To view a copy of this license, visit http: Abstract Hydroponic systems have been utilized as one of the standard methods for plant biology research and are also used in commercial production for several crops, including lettuce and tomato.

Within the plant research community, numerous hydroponic systems have been designed to study plant responses to biotic and abiotic stresses. Here we present a hydroponic protocol that can be easily implemented in laboratories interested in pursuing studies on plant mineral nutrition.

This protocol describes the hydroponic system set up in detail and the preparation of plant material for successful experiments. Most of the materials described in this protocol can be found outside scientific supply companies, making the set up for hydroponic experiments less expensive and convenient.

The use of a hydroponic growth system is most advantageous in situations where the nutrient media need to be well controlled and when intact roots need to be harvested for downstream applications. We also demonstrate how nutrient concentrations can be modified to induce plant responses to both essential nutrients and toxic non-essential elements.

Hydroponics is a method of growing plants that takes advantage of this fact by providing all of the nutrients, in their inorganic form, in a liquid solution with or without solid media.

Hydroponic systems have been extensively used by scientists for exploring nutrient requirements and also the toxicity of some elements in Arabidopsis and other plant species For instance, Berezin et al.

Industrial applications of hydroponics have also been developed for crops such as tomato and lettuce6. Here, we outline the use of hydroponics in the context of research, possible variations in available methods, and finally present a system that can be easily scalable and useful for research laboratories interested in studying plant mineral nutrition.

Hydroponic systems allow for easy separation of root tissue and precise control of nutrient availability Hydroponics offers several advantages over soil-based systems. When removed from soil, root tissue is often mechanically sheared causing loss of tissue or damage.

This is particularly true for fine root structures such as lateral roots and root hairs. In soil systems, nutrient bioavailability changes throughout the soil matrix as nutrients bind to soil particles creating micro-environments within the soil.

This heterogeneity could add an extra level of complexity in experiments needing a precise control on the external concentration of nutrients or other molecules.

Hydroponics - an introduction

In contrast, the hydroponic solution is homogeneous and can be easily replaced throughout the course of the experiment. Variants of hydroponic systems All hydroponic cultures rely on a nutrient solution to deliver essential elements to the plant. In addition to the nutrients, the roots also need a steady supply of oxygen.

When roots become anoxic they are unable to take up and transport metabolites to the rest of the plant body7. Hydroponic systems can be classified based on how they deliver oxygen and other nutrients to the roots: In hydroponics, nutrient solution can be saturated with air prior to its use and changed frequently, or air can be continuously supplied in the solution over the life cycle of the plant9.

Alternatively, plants may also be grown on inert media e. In aeroponics, roots are sprayed with the nutrient solution to prevent desiccation.

Disadvantages of hydroponic systems Although hydroponic cultures offer clear advantages over soil-based systems, there are some considerations that must be acknowledged when interpreting the data.Hydroponics is basically growing plants without soil.

It is a more efficient way to provide food and water to your plants. Plants don’t use soil – they use the food and water that are in the soil. Hydroponics by definition, means 'water-working." In practical use, it means growing plants in a water and nutrient solution, without soil.

Hydroponics allows a gardener to grow plants in a more efficient and productive manner with less labor and time required. Hydroponics - an introduction. Hydroponics is the science of growing plants without soil, either through placing the plants in a container of solution (known as solution culture), or through using another medium such as gravel or sand (known .

The systems are completely pre-wired, UL listed (with lens), and ready to plug in. Everything is rated at volts (your normal home current) and plugs into any standard home outlet.
