When the Liberal government of Canada legalised recreational use of cannabis late last year, it created a whole new industry virtually overnight.
One aspect has been a massive rise in greenhouse building and conversion of former manufacturing plants into commercial grow-ops.
But questions were quietly being raised about whether the potential lucrative crop would replace food growing farm operations.
Up until recently, almost all commercial cannabis has been grown indoors, primarily for security reasons.
But of course, a substantial percentage of Canadian vegetables have long been grown in greenhouses as well. Now, several former massive greenhouses which only a year ago provided bell peppers, tomatoes and other food crops have since been converted to producing the drug crop.
