In the project ‘Vertical Farming 2.0 - Just Add Water’, a pilot line is being developed to produce the Holland Bioproducts grow plug in series. The biodegradable jute grow plug has been developed as a sustainable alternative to rock wool, peat and coconut. Grow seed and biostimulant have been applied to the plug, making it a ready-to-use product (‘add water only’). This is ideal for vertical cultivation and greenhouse growers who want to save on operational costs. Due to the perfect air and water balance, the plug is ideal for the cultivation of vegetables, herbs, berries and ornamental plants.
