Rockwool is very common, especially among horticultural professionals; the majority of tomato crops from the food industry are grown on this substrate. Rockwool is known for its ability to retain water and nutrients, so its irrigation requires great attention from the grower insofar as it must be programmed and spaced evenly over the lighting time of the plants, in order to meet their needs.
