These tiny 90 degree benders will help you reorient your rods in the direction you want for better yields. The following manual training technique is called low stress training, it involves manipulating the shape of plants to produce higher yields whilecontrol the height and shape of your plants. Low stress training is done to create multiple bloom sites and to allow light to be more evenly distributed and reach more leaves. Increase light penetration: Control plant height and shape to even out the canopy so light can reach all partsof the plant. Increase Yields: Creates multiple fluid sites in addition to the main stem. Increase Airflow: Reorient stems to allow for better airflow to disperse moisture and reduce the chance of mold growth. Easy installation: gently bend the rods back and forth, then insert the bender onto the rod. Effortless Removal: Crafted with vibrant colors for easy detection in dense foliage. Easy to find and remove. Reuse: Made from a strong, durable and impact resistant plastic. Reusable for multiple crops. Size: 3 x 1 cm / 1.18 x 0.4 inches Package Contents: 30 x Plant Bender White
