Heavy smoking decreases sexual capability by damaging the tiny blood vessels in the penis. The use of marijuana and cocaine also can result in impotence.

A study done at Boston University showed that men who smoked one pack of cigarettes a day for five years were 15 percent more likely to develop clogging in the arteries that serve the penis, a situation that can cause impotence. In addition, heavy smoking decreases sexual capability by damaging the tiny blood vessels in the penis. The use of marijuana and cocaine also can result in impotence.

A recent study at the New England Research Institute in Watertown, Massachusetts, found that impotence was equally common among smokers and non-smokers in general. However, among men with certain health problems, those who smoked were much more likely to have potency problems. For example, 56 percent of smokers with heart disease were completely impotent compared with only 21 percent of non-smokers with the disease.

Alcohol intake decreases the bodys ability to produce testosterone. Research at Chicago Medical School revealed that drinking alcohol may cause the hormonal equivalent of menopause in men. Alcohol not only affects sexual function, but also helps set the stage for a heart attack and other dangerous conditions.

Alcoholism. Excessive alcohol consumption disrupts hormone levels and can lead to nerve damage. This type of impotence may be reversible or permanent depending on the severity of the nerve damage. Some clinical studies suggest about 25 percent of all alcoholics become impotent -- even after they stop drinking.

So smoke marijuana is much safe. I buy marijuana seeds, in particular i love serious seeds, and i plant them.

The world of marijuana trafficking once existed mostly in shady places where the right dealers hung out or in exotic locales such as Amsterdam. But technology, which has revolutionized almost every other aspect of our world, has changed that. Now, a simple Google search reveals a universe of online pot, including hundreds of Web sites offering to sell marijuana and paraphernalia such as bongs and marijuana seeds as well as free, detailed directions for growing marijuana. How many marijuana growers the Internet has instructed or how much marijuana changes hands online each year isn't known. But experts agree that the Internet has become the world's biggest head shop and that stemming that digital tide will be difficult for governments. Drug users "can obtain whatever they want (online) with more ease than in the conventional illicit street market," the International Narcotics Control Board, an arm of the United Nations, said in a news release in April. The board said serious steps must be taken if governments hope to control the Web-based drug trade. The European Union, citing increased European marijuana use during the past decade, adopted a resolution last July encouraging its members to crack down on marijuana cultivation and promotional Web sites.

I know a person with a very observant eye and a keen sense of the possible. One day we were walking through a commercial area where men were unloading boxes from a truck. 'Fred' asked to see the manager, and told him that he could improve the effi- ciency of the operation by 30 percent if he was paid $100. The manager agreed to pay if it worked. Fred showed the manager that the men were loading only two boxes on each truck, while, if the boxes were loaded sideways, the trucks could hold four. The man- ager reluctantly wrote a check.
On the way out, Fred said, "I can still cut unloading time by 30 percent for $50." The manager shook his head, but as we began to leave he called us back and agreed. Fred told him to increase the length of the platform on the hand trucks by attaching a board to them. The manager handed Fred a President Grant, shaking his head with an 'I should have known' look. A study of any operation will reveal many areas for improve- ment. Even seasoned experts can overlook fundamental principles. For example, take two gardens, "A" and "B", maintained by experienced cultivators:
Garden A is lit by two vertical 1000-watt metal halide (MH) lamps with wide reflectors on a rotating light mover. There is an aisle between the wall and the garden. The plants grow in 3-inch cups filled with expanded clay, placed in 9-inch tubes. They are irrigated by two constant-flow sprayers aimed at each cup.

Each plant in this growing tube is irrigated by 2 dripper-sprayers which keep the roots moist.
Garden B is lit by two horizontal high-pressure sodium (HPS) lamps and one 1000-watt MH lamp. The lamps' mover has three arms and the light circles the garden. The plants grow in five-gallon buckets, each outfitted with three 3-inch plastic cups filled with expanded clay pellets. Each cup is irrigated by a constant drip.

This garden uses 4 gallon recirculating drip containers.
Both gardens will lose yield because the growers neglected to apply some basic principles when setting up the grow rooms. Here are four ways to bring these gardens to full potential:
Maximize light distribution to the plants. Plants use light to power photosynthesis, the process by which carbon dioxide and water are turned into sugar and oxygen. The more light the plants receive, the more sugar is produced, and the faster they grow. Both Gardens A and B waste light. In garden A, as the horizontal lamps travel around, much of the light is used to illuminate the aisles around the perimeter. In garden B, the bottom of the vertical lamp hangs below the reflector and much of the light travels horizontal- ly across the room, hitting the walls.

In both grow rooms, the walls are covered with black plastic, which absorbs light and emits heat. Placing a reflec- tive curtain around the garden perimeter could increase the amount of light received by the plants by as much as 20 percent. Curtains can be hung from the ceiling or from rods. Moveable reflective panels can also be used. Panels can be made from 4' x 8' Styrofoam pieces coated in a reflective material. Most growers prefer Mylar, but aluminum foil, silvered gift wrap, aluminized greenhouse white paint and flat white paint all work.

Vertical lamps emit most light horizontally. To reflect light vertically to the plants, they require deeper relectors; these are too shallow so much light is lost to the wall.
Provide adequate support to each of the plants. When shaded, plants lose the energy they need for fast growth. If plants are properly supported, they won't shade each other. This ensures that each plant has the necessary light and space to grow to its full potential.

The plants in Garden A are supported with an appropri- ate bamboo stake, but the plants in Garden B have no support. Neighboring plants are crowding over onto one another, shading the canopies and lowering growth rate and yield. The problem can be solved in several ways. Each plant can be supported by a bamboo stake secured with twist ties to keep the central stem erect. Alternatively, a small cage, such as a tomato cage, can be placed around each cup. A third option is to run a small fence along the length of each tube, attaching the plant stem with twist-ties. Rows of strings can be hung from the ceiling or overhead rods and connected to the plants.

Focus light where it is needed most. Stretching can occur when plants crowd each other for canopy space. Lower parts of the plant tend to stretch as a higher ratio of infrared light, rather than direct red light, reaches the lower canopy. Light can be reflected back from the floor to target the lower plant sections. This unfil- tered light is higher in red, counteracting the stretching effects of the infrared light.

The floors of both gardens are covered with dull-colored plastic tarps, and because of the plant spacing, much of the light hits the floor. Covering the floor with white plastic, Mylar or bright white posterboard, increases the amount of light received by the plants, and prevents stretch- ing by targeting the lower canopy.

Use CO2 to increase yield. The addition of a CO2 source can dramatically increase yield. Photosynthesis uses light to power a complex reaction in which hydrogen (H), carbon (C) and oxygen (0), from water (H20), and carbon dioxide (C02) combine to form sugar (C6H1206). The ambient level of CO2 in air is about 400 parts per million. In a closed environment under bright light, the plants quickly lower the CO2 levels as the 0 levels increase. When levels of CO2 go down to 200 ppm, photosynthesis stops.

Plant growth increases in a direct ratio to CO2 levels until another limiting factor (usually light) is encountered. Indoors, with bright lights, plants can use 1000 to 1500 ppm CO2. This is most easily supplied using a CO2 tank and regulator. Some of these regulators are time based, others work in conjunction with the ventilation; the most sophisticated measure the amount of CO2 in the air. Plants grow much faster, and produce heavier yields, when they receive CO2-enriched air right up until the last two weeks of flowering.

Before the pollen bags are used, the seed parent information is added to the pollen parent data. Included is the number of the seed parent, the date of pollination, and any comments about the phenotypes of both parents. Also, for each of the selected pistillate clusters, a tag containing the same information is made and secured to the limb below the closure of the bag. A warm, windless evening is chosen for pollination so the pollen tube has time to grow before sunrise. After removing most of the shade leaves from the tips of the limbs to be pollinated, the pollen is tapped away from the mouth of the bag. The bag is then carefully opened and slipped over two inverted limb tips, taking care not to release any pollen, and tied securely with an expandable band. The bag is shaken vigorously, so the pollen will be evenly dispersed throughout the bag, facilitating complete pollination. Fresh bags are sometimes used, either charged with pollen prior to being placed over the limb tip, or injected with pollen, using a large syringe or atomizer, after the bag is placed. However, the risk of accidental pollination with injection is higher. If only a small quantity of pollen is available it may be used more sparingly by diluting with a neutral powder such as flour before it is used. When pure pollen is used, many pollen grains may land on each pistil when only one is needed for fertilization. Diluted pollen will go further and still produce high fertilization rates. Diluting 1 part pollen with 10 to 100 parts flour is common. Powdered fungicides can also be used since this helps retard the growth of molds in the maturing, seeded, floral clusters.

Selection is greatly improved if one has a large sample to choose from! The best plant picked from a group of 10 has far less chance of being significantly different from its fellow seedlings than the best plant selected from a sample of 100,000. Burbank often made his initial selections of parents from samples of up to 500,000 seedlings. Difficulties arise for many breeders because they lack the space to keep enough examples of each strain to allow a significant selection. A Cannabis breeder's goals are restricted by the amount of space available. Formulating a well defined goal lowers the number of individuals needed to perform effective crosses. Another technique used by breeders since the time of Burbank is to make early selections. Seedling plants take up much less space than adults. Thousands of cannabis seeds can be germinated in a flat. A flat takes up the same space as a hundred 10-centimeter (4-inch) sprouts or six-teen 30-centimeter (12-inch) seedlings or one 60-centimeter (24-inch) juvenile. An adult plant can easily take up as much space as a hundred flats. Simple arithmetic shows that as many as 10,000 sprouts can be screened in the space required by each mature plant, provided enough seeds are available. Seeds of rare strains are quite valuable and exotic; however, careful selection applied to thousands of individuals, even of such common strains as those from Colombia or Mexico, may produce better offspring than plants from a rare strain where there is little or no opportunity for selection after germination. This does not mean that rare strains are not valuable, but careful selection is even more important to successful breeding. The random pollinations that produce the seeds in most imported marijuana assure a hybrid condition which results in great seed ling diversity. Distinctive plants are not hard to discover if the seedling sample is large enough.

One of the best solutions to energy verses output for most home gardeners is to use outdoor light for flowering and use continuous light indoors for germination and vegetative growth. This will take advantage of the natural light/dark cycle and cut your energy use in half compared to the same operation indoors. A small greenhouse can be built of Filon fiberglass or PVC sheets that is innocuous and looks much like a storage shed or tool shed so it's not likely to raise suspicions.

In fact, a large shed of metal or plywood can be modified with a luminous roof of PVC, glass, fiberglass or plastic sheet, and some strains that do not require a great deal of light will grow well. Such a shed will discourage fly-by sightings and keep your business your own! It also allows you to keep out rats and gophers, keeps out the neighbor kids, and can be easily locked up. It will also give you an opportunity to actually plant in the ground if you desire, and this is the best way to avoid root-bound plants (if your not using hydroponics), and get bigger harvests.

In winter, indoor space is used to start new seedlings or cuttings to be placed outside in the spring, using natural sunlight to ripen the plants. This routine will provide at least 3 outdoor/greenhouse harvests per year. If more space is available to constantly be starting indoors and flowering 2nd harvest plants outdoors, harvests are possible every 60 days in many areas, with a small indoor harvest in the winter as a possibility as well.

The basic strategy of year round production is to understand the plant has two growth cycles. At germination the plant enters into a vegetative state and will be able to use all the continuous light you can give it. This means there is no dark cycle required. The plant will photosynthesis constantly and grow faster than it would outdoors with long evenings. Photosynthesis stops during dark periods and the plant uses sugars produced to build during the evening. This is not a requirement and the plant will grow faster at this stage with continuous photosynthesis (constant light).

Once the plant is 12-18" tall, weather permitting, it can be forced to start flowering by placing it outside in the Spring or Fall. (For Summer outdoor flowering, the night must be artificially lengthened in the greenhouse to "force" the plants to flower. See FLOWERING chapter.)

Moving the plants to 10-13 hour light periods (moving it outside) with uninterrupted darkness (no bright lights nearby) will force the plant to flower. It will ripen and be 2-3' when ready to harvest. When a plant is moved from continuous indoor light to a 10-13 hour day outside, it will start to flower in anticipation of oncoming winter. Vegetative starts moved outside March 1st, will be ripe by May 1. Vegetative starts moved outside on May 1 will be ripe by July 1. Starts moved outside Sept 1 are picked by Nov. 1st. In Winter, operations are moved indoors and a crop is planted for seed in anticipation of planting outdoors the next summer, or just for some extra winter stash.

Keep in mind that the "man" is looking for plants in the Sept./Oct./Nov. time-frame, and may never notice plants placed outside to flower in April. Be smart, make your big harvest in May, not October!

Marijuana likes lots of food, but you can do damage to the plants if you are too zealous. Some fertilizers can burn a plant and damage its roots if used in to high a concentration. Most commercial soil will have enough nutrients in it to sustain the plant for about three weeks of growth so you don't need to worry about feeding your plant until the end of the third week. The most important thing to remember is to introduce the fertilizer concentration to the plant gradually. Start with a fairly diluted fertilizer solution and gradually increase the dosage. There are several good marijuana fertilizers on the commercial market, two of which are Rapid-Gro and Eco-Grow. Rapid-Gro has had widespread use in marijuana cultivation and is available in most parts of the United States. Eco-Grow is also especially good for marijuana since it contains an ingredient that keeps the soil from becoming acid. Most fertilizers cause a ph change in the soil. Adding fertilizer to the soil almost always results in a more acidic ph.

As time goes on, the amount of salts produced by the breakdown of fertilizers in the soil causes the soil to become increasingly acidic and eventually the concentration of these salts in the soil will stunt the plant and cause browning out of the foliage. Also, as the plant gets older its roots become less effective in bringing food to the leaves. To avoid the accumulation of these salts in your soil and to ensure that your plant is getting all of the food it needs you can begin leaf feeding your plant at the age of about 1.5 months. Dissolve the fertilizer in worm water and spray the mixture directly onto the foliage. The leaves absorb the fertilizer into their veins. If you want to continue to put fertilizer into the soil as well as leaf feeding, be sure not to overdose your plants.

Remember to increase the amount of food your plant receives gradually. Marijuana seems to be able to take as much fertilizer as you want to give it as long as it is introduced over a period of time. During the first three months or so, fertilize your plants every few days. As the rate of foliage growth slows down in the plant's preparation for blooming and seed production, the fertilizer intake of the plant should be slowed down as well. Never fertilize the plant just before you are going to harvest it since the fertilizer will encourage foliage production and slow down resin production. A word here about the most organic of fertilizers: worm castings. As you may know, worms are raised commercially for sale to gardeners. The breeders put the worms in organic compost mixtures and while the worms are reproducing they eat the organic matter and expel some of the best marijuana food around. After the worms have eaten all the organic matter in the compost, they are removed and sold and the remains are then sold as worm castings. These castings are so rich that you can grow marijuana in straight worm castings. This isn't really necessary however, and it is somewhat impractical since the castings are very expensive. If you can afford them you can, however, blend them in with your soil and they will make a very good organic fertilizer.

During vegetative growth the plants do best when the lights are kept on continuously. The plants do not need a "rest period". Some growers cut the expense of running high watt lamps 24 hours a day by turning them off for 1-6 hours. This is good both for clones and for marijuana seeds. However, costs other than light; such as rent, labor and risk remain fixed no matter what the light cycle is set at. This means that the garden is at maximum efficiency on a continuous light cycle. It actually costs growers more to grow an ounce of bud using an 18 hour cycle rather than a continuous one. Of course, meter considerations may dictate a break in the light period. The medium is kept moist continuously. Reservoir and wick hydroponic systems are self regulating: the medium draws water from the reservoir to maintain an even level of moisture. However, the reservoirs must be refilled periodically. Large plants use more water than small ones, so their reservoirs are checked more often. Once the reservoir is filled with water-nutrient mix added water is clear, pH adjusted and nutrient free.
Active hydroponic systems require irrigation two to four times a day. Warm gardens with large plants use more water than cool gardens with small plants. Reservoirs of re-circulating systems are refilled with pH adjusted nutrient-free water after each irrigation.
Plants growing in soil-type mixes also must be kept moist.
Small plants in a cool space may not need water for 4 or 5 days. Larger plants in a warm space may require irrigation daily, especially if they are kept in small containers.
When watering most growers irrigate until the containers drain. Cold water can shock the roots and hot water can burn them. They do best when irrigated with lukewarm water, in the low 70's.

1 Q. What is Marijuana?

A. "Marijuana" refers to the dried leaves and flowers of the cannabis plant [1], which contain the non-narcotic chemical THC at various potencies. It is smoked or eaten to produce the feeling of being "high." The different strains of this herb produce different sensual effects, ranging from sedative to stimulant.

2 Q. Who Uses Marijuana?

A. There is no simple profile of a typical marijuana user. It has been used for 1000s of years for medical, social, and religious reasons and for relaxation [2]. Several of our Presidents [3] are believed to have smoked it. One out of every five Americans say they have tried it. And it is still popular among artists, writers, musicians, activists, lawyers, inventors, working people, etc.

3 Q. How Long Have People Been Using Marijuana?

A. Marijuana has been used since ancient times [4]. While field hands and working people have often smoked the raw plant, aristocrats historically prefer hashish [5] made from the cured flowers of the plant. It was not seen as a problem until a calculated disinformation [sic] campaign was launched in the 1930s [6], and the first American laws against using it were passed [7].
