Planting Autoflower Seeds Directly in Soil

Looking for a hassle-free way to grow your own cannabis plants? Planting autoflower seeds directly in soil might be the perfect solution for you. With this method, you can skip the time-consuming and tricky process of germinating your seeds separately, and instead, let them sprout right in the ground. In this article, we’ll walk you through the steps of planting autoflower seeds directly in soil, from selecting the right strain to ensuring optimal growing conditions. So, let’s get started!

Planting Autoflower Seeds Directly in Soil:

Growing cannabis can be a fun and rewarding hobby, but it can also be intimidating for beginners. One of the easiest and most convenient ways to start your own cannabis garden is by planting autoflower seeds directly in soil. This method eliminates the need for complex germination techniques and allows your plants to grow naturally. In this guide, we’ll cover everything you need to know to successfully grow cannabis using this technique.

Germinating Autoflower Seeds Directly in Soil

The first step to growing cannabis plants directly in soil is to select high-quality autoflower seeds. You can buy them online or at a local dispensary. Once you have your seeds, you’ll need to prepare your soil by making sure it’s loose and well-draining. You can also use a soil mix that’s specifically designed for cannabis growing.


To germinate your seeds directly in soil, follow these steps:

  1. Moisten the soil with water, but make sure it’s not too wet.
  2. Create small holes in the soil with a pencil or your finger, about 1/4 inch deep.
  3. Place the seed in the hole and gently cover it with soil.
  4. Water the soil around the seed, but be careful not to overwater.
  5. Place a humidity dome or plastic wrap over the top of the container to keep moisture in.
  6. Wait for the seed to germinate and sprout, which can take anywhere from 2 to 10 days depending on the strain.

Soil Structure for Autoflower Plants


The structure of your soil is crucial for the health and growth of your cannabis plants. Good soil structure allows for proper water drainage, nutrient uptake, and oxygen flow. Here are some tips to help you create the perfect soil structure:

  1. Use a high-quality soil mix that’s rich in nutrients and organic matter.
  2. Add perlite, vermiculite, or coco coir to improve drainage and aeration.
  3. Use compost, worm castings, or other organic fertilizers to enrich the soil.
  4. Test the pH of your soil and adjust it if necessary to a range of 6.0 to 7.0.

Making Your Own Soil Mix for Autoflower Plants

If you prefer to make your own soil mix, here’s a simple recipe to get you started:

  • 2 parts high-quality potting soil
  • 1 part perlite or vermiculite
  • 1 part coco coir
  • 1/2 part compost or worm castings
  • 1/2 part organic fertilizers such as bat guano, blood meal, or bone meal

Mix all the ingredients together thoroughly, and adjust the pH as needed. This soil mix provides good drainage, aeration, and nutrition for your cannabis plants.

Watering Autoflower Plants Properly

Proper watering is essential for the health and growth of your cannabis plants. Here are some tips to help you water your autoflower plants correctly:

  1. Water your plants when the soil is dry to the touch, but not completely dry.
  2. Water slowly and evenly, making sure the soil is thoroughly moistened.
  3. Avoid overwatering, which can lead to root rot and other problems.
  4. Use a pH meter to test the pH of your water, and adjust it if necessary to a range of 6.0 to 7.0.

Lighting Requirements for Autoflower Plants

Growing autoflower plants requires attention to their unique lighting needs. While autoflower plants can grow under almost any type of light, providing the right spectrum and intensity can significantly improve their growth and yield. Here are some tips to help you provide the optimal lighting for your autoflower plants:

  • Provide a full-spectrum light that includes both blue and red wavelengths. Autoflower plants require a different light spectrum than photoperiod plants. They perform best under a full-spectrum light that includes both blue and red wavelengths. Blue light promotes vegetative growth, while red light stimulates flowering. You can achieve a full spectrum with either LED grow lights or High-Intensity Discharge (HID) lamps.
  • Maintain a consistent light schedule of 18-24 hours of light per day throughout the entire growth cycle. Unlike photoperiod plants, autoflower plants do not require a change in light cycle to initiate flowering. Providing consistent light of 18-24 hours per day throughout the entire growth cycle will ensure maximum growth and yield.
  • Consider using LED grow lights or High-Intensity Discharge (HID) lamps for a full spectrum and maximum efficiency. LED grow lights and HID lamps are efficient and provide a full spectrum of light that is ideal for autoflower plants.

Training Techniques for Autoflower Plants

Training autoflower plants can be challenging due to their short vegetative period, but there are still techniques that can be used to improve yields and manage plant size. In this section, we’ll cover the following topics:

  • Low-stress training techniques for autoflower plants, such as LST (Low-Stress Training) and SCROG (Screen of Green). LST involves bending the plant’s stems to promote an even canopy, while SCROG involves using a screen to support the plant’s growth.
  • Defoliation methods for improving light penetration and airflow. Defoliation involves removing the plant’s leaves to promote better airflow and light penetration.
  • Other methods for improving yields and managing plant size, such as supercropping and selective pruning. Supercropping involves intentionally damaging the plant’s stem to promote lateral growth, while selective pruning involves removing specific parts of the plant to improve its structure.

Pest and Disease Management

Preventing and managing pests and diseases is crucial for a successful autoflower harvest. Here are some common pests and diseases that can affect autoflower plants and some tips on how to prevent and manage them:

Common Pests and Diseases

  • Spider Mites: These tiny pests can cause yellowing leaves, stunted growth, and webbing on the plants. To prevent and manage spider mites, make sure to maintain proper humidity levels and use predatory insects like ladybugs and lacewings to control their population.
  • Thrips: These pests feed on the sap of plants, causing deformed leaves and stunted growth. To prevent and manage thrips, make sure to regularly inspect your plants for signs of infestation and use organic insecticidal soaps or neem oil to control their population.
  • Powdery Mildew: This fungus can cause white powdery spots on the leaves and stems of the plants. To prevent and manage powdery mildew, make sure to maintain proper airflow and humidity levels in your growing environment, and use organic fungicides like sulfur or copper soap.


Growing cannabis plants directly in soil can be a fun and easy way to start your own garden. By following the tips and techniques outlined in this guide, you can successfully grow healthy and vigorous autoflower plants that produce high-quality buds. Remember to choose high-quality autoflower seeds, create a well-structured soil mix, water your plants properly, and give them the right amount of light and nutrients. With patience and care, you can enjoy a bountiful harvest of your own homegrown cannabis. Happy growing!
