Blue-X provides protection from animals, chemical sprays, and weed trimmers.
Field studies of vine shelters have shown increased growth rates of 100-150% when using Blue-X grow tubes.
This patented two-part Blue-X grow tube has an outer plastic sleeve which encircles a transparent blue-tinted polyester film.
This film admits up to 50% more photosynthetically active radiation (PAR) which is the part of the light spectrum that is most used by plants.
At the end of the season (Blue-X grow tubes should be removed a few weeks before the first frost), the outer plastic sleeve can be easily cut away and discarded while the inner plastic can be stored flat and new outer sleeves purchased for reuse.
Individual and box quantities sold with both parts A and B.
