Answer 2

Hello Dear, This is really difficult to answer the number of hydroponic farms as this is going on from last 18 years. and farms are increasing day by day. So to number out the farms is not possible and this require a survey or need to know where are they get registered. So you can count the number of registered farms but calculating it all over the world is really not possible I searched for this answer nearly half an hour but don't got any satisfactory answer... So Sorry
