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.

Organic Nutrients - Natural, earth derived nutrients.
pH - Measurement of Alkaline or Acid. Measured on a scale of 1 to 14. Water is considered neutral at PH 7. PH levels below 7 are classified as acidic, or "sour". Levels above 7 are basic, alkaline or "sweet". Most plants prefer a slightly acidic soil pH of 6.0 to 6.5.
pH Meter - Electronic devise to measure the pH.
pH Test Strips - Colored Test Strip Indicators to dip into the water and determine the pH.
pH Up - pH Down - Chemicals use to adjust the pH up or down.
Phloem- Nutrient moving tissue.
Photoperiod - The timing of the light period. The number of hours of light and darkness the plant gets. Usually shown as 18/6 = 18 hours of light, and 6 hours of darkness.
Photosynthesis - The plant using LIGHT absorbed by Chlorophyll to make food and sugars for food for the plant.
Pistil - ( Slang = the hairs) A hair looking growth from calyxes of a female plant, also a precursor to the buds themselves. Pistils start out white and turn to dark red to show maturity. In some books, and in Europe, Pistils and Stigmas are inter- changeable.
Pop, Popping - a seed when it first opens. Example: I soaked my seeds last night and they all popped.
Popcorn Buds - Very small round buds about the size of a marble that had no stem and are not dense.
PPM - Parts Per Million. A measurement of nutrients and additives in the water.
PPM Meter - An electronic devise to measure ppm.
Pre-Flower - The first sign of SEX, it is what you see first before you see the actual flower.
PYTHIUM - Root Rot The dying and decaying of the roots, commonly caused by too warm of water.
Reservoir - The water container or water tank.
Resin Glands - European term for Trichomes.
ReVegging, Re-Veg - After a Partial harvest of the larger buds, putting the plant back into the VEGGING Light Cycle to force the plant to continue to grow and then back to the 12/12 Flowering Cycle to grow the smaller buds larger.
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.
Sensimilla - Sensi Mexican for without seed or Virgin Pot. Slang is "Sensi".
It is the female buds or flowers that male pollen did not fertilize. Sensi is more potent in THC than fertilized pot with seeds.
Sex, "To Sex" " - The act of determining the gender of a plant by giving it a photoperiod of 12/12.
Shock - The mental or emotional state of a plant that has been abused or neglected.
Stamen -The male reproductive part of a plant composed of two parts, the filament and the anther. It is the penis of the male plant.
Stigma - The sticky tip of a Pistil or another name for the Pistil..
Stomata - Opening in the epidermis (skin) of a leaf which permit oxygen exchange with the air.
Strain, Strains - A Variety or Species, or genetics. A kind or type of plant. Popular strains are Northern Lights, White Widow, Mazar, Bubble Gum, Panama Red, Gold Bud, Skunk, etc
Stress - Any bad, wrong, unhealthy attention that the plant receives; Heat, too strong of light, over watering, over feeding, underfeeding, and coldness are examples of Stress. Stress slows growth.
Stretching - The plant REACHING and GROWING toward the light source.
Substrate - The source or base used to start the seed or sprout in.
Sun Leaves, or the Fan Leaves - They are the larger leaves that grow lower on the plant, and are the food makers for the plant. Fan leaves are very necessary and healthy fan leaves should never be cut off. They contain very little THC but are a good source of CBD/CBN. Most growers save them to make oil.
Super Cropping - Steps and procedures to stress (torture) the plant to increase yield, THC or trichomes the last week of Flowering, before harvest.
TDS - Total Dissolved Solids or Total Dissolved Salts. (See RNC) Relates to the eaten or absorbed nutrients and the uneaten nutrients that become toxins to the plants.
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.
Trim Leaves - the small leaves that grow out of the buds of the plant, usually covered in trichomes. Trim Leaves are also called Bud Leaves. Most growers save them for making HASH and Oil.
Vegging Cycle, Vegetative Cycle, (Grow Cycle) - The Cycle of 18/6 or 24/7 Light to grow the baby plant to maturity and prepare for Flowering.
Ventilation - Circulating air in order to provide the plant with fresh air and/or to reduce the temperature in the grow area. Air movement also encourages strong stems.
Watts - A measure of the amount of electricity flowing through a wire. Watt hours measure the amount of watts used in one hour. A kilowatt/hour (KWH) is 1000 watt/hours.
Wet Paper Towel Method - A method of using a wet papertowel to germinate seeds.
Xylem - Water- transferring leaf tissue.
you all are doin awesome in helping all the " newbies " .. as i am one roseman has helped alot i think this is very helpful thx for your time in helping to educate me , and any one else not ashamed to admit it
