There is no definitive answer to this question, as the best training methods for your indoor grow depend on the goals and preferences of the grower. However, some general factors that can help to choose the best method are: The space: The available space in the grow room or tent can determine the optimal height and width of the plant. Smaller spaces may require more pruning and training to keep the plant compact and manageable, while larger spaces may allow more freedom and flexibility for the plant to grow. The grow lights: The type and intensity of the light source can influence the growth and development of the plant. High-intensity lights, such as HID or LED, can produce more heat and stress for the plant, which may require more pruning and cooling. Low-intensity lights, such as CFL or T5, can produce less heat and stress for the plant, but they may also require more training and manipulation to ensure adequate light exposure. The style: The desired shape and structure of the plant can reflect the personal style and creativity of the grower. Some growers may prefer a simple and symmetrical shape, such as a scrog or sog, while others may prefer a more complex and diverse shape, such as a manifold or flux. Ultimately, the best training methods for your indoor are the ones that suit your needs, preferences, and abilities as a grower. Experimenting with different methods can help you discover what works best for you and your plants.
