What is hydroponic plant growing and its benefits?

Hydroponic plant growing is the cultivation of plants without using soil.  It’s a water-based plant system providing nutrients, hydration and oxygen to feed the root system.

Water is oxygenated with a pump or through a drip method, which is vital in keeping plants alive and thriving.  This fosters rapid growth, sturdier yields and better plant quality. If the root system is exposed directly to water and nutrition, the plant does not need to exert energy in sustaining itself.


The advantages of hydroponic growing


With hydroponics, direct exposure to nutrient-filled water can be a more effective and versatile way of growing versus traditional irrigation. There are several advantages to growing hydroponically compared to conventional growing practices.

  • Fast growing. Hydroponics reduces the time needed to produce plants. They can be grown without the need to cultivate, weed and mulch. Watering and fertilising can also be automated.


  • Reduction in pests and diseases. Only a small number of seedlings are required to produce what you need. Plant loss from pests and disease are greatly reduced when grown hydroponically, especially if the plants are in a protective structure.

  • Water efficiency. Hydroponics use less water than traditional agriculture.

  • High yielding and space saving. Hydroponic growing is highly efficient. It requires low capital cost while producing higher yields with less labour input – ideal for commercial growers. This form of growing also takes up less space.

Introducing some top Bluelab products for your hydroponic growing


Bluelab pH Pen

Plants get their nutrients from minerals but they can only get all the right minerals needed if certain conditions are right. A key factor that affects food uptake is whether your solution is acid or alkaline, which is measured in pH.

The Bluelab pH Pen also measures the temperature of the solution, as root health is vital to the success of a crop. Temperature affects the growth rate and structure of a plant so a solution temperature of 18 - 22˚C or 65 - 72˚F is recommended.

The handheld pH Pen provides a compact quick and handy way to ensure maximum uptake of nutrients for your crops. It has selectable units for temperature, a backlit display and is fully waterproof – ideal for hydroponic growing.

Bluelab Guardian Monitor

The Bluelab Guardian Monitor provides 24-hour continuous reading for pH, conductivity and temperature within a nutrient solution.

Designed for indoor use, the Guardian Monitor can be mounted on a wall or hung on a support bar. Set up your reservoir, place the pH and conductivity probes in the solution, then adjust and glance. If the solution moves away from the ideal range, the display flashes. A quick look at the monitor will let you know when your nutrient solution needs adjusting.
