A Blue Box for substrates

摘要

Fvery year, the North American greenhouse industry uses more than 250,000 cubic metres of growing substrates. But finding a sustainable answer for used substrate is a growing concern for the industry. Grodan has an answer. Albert Mastronardi looks over the 24 acres of greenhouse vegetables, including cluster and beef tomatoes and mini-cucumbers, in Kingsville, Ontario. He sees a lot of opportunity that, in the past, has simply gone to waste.
