A porous glass plant growth support structure, including a porous glass substrate and a plurality of interconnected pores distributed throughout the substrate. The substrate is typically formed from foamed glass and/or fused glass spheres and is characterized by a porosity of at least about 80 percent. The pore size is substantially between about 0.2 and about 5 millimeters and the substrate is sufficiently chemically stable such that water filling the plurality of interconnected pores experiences a pH shift of less than 0.5.

L'invention porte sur une structure de support de croissance de plante en verre poreux, comprenant un substrat de verre poreux et une pluralité de pores interconnectés distribués dans tout le substrat. Le substrat est typiquement formé à partir de verre expansé et/ou de sphères de verre fondu et est caractérisé par une porosité d'au moins environ 80 pour cent. La taille des pores est sensiblement entre environ 0,2 et environ 5 millimètres et le substrat est suffisamment chimiquement stable pour que l'eau remplissant la pluralité de pores interconnectés subisse un décalage de pH de moins de 0,5.
