 Acidic

 The PH of a solution can be tested on a scale from 0 - 14 to determine if it is acidic or alkaline. A PH reading of 7.0 is neutral and anything below this is considered to be acidic, e.g. 6.5 slightly acidic, 2.5 very acidic

Active

An active hydroponics growing system requires a pump or components to actively move stored water and nutrients around the system to feed your plants.

Additive

Additives or boosts can be supplied in the water with your regular nutrients and are designed to maximise your plants potential when growing, fruiting or flowering. Additives that are designed to boost plants in the flowering period mainly contain high levels of phosphorus (P) and potassium (K).

 

Aeration

To provide air or oxygen to soil and plant roots. Enzymes can be a very handy product for helping to aerate your soil, as they break down dead root material from your plants, fast.

  

Aeroponics

True aeroponics is created with the minimal amount of contact between a plant and support. A single line of contact around the stem of the plant for support, allows 100% of the plant to be totally suspended in the air. Plants can grow above the support structure and the roots are suspended below the support structure, in the air, inside a dark chamber, and misted or sprayed permanently or regularly (timed intervals). A fine mist does not create true aeroponics, but water droplet size is important. Too large of a water droplet means less oxygen is available to the roots, and too fine of a water droplet produces excessive root hairs and develops a poor lateral root system, needed for sustained growth in aeroponic systems.

Alkaline

The PH of a solution can be tested on a scale from 0 - 14 to determine if it is alkaline or acidic. A PH reading of 7.0 is neutral and anything above this is considered to be alkaline, e.g. 7.5 slightly alkaline, 12.5 very alkaline.

Alternating Current (AC)

An alternating current is an electrical current that alters the direction it travels several times a second.

Amino Acid

Amino acids are molecules that are critical to life and are the building blocks of proteins and enzymes. Amino acids are essential to the structure and metabolism of plants.

Ampere (AMP)

An ampere (amp) is a unit to measure and gauge the strength of an electrical current.

Annual

A plant that completes its entire life cycle in one year or less is known as an annual.

Aphids

Aphids, commonly known as greenfly, blackfly or plant lice are soft bodied insects that come in a variety of colours. They are among the most destructive pests that we encounter in our hydroponics grow rooms or outdoor gardens. Aphids suck the sugary sap from your plants and then excrete it back over the plant, producing a sticky layer on which moulds can grow. These insects live in large populations and can destroy crops with ease.
