Glossary Of Grower & Gardening Terms


Term What Is It? Why Do I Care?
Acidic On a pH scale, your growth medium is acidic or "sour" if it has a pH level of less than 7 If your growth medium is too acidic, it will decrease the availability of plant nutrients
Alkaline Alkalinity measures the acid in a substance. pH measures that amount. A substance is alkaline (or basic) if it has a pH of over 7 If pH is too high, nutrients will not dissolve as well and will not be absorbed properly, so you'll see deficiencies
Aquaponics System of aquaculture that uses aquatic animals to provide nutrients for plant growth. Plants then purify the water This may be a great option for you if you're looking to reduce water consumption and grow in a natural ecosystem without pesticides and fertilizers
 Cloning  The process of creating a new plant that's genetically identical to the first unit  Cloning will save time and space in your garden, but there's a risk of bad genetics if you're getting external clones. Additionally, they may have a less robust root system than a plant grown from seed.
 CO2  Carbon dioxide  Higher concentrations of carbon dioxide make plants more productive - they can produce more food and grow more quickly
 Coco coir  Coco coir is a coconut fiber husk alternative to traditional soil  Coco coir can hold a high water capacity but allows for more air flow than other options. You can feed your plants more often and grow them larger in coco
 Drip Irrigation  A system of crop irrigation involving controlled delivery of water directly to plant roots  Drip is the most efficient water and nutrient delivery system for growing plants
 Electrical Conductivity (EC)  Conductivity measures the amount of salts in your growing medium  Excess salts occur naturally in more arid climates and can hinder or halt plant growth
 Fermentation  A chemical process in horticulture that releases enzymes and probiotics  All fresh fruits, vegetables and herbs are natural hosts to bacteria. Fermentation encourages beneficial bacteria to participate in the preservation process of those fresh plants.
 Foliar Spray  System to apply fertilizer directly to plant leaves rather than adding to the soil  Foliar spray isn't a replacement for good soil, but it will get to work much quicker than through the soil via plant root and stems. It is often used if you are having issues with nutrient lock out or as a secondary means for feeding
 Hydroponics  The process of growing plants in sand, gravel, coco coir or liquid - with added nutrients, but without soil  Hydroponics means more than water - there are many ways to grow outside of traditional soil
 MacroNutrient  Plant nutrients required in the largest amounts - carbon, hydrogen, nitrogen, oxygen, phosphorous & potassium  Anything that you're growing will need these nutrients!
 MicroNutrient  Plant nutrients required in tiny amounts - boron, chlorine, copper, iron, manganese, molybdenum, zinc  Anything that you're growing will need these nutrients!
 N-P-K Label  Measurements in a nutrient that indicate the amount of Nitrogen (N) Phosphorus (P) Potassium (K)  These are the three macro nutrients used by ALL plants for photosynthesis
 Nutrient  Chemical elements and compounds necessary for plant growth.  Without them, the plant cannot complete it's life cycle. Too much of a nutrient can harm or even kill plants
 Pesticide  A substance used to destroy insects or other organisms harmful to cultivated plants  Pests damage plant growth and leave them open to disease, but pesticides are also dangerous to humans. If you're using pesticides in your gardening, make sure that you are protecting yourself from them and cleaning all plants thoroughly
 pH  pH (potential of hydrogen) s a measurement scale of hydrogen ions that describes something as acidic or alkaline  pH is important because it affects the availability of nutrients to your plants. At a soil pH of 6.5, the highest number of nutrients are available for plant use.
 PPM  Parts per million - the concentration of any particles in a solution  Knowing the PPM lets you know if your nutrients are on track or not and will help you avoid over or underfeeding your plants
 Propagation  The process of creating new plants  Plant cells are "totipotent" or "totally potent." That means that every cell can reproduct more cells and grow into a new plant. Cool, right?
 Scrog Net  Scrog (screen of green) is a process to guide plants to grow vertically  If you're growing in a tent or another small space, a scrog tent can help you maximize that vertical space
 Secondary Nutrient  Plant nutrients needed in moderate amounts - calcium, magnesium, sulphur

 Anything that you're growing will need these nutrients!

 Soluble  Soluble refers to the ability of a substance to be dissolved, generally in water

 Plant roots can only absorb nutrients that are dissolved - they can't take in solid nutrients. That makes the ability of those nutrients to be absorbed very important.

 Terpenes Compounds responsible for the way plants smell and taste

 Some terpenes play a protective role in the plant while others act as part of the plant's immune system. Terpenes can have specific benefits in a human body as well.  Here is a link to our newest blog on our sister site:
