Pro/Gro tubes stimulate rapid height growth. These tubes effectively increase carbon dioxide levels, relative humidity and temperature within the tube. The effect is a miniature greenhouse and accelerated photosynthesis. Pro/Gro tubes protect against wind desiccation, deer and elk browse, rabbits and small rodents. By linking two or more of the sheets together you can tailor the tube diameter to meet your needs.
Comes with a 3' bamboo stake for installation.
