My Tiberian Growdome System Review

Highly Recommended

I've really worked on the chapters in this ebook and can only say that if you put in the time you will never revert back to your old methods.

In addition to being effective and its great ease of use, this eBook makes worth every penny of its price.

The Introduction of Indica

However, the negative characteristics of reduced potency (lower THC content) slow, flat, sedative, dreary effect (high CBD content) skunky, acrid aroma and harsh taste quickly became associated with many indica x sativa hybrids. To consumers, who often prefer sativas, indica has not proven itself to be as popular as it is with growers. Also, the dense, tightly packed floral clusters of indica tend to hold moisture and to develop gray mold (Botrytis), for which the plants have little natural resistance. Mold causes significant losses, especially in outdoor and glasshouse crops, and was rarely a problem when only pure C. sativa varieties were grown. In addition, fungal contamination of medical Cannabis could prove a serious threat to pulmonary or immunocompromised patients. Although consumers and commercial cultivators of the late 1970s initially accepted indica enthusiastically, serious breeders of the late 1980s began to view indica with more skepticism. Although indica may currently...

Step 2 Gathering Preparing Raw Materials

Poisons and raw materials for poison are rarely sold in stores, so an assassin who wants to be assured of pure ingredients must often go looking for them at the source. This can be as simple as a walk to the local greenhouse or a difficult break-ing-and- entering. It takes about 10 minutes per DC point of the poison to find a large enough amount of common poisonous materials to use, be it animal, vegetable, or mineral.

Planting and Maintenance

One grower I know keeps a stream of plants moving from indoors to his outdoor gardens. He plants the first crop of clones in three-gallon (l 1 L) pots in a greenhouse, hardens them off, and moves them to their final location, The second crop is moved into the greenhouse when the first crop is moved out. He repeats this process three to four times during the season.

Recent Observations On Environmental Effects

That environmental variables which stressed the plants resulted in increased cannabinoid content. By far the most carefully controlled study was done in 1975 on Afghani plants grown in a greenhouse. All the variables were kept constant except the soil 11 distinct types native to Maryland were used. At six weeks, before the plants flowered, they were harvested and their canna-binoids measured. THC exceeded CBD for all soils except one which was somewhat higher than average in potassium and lower in calcium. Since this one exception had a low total cannabinoid content, the conclusion was that deficient soil retarded development and conversion of CBD to THC. In the study, the CBD content did not vary significantly but THC varied by a factor of seven, exceeding CBD from slightly more than one to about six times. The two soils which produced plants with twice as much THC content as the other nine soils, had low magnesium, low iron and a lightly acid pH, and these plants tended to be short,...

Misdiagnosed Disorders

Heat Stressed Cannabis Plants

Once a plant shows symptoms, it has already undergone severe nutritional stress. It will take time for the plant to resume vigorous growth. Correct identification of each symptom as soon as it occurs is essential to help plants retain vigor. Indoor, greenhouse, and some outdoor marijuana crops are harvested so fast that plants do not have time to recover from nutrient imbalances. One small imbalance could cost a week of growth. That could be more than 10 percent of the plant's life

Next Generation Seeds

Our next stop was courtesy of Hext Generation Seeds. We toured a small greenhouse of injured plants and two indoor growrooms. The plants in the greenhouse had recently been transplanted and were on the mend. Framed by two-by-fours and covered with an inexpensive plastic skin, this greenhouse was located in a low-lying grassy field. This well-chosen site ensured that the plants received full sun. A natural breeze provided near-perfect ventilation through an open wall and a vent hole on the opposite end.

Psilocybe Cyanescens Potent Mushrooms Growing On Wood Debris

In 1976, bluing mushrooms growing on plant debris were found in the Saarland region of Germany. Other collections came from the Southern regions of the Black Forest (MTB 7515, 1959, 1963), as well as the Vogtland area (1979) and the Rheinland area (MTB 4706, 1982). Similar mushrooms were also discovered near Hamburg (MTB 2428, 1983) and Bremen (1982, 1983). The latter collections are especially interesting, because the greenhouses at the Rhododendron Park and People's Park in those cities provided layers of wood chips during the fall which enabled the mushrooms to fruit much more prolifically (thousands of mushrooms) than they did naturally in surrounding areas, where the species was also fruiting in several locations. These findings most likely indicate the presence of a similar, imported species, because native fruiting bodies require exposure to the shock of colder temperatures of fall in order to develop

Pharmaceutical interest A large number of Geraniaceae are ornamental. The so-called bedding and greenhouse Geranium is in fact a Pelargonium. In regard to pharmaceutical interest, the volatile oil obtained by distillation of the aerial part of various Pelargonium species, including Pelargonium grave-olens., has been used in Western countries to make perfumed cosmetics (Geranium Oil, British Pharmaceutical Codex, 1959). The very distinctive fragrance of geranium oil is attributed to a subtile mixture of terpenes, including geraniol, linalool, citronellal and limonene, which cause contact dermatitis in sensitive individuals. To date, the pharmacological potentials of Geraniaceae are virtually unexplored and one might say that antiviral and cytotoxic principles are yet awaiting discovery.

Polyvinyl chloride (PVC) is two to five times more expensive than PE but can last five years or longer. Polyvinylchloride is pliable, transparent or translucent, and comes in four to six foot (1.2-1.8 m) widths which can be sealed together to provide a super-wide piece. Ultraviolet inhibited corrugated plastic panels provide another option. The panels can be used in cold frames, propagation houses, and greenhouses to provide excellent wind and snow protection and optimal solar heat collection. UV inhibited corrugated plastic also has insulating properties (2.5 R insulation 3.5 mm panels, 3.0 R 5.0 mm panels). This backyard greenhouse near Paris, France was recently planted.

This fluctuation in heat is difficult and expensive to control. Hot and cold dips also affect the ratio of nutrient to water plants need and use, which makes growing in a greenhouse more demanding than growing indoors.

The city of Arcata, which sports four marijuana dispensaries, was the site of a house fire in which a fan had fallen over and ignited a fire it had been turned into a grow houseboy its tenant. Per Arcata Police Chief Randy Mendoza, altered and makeshift no code electrical service connections and overloaded wires used to operate high-powered grow lights and fans are common causes of the fires. Large indoor marijuana growing operations can create such excessive draws of electricity that PG& E power pole transformers are commonly blown. An average 1,500-square-foot tract house used for growing marijuana can generate monthly electrical bills from 1,000to 3,000 per month. From an environmental standpoint, the carbon footprint from greenhouse gas emissions created by large indoor marijuana grow operations should be a major concern for every community in terms of...

The flood system consists of a tub or container holding a medium that is completely flooded on a regular basis, usually once, twice, or three times daily, depending on the growth stage and environmental factors. The medium holds enough moisture between irrigations to meet the needs of the plant. First-generation commercial greenhouses using this method were usually built with long beds of gravel that were systematically flooded. Today, the flood

Field Crop Production

Thc Cbd 1970s

Of North American illicit marijuana cultivators began to grow sinsemilla (Spanish for without seed) marijuana that within a few years became the predominant style of North American and European marijuana production. The sinsemilla effect is achieved by eliminating male plants from the fields, leaving only the unfertilized and therefore seedless female plants to mature for later flower and or resin harvest.* In lieu of setting seed in the earliest flowers, the female plants continue to produce additional flowers covered by resin glands, which increases the percentage of psychoactive and medically valuable A9-tetrahydrocannabinol (THC) or other cannabinoids in these flowers. Yields of terpenoid-rich essential oils produced in the resin glands along with the closely related terpenophenolic cannabinoids are also significantly raised in seedless flowers (7). Throughout the 1980s, the vast majority of domestically produced North American and European drug Cannabis was grown from seed in...

Although this substance is a pharmaceutical product, it also occurs naturally. For instance, eating lettuce generates enough nitrous oxide that scientists can measure it in a person's breath. Large quantities are produced by wild prairie grass. Humans do not receive enough nitrous oxide from such natural sources to be affected, however. The substance is also produced by the human body. One study found the amount to increase as oral hygiene declined. As with the amounts produced by grass and lettuce, the level created by the body is too small to have any known effect on a person. From a global environmental perspective, however, nitrous oxide is a gas that promotes the greenhouse effect and ozone layer destruction, and concern exists about medical usage affecting the world's climate. Medical sources are estimated to create 2 of the atmosphere's supply. Such usage may seem insignificant in that regard, but the gas is so durable in the atmosphere that any artificial source has been...

Ways To Germinate Your Seeds

This is a method whereby the seeds are placed in small unit, called a seed or clone propagator, which is designed to help plants germinate. One such kit is called a rockwool SBS Propagation Tray. Some of these kits can be heated and look like a miniature greenhouse. At the bottom of the tray is a small area where water, or even better 'some germination hormone' is poured. Small grow cubes called rockwool cubes are placed into slots in the tray, which automatically dips the rockwool into the solution (Figure 3.8). The seeds are placed into tiny holes in the cubes and the cover is then put back on the unit.

I should add here that making cross fertilized hybrids yourself can also lead to disappointment. It has happened to me too you think that finally you have created some sort of super variety for outdoor growing and then she goes and needs ten weeks in bloom. A small calculation will quickly show that if the plants only come into bloom in early September then at the very earliest it is going to be mid-November before they're ready to harvest. If you are not in a position to use a warmed greenhouse then we can best forget all about raising such a long-blooming variety.

Greenhouses, cold frames, and hot frames are all useful in extending the growing season and or protecting new plants and seedlings. Which type of structure you select depends on the size and location of your growing area, how much money you have to spend, how much time you have to grow, and security issues. Simple cold frames and hot frames can be assembled from common materials like old framed window panes and hay bales. Greenhouses are generally larger and more complex. They can be expensive to build and maintain but offer more flexibility for growing time and building use.

Light Movers

Flat white paint diffracts the light so that it is distributed more evenly through the garden. Off-whites absorb a considerable amount of light so they are avoided. The best paint for indoor gardens is greenhouse white which is formulated for maximum reflectivity.

Methods of Culture

In the section around Norfolk and Portsmouth, Va., and in other sections having a mid winter climate large quantities of parsley are grown in sash-covered cold frames during the late fall, the winter, and early spring. These frames are later used for growing beets and cucumbers. In New Jersey and in southern New England, winter and early spring parsley is grown to some extent in cold frames, in pipe-heated beds, and in sash greenhouses. High class or expensive greenhouses are not required for growing parsley, and a temperature of 45 to 60 F. is all that is required.

The Planting Medium

BARK - is lightweight, absorbs water and holds air in its pores. As it comes in contact with fertilized water it slowly deteriorates, becoming more of a compost. It is used extensively by commercial greenhouse growers. It can be substituted for lava and it weighs much less. ROCKWOOL - is the most popular substrate. Originally it was used as an insulating material in home construction. Then commercial greenhouse growers in Europe started to use it for their crops. Rockwool looks a lot like fibreglass. It is made by heating rock and extruding it into thin threads. Rockwool comes in pre-pressed blocks and filled bags. It is lightweight and it holds a tremendous amount of water, more than soil, but allows plenty of air in. It comes in several forms, blocks and cubes of various sizes, bags filled with loose fibre and bales of fibre to be placed in containers. It is reusable for several crops.

Let us assume that the states ofVermont and Florida are self-sufficient. Both produce, among other things, maple syrup and oranges. Because of the differing climatic conditions, maple syrup is scarce and expensive in Florida, and oranges are scarce and expensive in Vermont. Vermont oranges have to be grown in greenhouses, and Florida maple syrup comes from maple trees grown in large refrigerators.


In the past, distribution of cannabis seeds were limited to the local geographic region of the breeders and growers. Over the years, seed banks have become more advanced with worldwide distribution of a larger variety of cannabis seeds than ever before. The supply of seed stock originates from single individual breeders to large breeding greenhouses throughout the world. A seed bank is an institution, which stores and supplies consumers with diverse varieties of cannabis seeds, both domestically and abroad.

Playing Roles

I meet Ron and Russel at Ron's house, which is next to the train overpass in South New Brunswick. It's the kind of day where everyone blames the sweltering heat on the greenhouse effect - too many weather records are being broken for too many days straight. The gamers sit on the front steps of Ron's house with their shirts off, except for the two girls. The group defies the stereotypically nerdy image of role players -this is an attractive bunch they don't need gaming just to have a group of friends. Ron smiles and shakes my hand. His build is slight but well defined, which I imagine is due to hours of aikido practice. His hard-edged, pointy face and almost sinister voice counterbalance his quirky friendliness. He laughs at the cookies and wine I've brought as an offering of sorts, recognizing the gesture as one of unnecessary respect. He hands off the gifts to one of the other gamers, and as several begin to devour the food (these are not wealthy kids), Ron takes me upstairs to his...

W Book Review

This book also covers in depth information regarding strains and breeding. This continues to include the marijuana culture of Amsterdam and the strains that sprout up amongst the coffee shops such as GreenHouse seeds strains. There is even a picture of the King of Cannabis himself, Arujan Roskam. It covers the who's who of this segment of society from the Big Fish such as Cheech and Chong (of course ) and Willie Nelson to Jack Nicholson's Stoniest Movies. There are bits and bobs on the music industry that reflect marijuana including the references in the Beatle's songs going way beyond Lucy in the Sky with Diamonds (LSD).

How Clones Are Made

The cuttings growers make are placed in an area of high humidity to limit water stress. Growers often construct a mini-greenhouse using plastic wrap placed over the rooting chamber. Some trays come with clear plastic covers to retain moisture. The cover is removed when the plants develop roots. A fine mist spray helps relieve water stress. The clones respond best to a moderate rather than a bright light. Some gardeners light the clone garden using 2 tubes for an area 4 x 2 feet, 10 watts per square foot. Clones being rooted in water do best when the water is changed frequently and aerated using a small pump and an aquarium bubbler. Rooting blocks or medium must be kept well saturated.


Subsequent Inbreeding

Backcross Breeding - A type of breeding that involves repeated crossing of progeny with one of the original parental genotypes cannabis breeders most often cross progeny to the mother plant, This parent is known as the recurrent parent. The non-recurrent parent is called the donor parent. More widely, any time a generation is crossed to a previous generation, it is a form of backcross breeding. Backcross breeding has become one of the staple methods clandestine cannabis breeders use, mainly because it is a simple, rapid method when using greenhouses or growrooms, and requires only small populations. The principal goal of backcross breeding is to create a population of individuals derived mainly from the genetics of one single parent (the recurrent parent).

Purple Haze

Ideas Grow Sales Medication

As it got cold into winter the little white hairs started to show at the joints. The plants were put into the greenhouse and one of the plants started to smell of a fruity flavour. The sticky THC then was found around the little hairs. The big leaf then went darker with a purple edge. The outdoor temp got cold that year so a glasshouse paraffin heater was lit at night to keep them warm. Due to security, the plants were hidden from the neighbours behind a large sheet of bubble-wrap. This helped insulate the glasshouse and hide them. The plants were harvested early. Chopped at the base. Each plant was about 5 foot tall. As the hairs dried out they were ready to smoke. Stoned everyday for weeks on the crop. Environment outdoor glasshouse

Age Variations

After germination, the two seed leaves (cotyledons) appear. They also contain no cannabinoids or such small quantities that they are difficult to measure. However, within a day after the sprouting of the cotyledons the first pair of true leaves appears. These have measurable quantities of cannabinoids. A study of seeds from Thailand grown in a greenhouse found that the true leaves contained about three times as much CBD as THC and that the concentration did not change during the first three weeks of growth. The cannabinoids were being synthesized as fast as the other constituents. Another study found that Turkish plants increased their CBD content from 0.07 to 0.34 in one week and that Mexican plants increased their CBD content from 0.03 to 0.2 in three weeks. Although there were only traces of THC in the Turkish seedlings (as in the adults), Mexican seedlings rose from a mere 0.04 of THC to a respectable 0.46 at three weeks. Furthermore, at two weeks the...

Climate Control

Moving Cannabis Plant Stress

Even the best greenhouses will lose heat through radiation, conduction, convection through glass, walls, and floor (or soil), and also through vents, doors, and cracks. To counteract external variables, the internal structure of the greenhouse is, in some ways, more complex than the selection of framing and covering materials. All greenhouses need ventilation and most need fans. Look for an extraction fan with the capacity to change the air once every minute. Capacity refers to the amount of power needed to circulate the air volume of your structure. Calculate the volume by multiplying the square footage of your greenhouse by the height. Multiply the volume by sixty air changes per hour to get the cubic feet per minute (cfrri) capacity of the greenhouse.

Rogue Pollen

Cannabis Plant Trays

Rogue pollen from commercial hemp farms and wild or cultivated males can threaten sin-semilla cannabis grown outdoors or in greenhouses. Undesired pollen can drift from a few feet to hundreds of miles to pollinate flowering females and cause them to grow seeds. You may be able to grow indoors until the industrial hemp is done flowering and males are no longer releasing pollen, or plant out of the wind pattern. If pollen is severe, keep plants in a greenhouse. Cover the intake opening with a moist towel-humidity makes pollen unviable. Put one edge of the towel in a bucket of water to wick moisture. Wetting down the exterior of the greenhouse wilt also help incapacitate any wild pollen.

Removing large fan leaves to allow more intense light to reach small buds or to stress plants is crazy Large leaves are necessary to keep plants healthy. Indoors and in greenhouses where the hours of darkness are controlled, cannabis flowers for six to ten weeks or longer. This is a very short time. Hacking off branch tips to initiate more budding sites diffuses floral hormones and retards growth. Remove only leaves that are 50 percent or more damaged by diseases, pests, and cultural practices.

Another big group of cultivar is that of theWhite family.With pedigree in the strain White Widow (aka WW) this family was once one of the most competitive in seed competition. Rumoured to be a cross between 'Brazilian' and 'Indian', WW comes from the breed stables of one of the industries' most prolific breeders, Shantibaba. Originally released in Holland during the early 1990's, for many years WW flew the White family flag and set the standard of things to come. Many of the 'White' family members are still housed at the Greenhouse seed coffeeshops Amsterdam. The strains 'El Nino' (aka 'Godzilla), 'Great White Shark' (aka 'Peacemaker'), and White Rhino' (aka 'Medicinal Man'), each contain White Widow in varying parts. Since the White family is so popular it has grown in recent years to include 'SnowWhite', White Pearl', White Rose', White Russian'.and so on.


Greenhouse gardeners are used to harvesting summer crops one or two months earlier than their neighbors. Later in the season, the greenhouse environment allows them to harvest one or two months after other gardens have closed for the winter. With just a small investment of time and energy, any greenhouse can be used to grow summer as well as winter crops nearly all year round, or until freezing temperatures kill summer plants. In temperate zones the amount of light reaching sea level can vary considerably. In midsummer at noon on a clear day, I 've recorded over 10,000 lumens at the 40th parallel. (A lumen is a measure equal to one footcandle per square foot.) In midwinter at noon, the same area received only 950 lumens. Fruiting plants require 2,000 to 3,000 lumens to produce, and 1,000 to 2,500 lumens to maintain life processes and slow growth. Non-fruiting plants, such as greens and root crops, generally require from 1,000 to 2,500 lumens. Many greenhouses are already insulated and...

Backyard Growing

Backyard growers have it easy Their main worries are local kids and nosy neighbors. Growing In a backyard is relatively discreet. One method is to grow in a low greenhouse next to your house. The greenhouse can be made from translucent corrugated fiberglass. Make it 3 to 4 feet high. 4 feet long and 2 feet wide. You can easily grow a couple of plants in it. Grow small plants on Ihe patio and move Ihem indoors al night Or move them around the backyard. You can also dig a hole among regular garden plants and bury the small pot plant with the container underground. This way the container doesn't call attention to Ihe plant. James spent H years as an engineer for Grodan, a Danish soil company Most of those years, he visited greenhouses in the NetherLands, solving problems. They stiLl call htm WiLly Worlel, Dutch for problem solver. James evaluated the data he'd amassed over the years spent troubleshooting in the greenhouse industry and found that plants need bright Light, bul react slowly...


Our laziness has meant that products we can easily make in our kitchens, or grow in our back gardens, or greenhouses, are being flown around the world. What would our ancestors think of fruit from a tree not being eaten by local people, but packaged and flown 10,000 kilometres to another country, where it is driven around, stored in a cool storage facility, driven some more, spending time under lights, and finally driven some more, stored in a cool storage facility some more (your refrigerator), and then maybe eaten, or discarded. Do you think they would be proud of our progress

Group will likely be one of many to be posted on the market as this industry faces current changes. Recently medical patients in the Country of Cannabis were shocked to learn that their insurance would no longer cover their precious herbal alternative. As the first country to legalise cannabis for distribution in pharmacies, the Netherlands has been offering higher-priced and more strictly controlled cannabis to its ailing. No doubt the industry will expand or at least evolve as a result, not to mention offering a business plan of sorts for other countries attempting to legitimise medi-weed. After all, there is plenty of money to be made from those greenhouses


Organic and hydroponic growers both face the problem of replacing or cleaning the medium after each crop. Usually potting mixes and rockwool are replaced, while clay pebbles are washed. These measures are taken to prevent the cross-generational spread of disease. Some new products have been scaled down to give gardeners the same tools that were once only available only to large greenhouse growers. Several new chemicals used for greenhouse and grow room sterilization, pose less of an environmental or toxicity threat than pesticides or chlorine. The Electric Soil Sterilizer holds a cubic foot (about 7.5 gallons) of soil or other planting medium. The unit works using heat controlled by a thermostat with a range of 100-200 degrees Fahrenheit. At 160 degrees Fahrenheit the material is pasteurized, which kills most harmful organisms, but not beneficials. Sterilization, which kills most organisms and weeds, occurs at 180 degrees. It takes about 30 minutes for sterilization to occur once...

Hypertextual Forays

Both Sterling and Gibson experienced the 'cyberian vision', but their conclusions are dark and hopeless. Rather than trashing the old death-based paradigm, they simply incorporate chaos, computers, and randomness into a fairly mechanistic model. Sterling believes in systems math, cultural viruses, and the promise of the net, but, like Bruce Eisner, he doesn't see technology as inherently liberating. I worry about quotidian things like the greenhouse effect and topsoil depletion and desertification and exploding populations and species extinction. It's like it's not gonna matter if you've got five thousand meg on your desktop if outside your door its like a hundred twelve degrees Fahrenheit for three weeks in a row.

Raised beds

Is on top of a two- to three-foot (60-90 cm) high compost heap. By the time the roots penetrate into the compost, it has cooled enough that the roots are safe from burning. He places a portable greenhouse over the plants. The compost keeps plants warm while the structure protects foliage. This works exceptionally well to coax a spring harvest
