Humidity is the measure of the volume of water in the air at a given temperature. Higher humidity (>75%) can lead to slowed growth due to reduced evapotranspiration and can increase the potential for disease that favors high moisture, such as powdery mildew. A circulation fan in the growing room and frequent air exchanges can reduce the amount of humidity in the air which will maintain an ideal environment for plant growth. Low levels of humidity (<20%) can also reduce growth by reducing the amount of moisture around the leaves of the plant which creates a situation of water stress in the plant. Using evaporative cooling or adding a humidifier to your growing environment can increase the level of humidity in the air and maximize the plant’s osmotic potential.
Soilless media that has been biologically enhanced using an array of organic inputs.
A device that measures relative humidity.
Indole-3-Butyric Acid is an auxin or plant hormone used to initiate root development. Thought to be synthetic, it can also be derived from natural substances.

A solution or medium that is chemically non-reactive.
The dissolving or washing out of soluble salts from a grow medium or soil.
Malformation of a leaf due to under- or over-fertilization, over-watering or damage caused by insects or disease.

0.000000001 of a meter. Used as a scale to measure wavelength in the electromagnetic spectrum, which includes visible light.
A mineral that a plant can uptake and assimilate into its tissue; a plant food.
Leaf scorch that occurs from over-fertilization or application of excess salts, like nitrogen.
A difficult aspect of growing plants is how to deal with harmful insects and diseases. Pest problems can be dealt with by using clean plant stock, minimization of exposure to outside environments and monitoring consistently. If insects do make it into your environment, using beneficial insects to combat the harmful ones or spraying with a variety of products that are targeted is the last resort. Preventing disease is not always possible, but using clean plant stock, keeping the environment clean, and preventing environmental conditions that favor the disease are the best steps to take.
The conversion of light energy to chemical energy (carbohydrates) by plants, which usually occurs in their leaves.
Altering a plant into a desired form by cutting its leaves, stems, shoots, flowers or fruits.
A hydro system which circulates or “feeds” nutrient solution from a reservoir over and over again, until the reservoir is either “topped off” with additional nutrients or drained out completely and replenished. Ebb & flow (flood & drain) is the most common recirculating system in hydro, although NFT (nutrient film technique) and drip systems can also recirculate nutrient solution.
Tiny openings in the leaves of plants though which they take up nutrients, release water and take in CO2 (carbon dioxide.)
The temperature of a growing environment is crucial to maintain optimal growth and maximize the genetic potential of the plant. The ideal temperature will vary given the stage of growth and the type of plant being grown. During vegetative growth, plants are growing very rapidly and can tolerate higher temperatures than during fruiting and flowering. A typical safe range for vegetative plants is 75-80°F during the light (day) period and 55-60°F during the dark (night) period. For fruiting and flowering growth, the temperature range is 70-75°F during the day and 50-60°F during the night period. Monitoring the growing environment with a thermometer that has minimum and maximum temperature logging is a valuable tool to keep track of the fluctuation of temperature throughout the course of the day.
A large class of plant secondary metabolites that play a role in floral aroma and other plant processes, and are increasingly being studied for their medicinal qualities.
To prune or remove parts of plants to allow remaining plant, flowers or fruits to develop more fully.
To apply fertilizer or compost to the top of soil or grow media.
