L | M A Air flow - It is important to get a good flow of air circulating through any indoor crop. Extractor fans are used to remove air that is warm and stale, as well as some of the odour. This air needs to be replaced and the best entry point is around the bottom of the plants, so this fresh air can circulate up through the leaves and out at the top. B Bifta - Slang term for a cigarette made of marijuana. Blow - A slang term for marijuana. C Calcium - [C] Calcium is essential for plant growth, cell division and enlargement. It is a component of cell membranes and is important for developing the root system, shoot tips and storage organs. Calcium aids in pollen development and help plants to retain their foliage. Cannabis - A drug produced in various forms from the dried leaves and flowers of the hemp plant, smoked or chewed. Also, the hemp plant, especially when grown as a source of cannabis. Latin name: Cannabis sativa. Smoking of the buds and leaves causes a cerebral effect often referred to as being "stoned", or "high", and is used recreationally, for relaxation and for certain medicinal conditions. Cannaboids - CBD - [cannabidiol] Indica's higher CBD than THC equals a much heavier, sleepy type of high. Indica plants have a very stony high that is relaxing and can help different medical problems. CBN - [cannabinol] This is produced when the thc degrades (the bud goes off) and is undesirable. Clone - A clone is basically a cutting from another plant. By this technique, one can ensure that the genetic qualities of a mother plant are reproduced; hence the name cloning. The only disadvantage is that clones tend to grow less vigorously than plants started from seeds. Begin from seed and choose your best plant. The best shoots for cutting are side shoots on the lower part of the plant, as these will root faster than older parts of the plant. Coconut Fibre - Coconut fibre is a versatile grow media that can be used in soil and hydroponics because it is biodegradable. Coconut fibre is also very durable, resistant to rot and is made of compressed, shredded coconut shell fibres and comes in various forms. It is sometimes used in soil cultivation in place of peat moss, while others use it as mulch. Some hydroponics cultivators top off their rockwool grow media with shredded coconut fiber for better moisture retention. Brick or cubed coconut fiber is best suited for plant propagation while the shredded form works better in ebb & flow and drip systems. Coconut fibre also retains its original shape fairly well and can be reused in hydroponics applications or used for improving soil. Cross - A cross is the offspring or generation of 2 similar geno-types. Curing - Curing or drying is an important part of the process, to be sure that your cannabis reaches its best. By drying slowly, you make the buds more pleasant and tasty to smoke. This process can take about two weeks and the buds keep their delicious, sweet aroma and taste. During drying, there are chemical changes that happen, which will increase the active ingredients. The desired drying area needs to be around room temperature (low 70F) and in darkness. Ventilation and air circulation are also important, so as to avoid mould problems. D Dope - Slang term for marijuana. E EC - [Electric Conductivity] EC is an important measure of total solute concentration (salinity level) of a solution. High salinity in the solution decreases the availability of water to the roots of plants and prevent nutrient uptake and overall growth performance. The osmotic potential near the root, which depends on the nutrient concentration in the solution, is used to control the plant's growth, development and fruit quality. The EC can be completely controlled by the Gardener. Commercial growers make daily decisions about their EC settings depending on the condition of the crop and on light levels. A good understanding of EC level is essential for maximum crop performance. F F1 - The term "F1" means the "first filial generation" or "first generation offspring" of a cross between 2 different genotypes (seed lines). While F1 types are generally uniform, they do not breed true, like IBL's and regional land races. Fan Leaf - A fan leaf is a large leaf that often shades lower buds from the light they need to grow well. Fan leaves may be prudently removed to allow light to pass through the plant. Female Plant - A female flower has a small green seed pod with two fuzzy V-shaped hairs sticking out of it. The hairs, called stigmas, are white but they can be other colours, depending on the strain you are growing. The flowers build up during flowering to form the thick clusters, generally called buds. The female is usually shorter and bushier than male plants. Between 7 to 21 days there is a change from growing to flowering when placed on a 12/12 flowering light cycle. If you look near the stem and leaf joints on your plants, you will see the change. Flowering Period - The flowering period relates to the second stage in the life of a cannabis plant. In the wild, marijuana plants change from vegetative growth to flowering when it detects a shortening in daylight hours. Indoor grow systems can be manipulated to a perfect 12 hours on, 12 hours off to stimulate bud formation. Most varieties of cannabis will need 12 hours of constant, uninterrupted, total darkness every day. The dark period needs to be at a regular time each day. It is possible to use a timer switch when using lamps. Interrupting the dark period by looking in the grow area or letting outside light in during the dark period will delay flowering, stress your plants and even promote sexual deviation; so instead of females, they change to hermaphrodites (a plant that is part male and part female). G Ganja - Slang word for cannabis. H Hermaphrodites - A plant that is part male and part female, usually brought about through stress or confusion due to fluctuating light periods. High Pressure Sodium - High Pressure Sodium [HPS]lights are strong in the red spectrum of light and are good for flowering. While the lamps come with different shades or reflectors, sodium bulbs in horizontal shades/reflectors, work best for flowering. It is advisable to give 30 to 60 watts of light for each sq foot of growing space. Be aware that lights do get hot and can burn plants that get too near. However, the closer the light is to the plants, the better for the plant, as the light is stronger and more intense; thus highly beneficial to the buds. In general keep 400w lights 30-45 cm above plants and 1000w lights 45 to 75 cm above plants. Hybrid - A hybrid is the offspring of two dissimilar genotypes bred to each other. Hydroponics - Hydroponics is defined as a technique for growing plants without soil in a nutrient and oxygen rich solution or medium. It is often referred to as aquaculture or soil-less culture. Hydroponics was usually reserved for commercial growers but home gardner's are increasingly showing interest in the technique. I IBL - An IBL is an inbred or stable seed-line that was bred or made by a breeder, by crossing different genotypes (seed-lines) to each other and then crossing successive generations of their offspring, until uniformity of appearance and strength is achieved. Indica - Indica plants originate from northern latitudes. Indica's higher CBD than THC equals a much heavier, sleepy type of high. Indica plants have a very stony high that is relaxing and can help different medical problems. Effective for anxiety, pain, nausea, appetite stimulation, sleep, muscle spasms and tremors, among other symptoms. The Sativa strains are MORE of a stimulant, effective in appetite stimulation, relieving depression, migraines, pain and nausea. K Kaya - Slang term for marijuana. L Land Race Strain - A land race strain is one that has been grown for hundreds or thousands of years in the country of origin. M Magnesium - [M] Magnesium occurs in chlorophyll and is also an activator of enzymes. Male Plant - Marijuana plants display their sex, often around the period of transition between growth and flowering. In the early stages, the male flowers look like small bunches of mini green bananas or grapes. These bunches are the pollen sacs. Once these sacs open, the tepals push back and release their pollen. There is very little THC in male flowers and their pollen has been known to make people ill. Males are taller, so they can easily shower their pollen over the females. They are less leafy and are often thin and stringy, unlike their female counterparts. Males start flowering between 7 to 14 days when there is a change in the light cycle and need removing because one or two males can produce enough pollen to seed a whole crop of females, thus reducing the females' potency and ruining your good work. Metal Halide Lamps - Metal Halide lamps are used as an artificial light source for growing plants indoors, having a "white" colour which makes a good approximation for daylight. They are usually used during a plant's growth phase because it's spectrum provides good growth rate and smaller compact plants. Metal Halide Lamps provide high system efficiency (up to 100 lumens/watt) compared to Mercury Vapor, fluorescent and incandescent lights. They last for 10,000 to 15,000 hours, having a shorter lifetime than high pressure sodium lamps. Mould - About 75% of the weight of fresh cut cannabis is water and mould can ruin a plant overnight during the drying process. To avoid mould problems ensure there is good ventilation and air circulation. However, if you do get a problem of mould, just separate the moldy plant from the rest, trim off the mould and dry the plant quickly. N Nitrogen - [N] Nitrogen is important for normal plant development. Nitrogen is a component of amino acids, a protein which include nucleic acids, enzymes, light-harvesting pigment and chlorophyll. Nitrogen promotes plant growth and dense, bright foliage. P Perlite - Perlite is a soil-less medium. Expanded perlite can weigh as little as 2 pounds per cubic foot (32 kg/m3) making it suitable for numerous applications such as horticultural and industrial. Perlite is a form of natural glass and it is chemically inert with a pH of approximately 7. pH - [potential Hydrogen] pH is an index of Hydrogen's chemical activity in a solution and expresses the degree of acidity of a substance using a Log Scale Unit of Measure. pH scale goes from 0 to 14 with seven being the neutral zone. Anything above is base or below is acidic with 0 being the most acidic and 14 the most base. Pure water is approximately a pH of 7 or neutral. Phosphorus - [P] Phosphorus commonly misspelled "Phosphorous" is an essential part of the enzyme responsible for aiding crops to fix light energy. Nucleic acids carries genetic information and is important in stimulating root development. Phosphorus is an integral part of nucleic acids. Photoperiod - The period of light in a plant's day. For indoor growing purposes a photoperiod of 18 hours a day is recommended. To initiate flowering the photoperiod is shortened to 12 hours of light a day. Photosynthesis - Photosynthesis is the building of compounds such as carbohydrates, using light energy, water and CO2 (carbon dioxide), releasing oxygen as a by-product. With no light at all, a plant's leaves soon yellow and eventually the plant dies. With the right spectrum and intensity of light, photosynthesis is accelerated and growth is rapid. Pistils - a carpel or group of fused carpels forming the female reproductive part of a flower and including the ovary, style, and stigma. Pot - Slang term for marijuana. Potassium - [K] Potassium assist in the processes which ensure carbon assimilation and the transport of photosynthates through the plant for storage of sugars and proteins, and growth. Potassium is important for water regulation and intake. Sufficient potassium help plants resist frost, drought and certain diseases. R Resin - Rockwool
- Rockwool is spun glass wool made from volcanic rocks, hence the
name "Rockwool". Rockwool comes in various shapes and
sizes and is a popular grow media for hydroponics. Loved for its
convenience and versatility, this media is excellent at retaining
oxygen and water. Rockwool will also offer great structural support
for plants and is a solid choice for drip, ebb & flow and NFT
systems. S Sativa - Sativa plants originally come from the tropics. It has generally higher THC (tetrahydrocannibinol) than CBD (cannabidiol), which means it provides a more cerebral, soaring type of high; more energetic thus stimulating brain activity and may produce hallucinations. Flavours range from earthy to sweet and fruity. Skunk - Spliff - Slang term for a cigarette made of marijuana. Sulphur - [S] Sulphur forms part of two important amino acids which are part of the many building blocks of protein. Sulphur is found in B1 vitamin and several other enzymes. T THC - [tetrahydrocannibinol] Sativa has generally higher THC (tetrahydrocannibinol) than CBD (cannabidiol), which means it provides a more cerebral, soaring type of high; more energetic thus stimulating brain activity and may produce hallucinations. V Vermiculite - Vermiculite is a soil-less medium, which does not provide nutrients to plants. Soil-less media are almost neutral in pH level and will not interfere with nutrient solution. Used alone or as a combination, these Soil-less media are great for crops because vermiculite retains moisture while perlite provides adequate oxygenation and will not disturb a delicate root system. W Weed - Slang term for marijuana. Z © seedselecta.co.uk 2004 If
