Selecting the Right Cannabis Strains

When choosing cannabis strains for your outdoor grow, consider the following factors:

Climate Adaptability

Different cannabis strains have varying degrees of adaptability to different climates. Some strains are better suited for warmer, sunnier environments, while others thrive in cooler, more temperate climates. Research and select strains that are known to perform well in your specific climate conditions.

Photoperiod or Auto-flowering

Cannabis plants can be photoperiod-dependent or Auto-flowering. Photoperiod-dependent strains require a specific light cycle (usually 12 hours of darkness and 12 hours of light) to initiate flowering. Auto-flowering strains, on the other hand, transition to the flowering stage automatically based on their age, regardless of light conditions. Consider your climate and the length of your growing season when choosing between these two types of strains.

Indica, Sativa, or Hybrid

Cannabis strains are typically classified as Indica, Sativa, or hybrid, based on their genetic characteristics. Indica strains tend to be shorter, bushier, and have a more sedating effect. Sativa strains are taller, with longer flowering times and a more energizing, cerebral high. Hybrids combine traits from both Indica and Sativa strains, offering a balanced experience. Consider your personal preferences and desired effects when selecting the right strain for your outdoor grow.

By choosing the right strains for your specific climate and preferences, you set yourself up for a successful and enjoyable outdoor cannabis grow.


Starting Your Seeds or Clones

Once you’ve selected your cannabis strains, you have two options for starting your plants: seeds or clones. Here’s what you need to know about each:


Starting your cannabis plants from seeds offers the advantage of genetic diversity and the potential for vigorous growth. When purchasing seeds, look for reputable seed banks or breeders that offer high-quality, feminized, or auto-flowering seeds. Feminized seeds ensure that your plants will be female, which is desirable for bud production. Auto-flowering seeds transition to the flowering stage automatically based on their age, making them suitable for growers with shorter growing seasons.


To start your seeds, follow these steps:

  1. Germination: Place your seeds in a damp paper towel or soak them in water until they crack open and a tiny taproot emerges.
  2. Planting: Transfer the germinated seeds to small pots or seedling trays filled with moist potting soil.
  3. Light and Temperature: Place the pots or trays under fluorescent lights or in a sunny location with temperatures between 70-85°F (20-30°C).
  4. Watering: Keep the soil consistently moist but not waterlogged. Water with care to avoid overwatering, which can lead to damping-off or root rot.
  5. Transplanting: Once your seedlings have developed several sets of leaves, they are ready to be transplanted into their final outdoor grow space.


Clones are cuttings taken from mature cannabis plants that have been rooted and ready for transplanting. Cloning allows you to replicate the exact genetic makeup of the mother plant, ensuring consistent traits and characteristics in your crop. Clones are typically purchased from reputable nurseries or obtained from fellow growers.


To successfully transplant clones, follow these steps:

  1. Preparation: Prepare small pots or containers filled with potting soil or a hydroponic medium.
  2. Rooting: Dip the cut end of the clone in a rooting hormone and gently insert it into the prepared potting soil or hydroponic medium.
  3. Light and Temperature: Place the clones under fluorescent lights or in a warm, sunny location with temperatures between 70-85°F (20-30°C).
  4. Watering: Keep the soil or hydroponic medium evenly moist, ensuring that the clones receive adequate hydration without becoming waterlogged.
  5. Transplanting: Once the clones have developed a healthy root system, they can be transplanted into their final outdoor grow space.

Whether you choose to start from seeds or clones, proper care and attention during the early stages will set the foundation for successful outdoor cannabis growth.


Transplanting Your Cannabis Plants

Transplanting your cannabis plants from their seedling stage to their final outdoor grow space is a crucial step in their development. Here’s how to ensure a smooth and successful transplant:


Choose the right time to transplant your cannabis plants based on the weather conditions and the maturity of your plants. Transplanting too early, when temperatures are still cool or there is a risk of frost, can stunt the growth of your plants. Wait until the threat of cold weather has passed and your plants have developed a healthy root system before transplanting.


Before transplanting, prepare your outdoor grow space by clearing the area of weeds, rocks, and debris. If you’re planting directly in the ground, loosen the soil and amend it with compost or organic matter as needed. If you’re using containers, fill them with high-quality potting soil or a well-draining growing medium.

Digging Holes

Dig holes in your outdoor grow space that are slightly larger than the root balls of your plants. Space the holes at least 2-3 feet apart to allow for proper airflow and growth. Gently remove the seedlings or clones from their pots, being careful not to damage the roots, and place them in the holes.


Place each plant in its respective hole, ensuring that the top of the root ball is level with the surrounding soil. Backfill the hole with soil, gently firming it around the plant to eliminate air pockets. Water thoroughly after transplanting to help settle the soil and provide hydration to the newly transplanted plants.

By following these steps, you can successfully transplant your cannabis plants and set them up for healthy growth in their outdoor environment.


Providing Adequate Water and Nutrients

Water and nutrients are essential for the healthy growth and development of your cannabis plants. Here’s how to ensure they receive adequate hydration and nourishment:

Watering Practices

Water your cannabis plants consistently, providing enough moisture to keep the soil evenly moist but not waterlogged. The frequency of watering will depend on factors such as temperature, humidity, and the size of your plants. As a general guideline, water your plants when the top inch of soil feels dry to the touch.

Avoid overwatering, as it can lead to root rot and other moisture-related issues. Ensure that your outdoor grow space has proper drainage to prevent waterlogging and root suffocation.

Nutrient Requirements for Potting Soil without Amendments

TDS and EC levels for cannabis plants at each week of vegetative growth, followed by the first few weeks of flowering:

12 (ripening/harvest)<1000 ppm<2.0 mS/cm

Cannabis plants have specific nutrient requirements at different stages of their growth cycle. During the vegetative stage, they require higher levels of nitrogen to promote leaf and stem growth. As they transition to the flowering stage, they require increased phosphorus and potassium to support bud development.

You can provide nutrients to your cannabis plants through organic amendments, such as compost or well-rotted manure, or through commercially available fertilizers specifically formulated for cannabis cultivation. Follow the instructions on the fertilizer packaging and monitor your plants for any signs of nutrient deficiencies or excesses.


Protecting Your Plants from Pests and Diseases

Outdoor cannabis plants are vulnerable to a variety of pests and diseases. Taking proactive measures to protect your plants will help ensure their health and productivity. Here are some strategies to consider:

Companion Planting

Companion planting involves growing certain plants alongside cannabis to repel pests or attract beneficial insects. Marigolds, basil, and dill are known to deter pests, while flowers like sunflowers and yarrow attract pollinators and beneficial insects. Consider incorporating these companion plants into your outdoor grow space to naturally protect your cannabis plants.

Integrated Pest Management

Integrated Pest Management (IPM) is a holistic approach to pest control that combines prevention, monitoring, and intervention strategies. Regularly inspect your plants for signs of pests or diseases, such as yellowing leaves, chewed foliage, or webbing. If you identify an issue, consider using organic pest control methods, such as neem oil, insecticidal soaps, or beneficial insects, to address the problem.

Proper Sanitation

Maintaining proper sanitation practices in your outdoor grow space is essential for preventing the spread of pests and diseases. Remove any dead leaves or plant debris from the area, as they can provide a breeding ground for pests and pathogens. Regularly clean your tools and equipment to minimize the risk of contamination.

Organic Pest Control

If organic pest control methods are not effective in controlling pests, you may need to consider using chemical pesticides as a last resort. However, exercise caution when using chemical pesticides, as they can have adverse effects on the environment and beneficial insects. Always follow the instructions on the pesticide label and apply them sparingly and judiciously.

By implementing these pest and disease management strategies, you can protect your cannabis plants and ensure their health and vitality throughout the growing season.


Supporting Your Cannabis Plants with Staking

As your cannabis plants grow taller and develop heavier buds, they may require support to prevent them from bending or breaking. Staking your plants provides the necessary stability and helps ensure proper airflow and light penetration. Here’s how to stake your cannabis plants effectively:

Choosing Stakes

Select stakes that are sturdy, durable, and long enough to support the height of your plants. Bamboo or wooden stakes are popular choices, as they are readily available and provide adequate support. Avoid using stakes that are too thick, as they may damage the roots when inserted into the soil.

Positioning the Stakes

Place the stakes in the ground around each plant, ensuring that they are positioned a few inches away from the main stem. Drive the stakes into the soil until they are firmly anchored and provide sufficient support for the plants.

Tying the Plants

Gently tie the main stem of each plant to the stake using soft plant ties or garden twine. Make sure the ties are secure but not too tight, as they need to allow for natural movement and growth. As the plants continue to grow, adjust the ties to accommodate their increasing height and weight.

By staking your cannabis plants, you provide the necessary support for their vigorous growth and protect them from potential damage.

Harvesting and Curing Your Bountiful Buds

After months of careful cultivation, the time will come to harvest and cure your bountiful buds. Follow these steps to ensure a successful harvest:

Determining Harvest Time

Clear | Cloudy | Amber Trichomes

The right time to harvest your cannabis plants depends on the specific strain and your desired effects. As the plants approach maturity, the trichomes (resin glands) on the buds will change color from clear(Green Arrows) to milky(Yellow Arrow) or amber(Red Arrow). Use a jeweler’s loupe or a magnifying glass to inspect the trichomes and determine the optimal harvest window.


To harvest your cannabis plants, use clean pruning shears or scissors to cut the branches just above the main stem. Handle the plants gently to avoid damaging the buds. Remove any large fan leaves, leaving only the smaller sugar leaves surrounding the buds.


Drying and Curing

After harvesting, hang the branches upside down in a dark, well-ventilated area with temperatures around 60-70°F (15-21°C) and humidity levels between 45-55%. Allow the buds to dry slowly for about 1-2 weeks until they feel dry to the touch and the smaller stems snap instead of bend.

Once dried, trim the buds and place them in glass jars, filling them about 3/4 full. Store the jars in a cool, dark place and open them daily for a few minutes to release any excess moisture. This curing process allows the buds to develop their full flavor, aroma, and potency.

By following these steps, you can enjoy the fruits of your labor and savor the delightful flavors and effects of your homegrown cannabis.


Growing cannabis outdoors provides a rewarding and cost-effective way to cultivate your own supply of high-quality buds. By understanding the legalities, choosing the perfect location, preparing the soil, selecting the right strains, starting your seeds or clones, transplanting your plants, providing adequate water and nutrients, protecting your plants from pests and diseases, supporting them with staking, and harvesting and curing your bountiful buds, you can create the best outdoor grow setup for cannabis. Enjoy the journey and the abundant rewards of your outdoor cannabis grow!
