    double potting: a two-pot transplanting technique that minimizes root disturbance
    drainage: to empty soil of excess water. Good drainage: water passes through soil, evenly promoting plant growth. Bad drainage: drainage water stands in soil, actually drowning roots.
    drip (irrigation) system: efficient watering system that employs a main hose with small water emitters (tiny holes) which meter out water one drop at a time at regular, frequent intervals
    drip line: a line around a plant directly under its outermost branch tips: Roots seldom grow beyond the drip line.
    dry ice: cold, white, solid substance formed when CO 2 is compressed and cooled: Dry ice changes into CO 2 gas at room temperatures.

The drip line.
    dry soil pocket: small portion of soil that remains dry after watering: Dry soil pockets may be remedied by adding a wetting agent (soap) to water and/or waiting 15 minutes between waterings.
    dry well: drain hole filled with rocks, to receive drainage water
    electrode: a solid electric conductor used to establish electrical arc between contacts at either end of an HID lamp
    elongate: to grow in length: Cannabis stretches from three inches to a foot when flowering is induced.
    embolism: bubble of air in the transpiration stream of a cutting; blocks uptake of water and nutrients
    emit: to give off, send out (as light or sound, etc.)
    embryo: a young plant, developing within the seed: In cannabis, an embryo is derived from a fertilized ovule.
    Encarsia formosa: a parasitic wasp that preys on whiteflies
    envelope: outer protective bulb or jacket of a lamp

    essential oils: volatile oils that give plants their characteristic odor or flavor; contained in the secreted resins of plants
    ethane methyl sulfonate: a mutagenic chemical that causes changes at the DNA level; induces genetic mutations

    F1 hybrid: heterozygous first filial generation
    F2: second filial generation, resulting from a cross between two F1 plants
    fan leaves: large, fan-like marijuana leaves: Fan leaves are usually low in potency.
    female: pistillate, ovule, seed producing
    fertilize: 1. to apply fertilizer (nutrients) to roots and foliage 2. to impregnate (unite) male pollen with female plant ovary
    fertilizer burn: overfertilization; first, leaf tips burn (turn brown), then leaves curl
    FIM pruning: acronym for “Fuck, I missed!” pruning method. See page 64 for more information.

    fuse box: electrical circuit box containing circuits controlled by fuses
    ganja: slang term for cannabis, from the Indian (Hindustani) word for marijuana
    gametes: a reproductive cell specialized for fertilization, having the haploid number of chromosomes: a mature pollen grain or ovule capable of fusing with a gamete of the opposite sex to produce the embryo
