Hydroponic equipment allows to resolve a problem of supply with fresh greenery, vegetables and fruits for quite different countries and regions regardless climatic conditions, type of soil and availability of natural water resources. In developed countries there is a continuous and significant requirement of an all-the-year-round production of wide range crops for the population and enterprises of food and processing industry. By our notion, a rational mean of increase of efficiency of functioning of large hydroponic complexes, their further development and improvement is automation of all technological and auxiliary operations of the corresponding production process beginning from receipt orders and up to delivery of ready products to consumers. Solution of this task will provide effective using of time and material resources (areas, soil, equipment, energy, nutrients, microelements, water), more even loading and operation of productive capacities, increase of productivity of enterprises and quality of ready products, decrease of their prime cost. There is conducted an analysis of main types of control devises and their executive elements (mechanical, hydro-mechanical, pneumatic-mechanical, electro-mechanical), their advantages and shortcomings. Also, the work contains an elaborated a structural scheme of an automated regional hydroponic production-logistic association, that provide production and delivery to consumers greenery, fruits and vegetables. There is proposed a block-scheme of an algorithm, ensuring rational automatic functioning of hydroponic technological complexes with examination of volumes and content of consumer orders, qualitative characteristics of the products, admissible terms of the orders fulfilment, availability of hydroponic equipment, its capacity and technological possibilities.
