In the early 1990’s vineyard managers discovered the benefits of grow tubes:
- Uniform Growth or Rapid vine growth and vineyard establishment – you typically harvest your first crop 1 year sooner, and ramp up to full harvest levels faster
- "Automatic" vine training- you save several passes through the field to train viens, since grow tubes guide them to the cordon wire
- Faster, easier and more effective weed control- grow tubes shield vines from herbicide spray and mechanical cultivators, greatly facilitating first year weed control
Plantra’s Vine Grow Tube have everything you should look for in a grow tube:
- 3.5 inch diameter for thicker stems and balanced root to shoot ratio
- Peach color to optimize photosynthesis (while allowing blue light in the top of the tube where is belongs)
- Twin wall (corrugate) construction, both for rigidity and to diffuse light for optimal photoreception
- Side-opening slit, so the tubes can be removed after vines are trained to the wire and compactly stored for re-use
