18/6: Time normally associated with the vegetative stage of growth i.e. 18 hours of light
to 6 of darkness.
12/12: Timing used to initiate the flowering stage of the plant i.e. 12 hours light to 12
##/## - The first number refers to the number of hours the lights are ON, and second number refers to the number of hours the lights are OFF.
Abiotic stress - Non-living environmental factors such as frost, drought, excessive heat,
etc. that can have harmfvl effects on plants.
Abscisic Acid - Mediates stress tolerance responses in higher plants, is a key signal
compound that regulates stomatal aperture and, in concert with other plant signaling
compounds, is implicated in mediating responses to pathogens and wounding.
In seeds, ABA promotes seed development, embryo maturation, synthesis of storage
products (proteins and lipids), desiccation tolerance, is involved in maintenance of
dormancy (inhibition of germination), and apoptosis. As well, ABA affects plant
architecture, including root growth and morphology, and root-to-shoot ratios
Aeroponics - Is the growing of plants in a container in which the roots are suspended in a
nutrient mist rather than in a solution. The most popular container for aeroponics is an
enclosed A-frame constructed of styrofoam boards. The plants are placed in holes along
the sloped sides of the frame. The nutrient mist is delivered to the roots by a vaporizer or
by special attachments available with drip irrigation kits. The mist clings to the roots. Any
excess runs down the inside of the frame, is collected at the bottom, and is recycled back
to the nutrient reservoir.
Alternating Leaf - As the plant grows, in the begining, every leaf (that is not damaged)
will have another leaf growing from exactly 180 degrees around the stem. They grow in
pairs. When the plants mature, the leaves will grow one at a time. that is a leaf will pop
out on one side, then, up the stem/ btanch, another will grow. (ie; Alternating)
Auto-Flower (Strain) - An Auto-Flowering strain is a strain of cannabis that automatically
flowers when it reaches maturity. Meaning you don't have to Force Flower as you would
with other plants (ie; changing the light cycle to 12/12, thereby causing the plant to
flower, anticipating the onset of the fall, and then winter, seasons. Auto flower strains
will flower and live out their entire life cycle from sprout to harvest, under 24 hours of
constant light, eliminating the need for a timer. Though they WILL still flourish under
18/6, if the grower wants to allow the room to cool.
Auxins - are plant hormones governing many biological processes in higher plants such
as cell enlargement and division, differentiation of vascular tissue, apical dominance, root
initiation and signaling.
Bag Seed - A seed obtained from a bag of finished cannabis. (Usually the genetic strain of
the seed is unknown, which is why we call it a bagseed)
Ballast - Provides current and power to the light. Here it mostly refers to the above for
H.I.D. (high intensity discharge) lighting.
Blood Meal --This organic fertilizer is very high in nitrogen and is very soluble in water
(unlike most other dry organic fertilizers). It also contains plant growth regulators. All
this together means that its effect is strong and quick, but its power will only last a short
while, especially in wet weather. When applying blood meal, take care, as it will easily
burn a plant's leaves.
Buds - The reason this website exists! -The part of the flowering female plant that
contains high concentrations of THC and other psychoactive ingredients.
Bud Leaves - the small leaves that grow in the buds of the plant, usually covered in
trichomes when harvested.
Calyxes - "the usually green outer whorl of a flower consisting of sepals" -
Canopy - The top branches of a plant, usually shading the lower branches, except when
branch training methods are used. (See LST, SCROG, and SOG)
Cannabidiol (CBD) is NOT a byproduct of THC, it's a Cannabinoid in it's own right and
works in conjuction with THC to influence the start and duration of the high.
Cannabinol (CBN) is a byproduct of THC and is produced via THC degradion from
heat/air/light etc as you describe. It only has a maximum of about 10% THC content and
therefore adds little to the 'high' over and above making the user feel 'sleepy'.
Neither are responsible for the 'stoney' part of the high nor the 'psychoactive' affect the
THC has - that is produced soley by THC.
Canoe-ing? - When a plants leaves curl upwards into a V-Shape, usually caused by heat,
CFL - Meaning 'Compact Flouresent Light' AKA 'The Big Curly Bulb'. High Lumen output,
small, and power efficient lights. While not the MOST effective, they work very well for
their size and power consumption.
CFM - Cubic Feet per Minute. This describes the volume of air that is displaced in 1 minute
