TUBEX VENTEX tree shelters are ideal for warmer climates as the shelter includes ventilation holes and a modified colour for light transmission. Early trials on treeshelters in warmer climates produced the expected improvements in establishment and growth, but this was tempered by concerns about insufficient stem diameter. As a result, Tubex undertook research in the early 1990’s through INRA in France and jointly developed the Tubex ‘Equilibre’ treeshelter (now known in the UK as Ventex).
TUBEX VENTEX treeshelter improves growing conditions for trees in warmer climates by modifying the traditional treeshelter balance of air (primarily CO2), air humidity and light to produce ‘optimum’ growing conditions where these elements are in ‘equilibrium’. These modified conditions are produced specifically sized and positioned ventilation holes and a modified shelter colour and light transmission profile.
