These ingeniously designed plant sleeves create a microclimate for each tender vine that protects it from damaging UV rays. Your vines will not only survive, they’ll thrive because the root-to-shoot ratio will be even.
The patented grow tubes permit the ideal mix of red and blue light to penetrate. This increases the photosynthesis rate during early establishment, resulting in a stronger root system, wider caliper growth of the stem or trunk and faster growth overall. A bonus: Blue-X Grow Tubes also guard against curious animals and chemical spray/drift. Can also be used on very young trees.
The durable tubes are made with pure resins and UV inhibitors, and will protect young vines for as long as 5 years. Each tube is 9 cm (3.5”) across. Easy two-part assembly.
