Growing sativas outdoors is an attractive option for many cannabis growers, as these plants are known for their impressive height and width. Sativas can grow up to 3-4 meters tall and very bushy under ideal conditions. In this article, we explain how you can grow feminized sativas very tall and high yielding. We'll discuss the advantages of sativas compared to indicas and also look at the role of hybrids.
Growth and Size of Sativas
Sativas are known for their slender and tall growth habit, in contrast to the shorter and bushier Indicas . An important prerequisite for successful cultivation is the right choice of location that offers sufficient space and light.
Important Factors for Large and Yielding Plants
-
Important Factors for Large and Yielding Plants
-
seeds
- Choose robust feminized sativa outdoor strains : The right choice of strain lays the foundation for healthy, large cannabis plants.
-
root growth
- Focus on strong root development in the first few weeks : A strong root system is crucial for the growth of large plants.
- Tip : Use special root growth fertilizers in the first few weeks.
-
soil/substrate
- Use well-drained, nutrient-rich medium : High-quality soil supports nutrient uptake and growth.
-
Regular watering
- Keep the soil evenly moist but avoid waterlogging : Adequate watering is important to keep the plants healthy and strong.
- Warning : DO NOT DROWN
-
sunlight
- The more light the plant receives, the larger and more productive it will be : Outdoor sativas need plenty of direct sunlight for optimal growth.

Place
- A cannabis plant that is to grow large and tall needs a lot of space : both for the roots and for the plant itself to grow in width and height.
- Tip : Make sure there is enough space between the plants.
-
nutrient supply
- Ensure a balanced supply of nutrients, especially during the growth phase : proper fertilization promotes growth and flowering.
- Recommended fertilizers : NPK 3-1-2 in the growth phase, NPK 1-3-2 in the flowering phase.
- Fertilizer rhythm : Every two weeks during the growth phase, weekly during the flowering phase.
-
pest and disease control
- Check regularly for pests and diseases and act immediately if problems arise : Regular inspection will protect your plants from damage and loss.
- Tip : Better safe than sorry.
-
air circulation
- Promote good air circulation to prevent mold and disease : Good ventilation keeps plants healthy and reduces the risk of fungal infections.
-
patience and care
- Growing large outdoor plants requires patience and consistent care : Be aware that not every plant will grow huge and plants have different phenotypes (or "DNA").
- Tip : Make the most of the genetics you are given. Continuous attention and care are crucial for success.
-
μmol m-2 s-1 is a unit of measurement for light intensity or luminous intensity, which is crucial for plant growth. It stands for micromoles per square meter per second and measures the amount of light that hits a surface per square meter of area per second.
By considering these factors, you can ensure that your sativa plants grow large and productive, resulting in a successful harvest.
Advantages of Sativas over Indicas
- Taller plants : Ideal for outdoor cultivation as they can take advantage of a lot of space and light.
- Longer flowering time : Often results in higher yields.
- Energetic high : Sativas are known for their cerebral and invigorating effects, making them preferable for daytime use.
hybrids
Hybrids combine the best characteristics of sativas and indicas. They can combine the height and yield of sativas with the robustness and shorter flowering time of indicas. This makes them versatile and suitable for different growing conditions.
fertilization and irrigation
- Fertilizer recommendation : Use a balanced fertilizer with a ratio of NPK (nitrogen, phosphorus, potassium) of 3-1-2 in the growth phase and 1-3-2 in the flowering phase.
- Watering Tips : Keep the soil evenly moist but avoid waterlogging. Water deeply and allow the soil to dry out slightly between waterings.
- Fertilization rhythm : Fertilize every two weeks during the growth phase and weekly during the flowering phase.
training techniques
Training is crucial to unlocking the full potential of your Sativa cannabis plants. Here are some methods:
- Low Stress Training (LST) : Bend and tie the branches to bring more light to the lower parts of the plant.
- Screen of Green (SCROG) : Use a net to distribute the branches horizontally to ensure even light distribution.
- Topping : Cut off the top of the plant to encourage the growth of side shoots and create a bushier plant.
Timeline for Outdoor Sativa Cultivation
March - April:
- Germinate seeds : Start seeds indoors or in a greenhouse.
- Focus on root formation : Use special root growth fertilizers.
May:
- Putting plants outside : As soon as there is no longer any danger of frost, put the young plants outside.
- Start training : Start with LST or topping to encourage growth.
June - July:
- Vegetative growth : Plants should grow quickly in height and width.
- Fertilize regularly : Use NPK 3-1-2 fertilizer every two weeks.
August - September:
- Initiate flowering phase : Switch to NPK 1-3-2 fertilizer and increase the frequency.
- Observe flower development : Watch for pests and diseases.
October:
- Harvest time : Depending on the variety, the harvest can begin in early or mid-October.
- Drying and Curing : Harvest the plants and dry the flowers properly.
Well-known Sativa grower
An example of a well-known sativa grower who grows extremely wide and tall sativas is Jorge Cervantes. He is a respected figure in the cannabis community and is known for his expertise in growing various cannabis strains, including sativas. His books and videos on cannabis cultivation are popular and have helped many growers successfully grow their own plants. Cervantes is known for producing high-quality sativas that are not only tall but also of excellent quality. His experience and expertise have made him a trusted source for cannabis growing tips and techniques.
With proper care, sufficient light and targeted training techniques, you can grow impressive 3-4 meter tall sativa plants with high yields. Hybrids offer a flexible alternative by combining the best characteristics of both cannabis species. Follow the tips for fertilization and watering mentioned above to ensure your plants are optimally cared for and grow into large, healthy specimens.
