DRF
Dynamic Root Floating. A hydroponic technique based on the use of a low typhoon-proof greenhouse with a framework of piping, a ridged culture bed, concave panels, an aspirator, a nutrient level adjuster, a nutrient exchange box and a nutrient concentration controller. DRF technique makes possible the successful year-round production of leafy vegetables in tropical and subtropical areas.

DRIP AERATION
A hydroponic method wherein air pressure from a small air pump is used to percolate nutrient solution out through a ring of feeder tubing which encircles the plant.

DRIP SYSTEM

A product that destroys or inhibits fungus.

FUNGUS: DAMPING OFF FUNGUS
Disease that attacks young seedlings and cuttings causing stem to rot at base: Overwatering is the main cause of damping-off.

G

GEOLITE
One of several brand names/varieties of clay aggregate medium (also known as LECA for light expanded clay aggregate). It is a lightweight, porous substrate with excellent aeration. Because it does not really wick water effectively, Geolite and other LECA mediums are favorites in ebb-and-flow and drip hydroponic systems.

GERMINATION
The process of causing the initiation and development of a plant from seed.

H

HALOGEN
Any of the elements flowering, chlorine, bromine, iodine and astatine existing in a free state: Halogens are in the arc tube of a halide lamp.

HARDEN-OFF
To gradually acclimatize a plant to a more harsh environment. A seedling must be hardened-off before planting outdoors.

HID
High Intensity Discharge. These are lights that are commonly used in greenhouse and indoor gardening application.

HORMONE
Chemical substance that controls the growth and development of a plant. Root-inducing hormones help cuttings root.

HYBRID
An offspring from two plants of different breeds, variety or genetic make-up.

HYDRATED LIME
Instantly soluble lime, used to raise or lower pH.

HYGROMETER
Instrument for measuring relative humidity in the atmosphere: A hygrometer will save time, frustration and money.

I

INTENSITY
The magnitude of light energy per unit: Intensity diminishes the farther away from the source.

J

Jacket
Protective outer bulb or envelope of lamp.

Jiffy 7 pellet
Compressed peat moss wrapped in an expandable plastic casing; When moistened, a Jiffy 7 pellet expands into a small pot that is used to start seeds or cuttings.
