Greenhouses (as well as solar greenhouses) offer opportunities for off-season cultivation of vegetables as well as opportunities for weed growth. Weeds and vegetables fight fertilizer, light, carbon dioxide, affecting the yield and benefits of vegetables, the application of herbicides can effectively eliminate weeds.
