10 Tips for Successful Outdoor Cultivation of Automatic Seeds

Automatic seeds offer a flexible cultivation method as they flower independently of daylight hours, allowing for multiple harvests per year. Here are ten essential tips to get the most out of your outdoor grow.

Our 10 Tips for Your Success

1. Choosing the Right Strain

Selecting the right strain is crucial for the success of your outdoor grow. Automatic seeds vary in flowering times, growth height, and resistance to environmental factors. Choose robust, disease-resistant strains suited to your climate. In humid regions, mold-resistant strains are beneficial, while heat-tolerant strains thrive in hot climates. A mix of strains with different flowering times (70 to 100 days) can help ensure a continuous harvest. Additionally, consider the desired effects—some automatic seeds are more calming, while others are stimulating.

2. Selecting an Optimal Sunlight Location

Light is the most important factor for plant growth. A site facing south or southeast ensures maximum light exposure throughout the day. Ensure that trees or buildings do not cast shadows on your plants. The more direct sunlight your plants receive, the stronger they will grow and the higher the yield will be. If your location lacks sufficient sunlight, you can use reflective materials (such as white walls or foil) to enhance light exposure. In very hot climates, slight shading during midday can prevent overheating.

3. Germination in a Protected Environment

Young plants are particularly sensitive to temperature fluctuations, pests, and strong sunlight. Therefore, it is recommended to germinate seeds in a protected environment, such as a windowsill or small greenhouse. Use high-quality seed-starting soil to optimize root development. Once seedlings are 5-10 cm tall and have multiple leaves, they can be transplanted outdoors. Gradually acclimate them to direct sunlight to prevent sunburn.

4. Sea of Green Method for Maximum Yield

The Sea of Green (SOG) method is an efficient technique for maximizing yield in small spaces. It involves placing many plants close together to form a dense, uniform canopy. This helps protect against wind and pests while maximizing light exposure. The advantage is a faster and more even flowering phase. Ensure plants do not grow too large to avoid light competition. This method is particularly suitable for automatic seeds as they remain compact.

5. Using Companion Plants for Camouflage and Pest Control

Companion plants provide multiple benefits: they camouflage your grow, deter pests, and improve soil quality. Mint, basil, and chamomile help repel pests, while sunflowers and lavender attract beneficial insects that prey on pests. Additionally, white clover can help enrich the soil with nitrogen. Mixing with other plants makes your garden look more natural and less conspicuous.

6. Protecting Seedlings

Young plants are vulnerable to snails, rodents, and insects. To protect them, use clear plastic domes that act as mini greenhouses and provide protection. Alternatively, copper tape or slug barriers can help keep snails away. If rodents are a problem, use fine mesh wire around plants. Regularly check for damage and act early if issues arise.

7. Large Pots for Optimal Growth

Automatic seeds prefer stable conditions and are sensitive to transplanting. Use sufficiently large pots (20-25 liters) from the start to avoid growth restrictions. Fabric pots are ideal as they promote better root aeration and reduce the risk of waterlogging. Use high-quality soil with good drainage to prevent root rot. A mix of coconut fiber, worm castings, and perlite ensures optimal conditions.

8. Adjusted Fertilization for Optimal Growth

Automatic seeds have a short vegetative period, making proper fertilization essential. During the first three weeks, they require nitrogen for growth, followed by higher levels of phosphorus and potassium for flowering. Use organic fertilizers such as worm castings, compost tea, or bat guano to provide natural nutrients. Over-fertilization can be harmful, so start with low doses and gradually increase.

9. Planning Multiple Harvests per Year

In mild climates, automatic seeds can be harvested multiple times per year. In Southern Europe, California, or South America, up to four harvests annually are possible. The first sowing can take place in March, while the last harvest is often possible in November. To have a continuous supply of fresh plants, stagger planting times. Planning with different strains can further optimize harvest periods.

10. Protection from Weather and Curious Eyes

A simple polytunnel can protect your plants from wind, heavy rain, and cold temperatures. These structures, usually made of plastic sheeting, are easy to build. They help stabilize the microclimate and prevent heavy rain from damaging plants. Additionally, a polytunnel can keep your grow discreet and shielded from prying eyes.

With these detailed tips, you are well-prepared to cultivate healthy and high-yielding automatic seeds outdoors. Best of luck with your harvest!
