Answer 36

Hydroponics

Question 37

The most common method of soil- less culture is hydroponics, which includes growing plants either on a ____ or in an ____ with bare roots.

Question 39

____ supplies the plants’ roots with a thin film of nutrients. Characterized by a continuous flow of a thin film of nutrient-rich water over the plant roots.

Answer 39

Nutrient Film Technique (NFT)

Question 40

This systems are popular for their efficiency and ability to deliver nutrients directly to the root zone.

Answer 40

Nutrient Film Technique (NFT)

Question 41

Type of hydroponic system where plant roots are suspended in the nutrient solution and the air is provided directly to the roots with an air stone or diffuser. The platform that holds the plants is usually made of Styrofoam and floats directly on the nutrient solution.

Answer 41

Deep Water Culture (DWC)

Question 42

The _____ is by far the simplest type of hydroponic system. This is a passive system, which means there are no moving parts. The nutrient solution is drawn into the growing medium from the reservoir with a wick. Plants roots are suspended in the nutrient solution and the air is provided directly to the roots with an air stone or diffuser.

Answer 42

Wick system

Question 43

The ______ works by temporarily flooding the grow tray with nutrient solution and then draining the solution back into the reservoir. This action is normally done with a submerged pump that is connected to a timer.

Answer 43

EBB and Flow & Drain System

Question 44

With this system, the nutrient solution is pumped through tubes directly to the base of the plant. At the end of the tubes are drip emitters that allow the nutrient solution to drip at an adjustable flow, saturating the grow medium. It has 2 systems: Circulating systems and Non-recirculating systems

Answer 44

Drip Systems

Question 45

The most high-tech type of hydroponic gardening. Like the N.F.T. system above the growing medium is primarily air. The roots hang in the air and are misted with nutrient solution. The mistings are usually done every few minutes. Because the roots are exposed to the air like the N.F.T. system, the roots will dry out rapidly if the misting cycles are interrupted. A timer controls the nutrient pump much like other types of hydroponic systems, except this system needs a short cycle timer that runs the pump for a few seconds every couple of minutes.

Answer 45

Aerophonics

Question 46

_____ is the integration of recirculating aquaculture and hydroponics in one production system. In this unit, water from the fish tank cycles through filters, plant grow beds and then back to the fish.
