BLUE-X®: The growtubes that minimize field costs while maximizing vine growth.
Use BLUE-X® Grapevine Shelters to create a beneficial microclimate for each grapevine. The increased humidity and carbon dioxide levels in the growtubes accelerate plant growth and enhance vine survival.
BLUE-X® Grapevine Shelters are available in 15 inch (38 cm.), 24 inch (60 cm.), 30 inch (76 cm.), and 48 inch (122 cm.) heights. All Grapevine Shelters are 3.5 inches (9 cm.) in diameter. We can also supply custom heights.
BLUE-X® Grapevine Shelters, a partially post consumer recycled product, are fabricated from a transparent blue tinted polyester film (PET), (PART-A). This blue film admits up to 100% more photosynthetically active radiation (PAR) than opaque polpropylene. PAR is the part of the light spectrum most used by plants.

Use BLUE-X® to increase the diameter of your vines! We offer the only shelter on the market today that takes advantage of beneficial blue light!
BLUE-X® Grapevine Shelters are constructed using a patented two piece method. The growtubes are packaged flat and the two pieces can be assembled very quickly.
To assemble a single sheet of blue plastic film (Part A) is rolled up and inserted into a blue-tinted poly sleeve (PART-B) open at both ends. When the Grapevine Shelter is no longer needed on the vine, it can be removed by slitting the poly sleeve (PART-B). Once removed, the poly sleeve (Part-B) can be recycled. The polyester film (Part-A) can than be stored for reuse the next season. Replacement poly sleeves can be purchased separately if needed.
