Hydroponic Glossary terms Defined


In the world of hydro growing, there are quite a few terms that newcomers often don't understand. Here is some of the most popular terminology in the hydroponics world that beginners may need to reference.


In hydroponics, chelation refers to the method by which plants digest nutrients. This is something growers will ask about if they need to figure out how to make sure plants are actually using elements like calcium, nitrogen, phosphorus or any other chemicals that are put into plant nutrient packages.


Cloning refers to taking live cuttings of plants, and helping those to develop their own root systems to become mature plants. Clones often need different growing environments, because they are more sensitive than plants that already have developed root systems.


Flushing involves changing out the water that plants get nutrients from, to either make it more sanitary and clean, or to introduce new elements for quick feeding and growth.

Foliar feeding

Foliar feeding, sometimes called FogPonics, involves spraying or misting plants with a nutrient-rich solution. It's a supplementary way to feed plants if they're not getting what they need through their roots.


This is an abbreviated nickname for nutrients.

nute burn

In a case of nute burn or nutrient burn, plants are getting too much of some chemical, and it's causing them to wither or fail to thrive.


The reservoir is the body of water that is kept on hand to irrigate hydroponic plants.


Sea of green (SOG) or screen of green (SCROG) refer to specific growing methods that help to develop a canopy for plants inside a grow box or grow system. These methods have been shown to help develop plants a lot better in some cases.

these are just some of the basic terms that beginners many help with when they start their first hydroponics project. For more, check out all the equipment and products available to help you build a successful hydroponic garden.
