An integrated hydroponic system including subsystems for support and movement of plants, controlling the atmosphere around the plants and nutrient distribution. The support and movement subsystem features diverging trough-in-trough construction where the interior trough is formed by discrete autoclavable plastic troughs which are slidably removable for sanitation purposes from supporting exterior troughs which in turn support nutrient distribution tubing and a rotatable variable pitch drive screw for moving individual plant holders along the troughs in graduated increments. The atmospheric control system features supply and exhaust ducts under the troughs which establish a blanket of air in the zone proximate to the trough where the temperature, humidity and carbon dioxide concentration are regulated. The nutrient distribution system involves recycling the thermally and component regulated dilute nutrient fluids from a reservoir to the plants and back into the reservoir.
