These tiny 90-degree benders will help you reorient the stems in the desired direction for better yields. The following manual training technique is called low-stress training (LST), and it involves manipulating the shape of the plants to produce better yields, while controlling the height and shape of the plants. Do low-stress training to create multiple blooming points and allow light to be distributed more evenly and reach more leaves. Increase light penetration: Control the height and shape of the plant to even out the canopy so that light can reach all parts of the plant. Increase Yield: Creates multiple flow sites in addition to the main stem. Increase airflow: Reorient the stems to allow better airflow to help disperse moisture and reduce the chance of mold growth. Easy Installation: Gently bend the stem back and forth, then insert the tube bender onto the stem. EASY REMOVAL: Made in vibrant colors for easy detection in dense foliage. Easy to find and delete. Reusable: Made of PETG, a strong, durable and impact-resistant plastic. Can be reused for multiple growths. Dimensions: 3 x 1 cm / 1.18 x 0.4 inches Package Contents: 30 x Plant Benders
