Plant support \"Rank-O-Flex\" - Flexible growth support for climbing plants Thanks to the plant support \"Rank-O-Flex\" by Bio Green, each type of climbing plant gets the flexible support it needs: the rings can be adjusted individually to the growth of each individual plant. Simply move the plant support gradually upwards and the climbing plant grows automatically with it. This way the lush growth of vegetables and ornamental plants is guaranteed. Our plant support is particularly suitable for tomato plants that tend to fall over. \"Rank-O-Flex\" can be fixed on bamboo poles, construction steel, sticks and rods with a diameter of up to 4 cm (approx. 1.6 in) with one screw, and adjusted as desired.
