Container for cultivating plants without soil has substrate in bag with heat exchange fluid duct for heating substrate

摘要

The container for cultivating plants without soil has a substrate (1) in a bag (2). The bag is formed of a material with a high thermal coefficient of conduction with two sidewalls and a base (2a) forming a spout. Each sidewall has a duct (5) for a heat exchange fluid which is used to heat the substrate.
