Plantra Grow Tubes

These grow tubes are designed for a wide range sunlight conditions which receive a minimum of 6 hours of uninterrupted sunlight per day during the growing season.

Unlike traditional tree tubes and tree shelters Greenhouse Grow Tubes are twin-walled for light diffusion and translucent to growth-optimizing sunlight trees and shrubs need. Grow tubes are packed with advanced greenhouse technology to stimulate phytochrome to grow the whole plant from roots to shoots necessary to get your new seedlings off and running with the sun. In addition to superior greenhouse benefits they are engineered with cross-flow venting to promote effective air movement and increase CO2 replenishment, reduce excessive moister buildup and encourage proper dormancy before winter.
