EBB & FLOW

Ebb and Flow, also known as flood and drain is a method for hydroponics cultivation. This method stores water and nutrients in a main tank, and a pump delivers the nutrient solution into the tray or pots of the growing system to flood the media and plant roots to water and feed them. The solution is then drained from the tray or pots of the growing system, as the solution drains it pulls large amounts of air and oxygen into the media and root zone of the plants. 

ELECTRICAL CONDUCTIVITY (EC)

A method for checking the strength of a nutrient solution is to measure how well it conducts electricity. As salts (nutrients) are added to the water it increases the flow of electricity. Measuring the EC (electrical conductivity) with a meter gives a direct indication of the nutrient strength in a solution.

EMBOLISM

An embolism is a blockage in the plants vessels, usually created by an air bubble.

ENZYMES

Enzymes are biological proteins that accelerate the rates of chemical reactions but do not change themselves. Enzymes are added to nutrients and additives to speed nutrient uptake through roots and also assist and speed up the process of breaking down dead root material, and enzymes also activates micro-organisms to develop new root growth fast.
