CALYX
This is the actual "nugget" or "bud" of the plant; many many calyxes make up an actual smokeable nugget. This is also the female reproductory part of the plant, containing the ovule and pistils
CBC

DRIP SYSTEM
A hydroponic cultivation method in which MJ roots grow in a very porous substance, with nutrient-enriched water being continually "dripped" down the medium
DWC
Stands for "Deep Water Culture." The hydroponic cultivating method of suspending MJ plants' roots into large reservoirs of water

EC
Stands for "electrolytic conductivity." EC is the measurement of the conductivity of a solution (amount of minerals in the solution)
1.0 EC approx. equals 1000 ppm
FLOWERING
The time period in which a plant takes on sex characteristics; either budding (female) or creating pollen sacs (male)
FLUSH
The act of using only water during the last few days/weeks of flower, thus "flushing" away any chemicals/nutrients in the MJ, allowing for a smoother and tastier smoke

GERMINATE
the process of getting your seeds to pop out and come to the surface.
GH
Stands for "General Hydroponic." This is a popular brand of nutrients for hydroponics, and there are three sub varieties of GH nutes; Grow, Micro, and Bloom (expressed frequently as 10-10-10, or 10 mL "grow" per gallon, 10 mL "Micro" per gallon, and 10 mL "Bloom" per gallon of water)
HEMAPHRODITE
A cannabis plant containing both male and female sex traits.
HID
Stands for "High Intensity Discharge." As the name indicates, a lot more light intensity than your common incandescent light bulb or fluorescent bulb
HPS
Stands for "High Pressure Sodium." This is an HID bulb, the most popular in cultivation, due to its immense red-spectrum of light, crucial for bud production
HUMIDITY DOME
something you would place over then cuttings or seedlings to retain the humidity.
HYPOXIA
A term used for a lack of oxygen
IBL
Stands for "In-Bred Line." Pertaining to the stability of a strain, an IBL is the term given to cannabis that has been breeded extensively to show complete uniformity in its genetics. Northern Lights is an example of an IBL
INDICA
The species of cannabis (cannabis indica), differing from cannabis sativa. Indica strains are characterized by shorter, bushier plants, with lower flowering times and denser buds. Also, Indicas seem to have more of a "stoned" affect, making one lethargic or couch-locked.
LAND RACE
Generally referring to a species that is native flora, adapted to its particular region and climate. Landrace strains are natural IBLs. An example would be Afghani
LEO
Law enforcement officers.
MACRO
A type of camera shot taken by a digital camera; extreme close-ups.
MH
Stands for "Metal Halide." An HID bulb, MH's are regarded in the same league as an HPS, but contains more blue spectrum, crucial to the vegetative stage
NECROSIS
dying or dead spots on a plants leaves. Usually a brown or rust colored spot. Many problems give this reaction. Some of the most common would be over watering, over fertilizing, nutrient lockup (toxic soil), lack of magnesium.
NODE
The place on the stalk at which the foliage grows from, usually in sets of two fan leaves in MJ
N-P-K
Stands for "Nitrogen-Phosphorus-Potassium." These are the three minerals/nutrients essential to cannabis for survival
NUTE LOCK
when the plant stops taken in nutrients because of too much nutrient or 'over fert', causing salt build up around the root mass. A flush will correct this. Too little is better than too much remember.
PAR
Photosynthetically Active Radiation. This is the measurement used in quantifying the amount of light a specific bulb gives out available for photosynthesis.
PETIOLE
The stem of a fan leave, this attaches in turn to the stalk of the plant
pH
Measures the amount of acid/base in a substance. Neutral is a pH of 7.0; below 7 is acidic, above 7 is basic.
PHENOTYPE or PHENO
size, style, color, branching or any other ways a plant can characterized/categorized. i.e. a tall phenotype; a heavy stalked pheno; a blueberry smelling phenotype.
PHYLLOTAXY
the pattern of leaves growing from a stem.
PISTIL
The female sex trait of cannabis, pistils are the white "hairs" that later turn orange, red, and even pink hues when a plant is mature
POLYPLOID
MJ mutation in which more than two sets of fan leaves grow per node having multiple sets of chromosomes in one cell.
POWERHEAD
used in DWC set-ups, a powerhead is any machine used to create constant current in the water, allowing for aeration of the roots
PPF PAR
Photosynthetic Photon Flux PAR, which refers to a process which actually counts the number of photons falling per second on one square meter of surface.
PPM
Stands for "Parts Per Million." PPM is the way in which to measure the concentration of a solute in a solvent (concentration of something dissolved in a liquid)
RADIANT FLUX
The amount of energy a light gives out per unit time. The standard unit of this is the Watt
R.O. WATER
Stands for "Reverse Osmosis." Reverse osmosis employs a semipermeable membrane that removes not only particles but also an extremely high percentage of dissolved contaminants-molecule by molecule- from raw tap water. Can cost anywhere upwards of Ž£100 for home-models, but brings ppm under 100 and a pH smack dab on 7.0
ROCK WOOL
A typical medium in which MJ is grown, characterized by its porousness for hydroponic set-ups
SATIVA
a species of cannabis characterized as tall and lanky, with sparcer buds that are less dense in comparison to an Indica. Conversely, most cannabis connoisseurs prefer the energetic, clear, psychoactive high associated to Sativas compared to an Indica
SCROG
Stands for "Screen of Green." The practice of placing a screen a certain height above the MJ plants, and then training each MJ shoot to go through a different hole in the screen. What this accomplishes is that, theoretically, all the buds produced will be uniform (same height and potency), since the light has equal penetration to top and lower buds. Typically used in small-cabinent set ups for optimal yield per watt of light
SENSIMILLIA
An MJ plant which contains no seeds for easy smoking, not introduced until the 70's
SOG
Stands for "Sea of Green." The method of placing several small clones into flower immediately, producing several small plants on a short time scale
SUPERCROPPING
a method of pruning a plants growth to cause its lower branches to be of uniform height with the main cola and upper branches. A very similar look to a candleabra or wine glass. This is done by trimming off all the taller leads of the plant, until the lower portion has caught up.
TDS
Stands for "Total Dissolved Solids." Measures the total amount of ALL minerals/nutes/chemical particals dissolved in water (usually measured in PPM or EC)
THC
tetrahydrocannabinol. This is the primary psychoactive influence of marijuana
TRICHOME
This is the resin that covers a calyx, the actual THC gland
VEGETATIVE
The stage in which an MJ plant is growing new foliage, but not showing sex traits yet
WHORLED PHYLOTAXY
MJ trait characterized by fan leaves being deformed in such a way that they kinda whirl in a circular type of pattern
YPF PAR
Yield Photon Flux PAR which goes one step further than PPF PAR in that it takes into account not only the photons but also how effectively they are used by the plant. Since red light (or red photons) are used more effectively to induce a photosynthesis reaction, YPF PAR gives more weight to red photons based on the plant sensitivity curve.
