I am not very knowledgable in Soil Growing so I did not include Soil Growing Terms.
I do hope this especially helps the new growers and new Deep Water Culture.
18/6: Time in Vegging or Growing Cycle 18 hours of light to 6 of darkness.
12/12: Time in Bloom of Flowering Cycle. 12 hours light and 12 hours darkness.
24/7 : Time in Vegging or Growing Cycle 24 hours of light in 7 days a week.
420 - Enjoying Marijuana, Being Identified or Associated with Marijuana.
Aeroponics - growing in a reservoir in which the roots are suspended in a nutrient mist or fog instead of in the water and nutrient solution. The Spray or Mist sticks to the roots, keeping them from dying out. Any extra water runs down the inside of the reservoir or container, collects at the bottom, and is recycled back to the nutrient reservoir again.
Air Bath - Allowing the roots to dangle in the air out of the water for a short period of time.
Air Stones - Air Diffusers - Devices commonly used in aquariums, and used in hydroponic reservoirs to add air or oxygen to the water.
Alternating Leaves- Alternating Nodes - as the plant first grows, every leaf will have another leaf growing exactly across from the other leaf. They grow in pairs. When the plant becomes an adult, a mature plant, the leaves will grow one at a time and be staggered. A leaf will pop out on one side, then, up the stem a half inch, another leaf will grow.
Ballast - Provides electricity to the HID, High Intensity Discharge light.
Bracts - Another word for calyxes, used in Europe.
Deep Water Culture - A Marijuana grower that uses Bubbles or Deep Water Culture or DWC.
Deep Water Culture - Slang for growing Hydroponically in Bubbles. A registered copyrighted word, it is the Hydroponic process of growing DWC with additional feeder tubes fed from a submersible water pump in the reservoir tank to each grow cup, producing a rapid growth.
Buds - The good parts! The desired parts of the plant for smoking and ingesting. The part of the female plant that contains high concentrations of THC. Buds are a lump or clump or cluster of very tight flowers.
Bud Leaves - the small leaves that grow out of the buds of the plant, usually covered in trichomes. Bud Leaves are also called Trim Leaves. Most growers save them for making HASH and Oil.
Buffers - Chemicals you add to the water to stabilize the pH, commonly made for aquariums.

CFM - Cubic Feet per Minute - The measured volume of air that is displaced in one minute. It is how vented air or the performance of the fan is measured.
Chlorophyll - the green pigment in leaves. Chlorophyll pigment is produced in the chloroplasts of leaf, stem and flower cells. Chlorophyll captures the sun's energy which is used to manufacture sugar from carbon dioxide and water. Chlorophylls are constantly being "used up" and thus are continually manufacture by the plant, provided the environmental conditions are appropriate. Chlorophyll gives the green taste.
Cloning - The process of duplicating female plants. It is simple "Rooting" a small branch from a female plant.

Cure, Curing - Preparing harvested buds for storage. Curing is a biological process of allowing the SUGARS and STARCHES to change into something MORE pleasant to the taste and smell. Normally the SUGARS and STARCHES taste HARSH and not so pleasant. To grow, Plants need SUGARS that convert into starches from Fertilizers and sunlight. Curing also removes alot of chlorophyll or the chlorophyll taste that is sort of a grassy leafy medicine chemical taste and leaves a sweet tasty pleasant taste.
Also, we cure pot to avoid MOLD that can come within 30 days AFTER Drying.

Floros, Flourescents - Light Bulbs with a separate or built in STARTER and BALLAST. They come in 18, 36 and 48 inch long tubes, or can be Compacts, Twisty bulbs and Circle bulbs. They are desirable for using less electricity and being cooler, but they do not penetrate as deep as HID Lights and are not as efficient as HID lights.
HID Lights use more electricity and are hotter.

LOLLIPOPPING - The cutting off of the lower third of a plant's growth so that the plant's energy goes to the upper 2/3s of the plant to make larger buds. They say it makes the plant look like a lollipop. (THIS PROCESS IS LAUGHED AT BY MANY GROWERS AS NOT BEING SCIENTIFIC OR FACTUAL)
Lumen - How we measured LIGHT SEEN by our eyes. One lumen is equal to the amount of light emitted by one candle that falls on one square foot of surface, one foot away.
LST - Low-Stress Training, the technique of controlling the branches to reduce plant height, and expose certain branches to light. LST is used in small grow areas with limited height space. This is accomplished by bending them over sideways and tying them over. Also by using wires or screens or nettings to control the Vertical height growth.

Nutritional Lockout - Allow me to GIVE you a simplified definition of NUTRIONAL LOCKOUT. Can you imagine sitting a plate before a child at dinner time, with his most favorite food, hot dogs, ketchup and french fries? But also on the plate is a major portion of steamed broccoli, which he is just not fond of and insists on nibbling on. Now imagine telling that child, "you can not eat the hot dog and fries if you do not eat all the broccoli too". NUTRITIONAL LOCKOUT is when the child responds with "well then, I just won't eat!"

RNC - Relationship (Ratio) of Nutrient Concentrate; the uneaten nutrients.
R O Water - Reverse Osmosis Water - Filtered water with all the minerals removed.
Rockwool - Rockwool Cube Blocks or slabs or cubes of rock wool are used extensively by hydroponic growers. Rock wool typically has an alkaline pH, is sterile and chemically inert. Rockwool is a man-made mineral fiber. The vast majority of rockwool used in the world is used for insulation purposes much like fiberglass. It holds water well and is the best substrate that can be used in Hydroponic growing. Rockwool is made by melting a combination of rock and sand and then spinning the mixture to make fibers which are formed into different shapes and sizes. The process is very similar to making cotton candy.
Root Zone - the area around the bottom base of the plant where the roots first appear.
Ruderalis - If it is not Sativa or Indica, it is Ruderalis. Think Thai Sticks. It is a much smaller strain that is more difficult to grow and producers much smaller buds and much smaller plants.
Sativa - Is a strain that has long, slender, finger-like leaves. It grows much taller than Indica and growers slower too. The Flowering Cycle of Sativa is much longer than Indica Strains. It is also more difficult to grow indoors. It is a heady high, and makes you feel creative and energetic too.
Scissor Hash - The sticky kief or trichomes that stick to the scissor while ypu are harvesting the buds.
SOG - "Screen Of Green" - Your grow is appraised or valued by the Tops and not by the entire plant or garden. The purpose of SOG is to maximize the use of a smaller grow space and less lighting by training the new growth of a plant into a screen or mesh or netting.

THC - Tetrahydrocannabinol A compound obtained from cannabis that is the primary intoxicant in marijuana. The main psycho active ingredient in pot. This is what gets you HIGH.
Topping - Method used to increase yield and make more buds by trimming off the top new growth of each leaf top or end or tip of each branch.. Topping your plant causes two new leaf growths to grow back in place of the one that was cut off.
Topping Off - Replacing the water consumed that day that the plant drank.
Transpire - Transpiration - A plant sweating or giving off moisture.
Trichomes Trichs- Slang is "trichs" or "the crystals", or "the fairy dust", or "the ice" or "the sugar". In Europe, they are called "the Resin Glands". They are very microscopic penis shaped, or mushroom-shaped capitulate glands full of THC that form on the flowering buds and trim leaves.
