp paper towel and a second plate.
4. Store in a warm, dark place (21-26°C, 60-70% humidity).
5. Check daily, ensuring the towel remains moist. In 72 hours, taproots should appear.
6. Once sprouted, carefully transfer the plants to their final containers.

How to Plant Autoflower Seeds After Germination

Choosing the Right Pot:

• Indoors: 3-5 gallon (11-19L) pots.
• Outdoors: 5-10 gallon (20-40L) pots for optimal root development.

Ideal Soil Mix:

• Perlite – Enhances aeration and drainage.
• Coco Coir – Helps with moisture retention.
• Peat Moss – Retains water while gradually releasing nutrients.

Planting Steps:

1. Create a 1-inch hole.
2. Place the seed taproot-down.
3. Cover gently with soil.

Perfecting Autoflower Soil

For the best results with autoflower seeds, use a light, well-aerated potting soil that retains moisture without becoming waterlogged. A mix of peat moss, perlite, and compost works well, providing the right balance of drainage and nutrients. Autos thrive in slightly acidic soil (pH 6.0-6.5) with a mild nutrient load—too much can stunt growth. Avoid heavy soils that compact easily, as they restrict root development and slow down your plant’s progress.

How to Care for Autoflower Seedlings

Watering Guidelines:

• Days 1-4: Light misting to keep soil moist.
• Days 5-10: Water around the plants, avoiding overwatering.
• General Rule: Only water when the top inch of soil feels dry.

Early Growth Tips:

• Minimal handling – Seedlings are delicate, avoid unnecessary stress.
• Airflow – A light fan helps strengthen stems but avoid strong wind.
• No nutrients yet – Wait until day 10-14 before feeding.

Light Cycles for Autoflower Plants

Unlike photoperiod strains, autos will start flowering regardless of light cycle, here is a guide to how best to optimize your light schedules.

• 18/6 (18 hours light / 6 hours dark): The go-to choice for balancing growth and energy efficiency.
• 20/4 (20 hours light / 4 hours dark): Slightly faster growth while allowing some recovery time.
• 24/0 (24 hours light / 0 hours dark): Maximizes photosynthesis but can increase stress if not managed correctly.

5 Key Tips to Increase Yield

1. Maximize Light Exposure – Use full-spectrum LEDs (600-900 µmol/m²/s) and position lights correctly.
2. Utilize Low-Stress Training (LST) – Gently bending branches boosts light penetration without stunting growth.
3. Feed Properly – Start with diluted nutrients (10-7-5 NPK in veg, 5-10-10 in flower) and avoid overfeeding.
4. Optimize Root Health – Use fabric pots with well-aerated soil to prevent overwatering and root rot.
5. Maintain Ideal Climate – Keep temps at 21-27°C and humidity at 60-70% (veg) and 40-50% (flower).

What Nutrients Do Autoflowers Need?

Autoflowers require a lighter feeding regimen than normal feminized seeds. Here’s an adjusted nutrient schedule:

• Week 1 (Seedling Stage): Use only pH-balanced water, no nutrients needed.
• Week 2 (Late Seedling Stage): Start with a mild 2-1-2 NPK feed at 1/8 strength.
• Weeks 3-4 (Vegetative Period): Increase to a 10-5-5 NPK feed at 1/4 to 1/2 strength.
• Weeks 5-6 (Early Flowering): Switch to a 5-10-10 NPK feed at 1/2 strength.
• Weeks 7-9 (Full Flowering): Maintain a 5-15-10 NPK feed at 1/2 strength.
• Week 10 (Pre-Harvest Flush): Use only pH-balanced water to flush out excess nutrients before harvest.

When to Harvest Autoflower Cannabis Plants

Harvesting at the right time maximizes potency and flavor. Check trichome color with a jeweler’s loupe:

• Clear trichomes: Too early – buds lack potency.
• Milky/cloudy trichomes: Peak THC – best for an intense, euphoric high.
• Amber trichomes: More sedative effects – great for relaxation and pain relief.

Harvesting Steps:

• Cut at the base and hang upside down in a cool, dark space (18°C, 45% humidity).
• Dry: 10-14 days until the buds feel crisp on the outside.
• Cure: Store in glass jars, burping daily for two weeks, then weekly for 1-2 months.
