Winter Sowing
Winter sowing is a method of starting seeds outdoors in winter. This is generally done with seeds that require a period of cold stratification. The method takes advantage of natural temperatures, rather than artificially refrigerating seeds. Winter sowing involves sowing seeds in a miniature greenhouse outside during winter, allowing them to germinate in spring. Users of this method have had success in most hardiness zones. Advantages There are many advantages to winter sowing: * It is simple to do. * It's efficient. You do not have to run grow lights for weeks at a time when starting seeds indoors. * You don't need to worry about having leggy seedlings because they are planted and grown outdoors. * There is no need to harden off the seedlings as they are already acclimated to outdoor conditions. They are ready to plant whenever the outside temperature has sufficiently warmed. * Saves space indoors for plants that need to be started prior to planting outside. * It allows someone ...

Seeds
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general meaning that anteda ...

Greenhouse
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of Transparent ceramics, transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to manage growing conditions, including air temperature, relative humidity and vapour-pressure deficit, in ord ...

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Plastic Bottle
A plastic bottle is a bottle constructed from high-density or low density plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. The size ranges from very small bottles to large carboys. Consumer blow molded containers often have integral handles or are shaped to facilitate grasping. Plastic was invented in the 19th century and was originally used to replace common materials such as ivory, rubber, and shellac. Plastic bottles were first used commercially in 1947, but remained relatively expensive until the early 1950s when high-density polyethylene was introduced. They quickly became popular with both manufacturers and customers because compared to glass bottles, plastic bottles are lighter, cheaper and easier to transport. However, the biggest advantage plastic bottles have over their glass counterparts is their superior resistance to breakage, in both production and transportation. Ex ...

Disposable
A disposable (also called disposable product) is a product designed for a single use after which it is recycled or is disposed as solid waste. The term is also sometimes used for products that may last several months (e.g. disposable air filters) to distinguish from similar products that last indefinitely (e.g. washable air filters). The word "disposables" is not to be confused with the word "consumables", which is widely used in the mechanical world. For example, welders consider welding rods, tips, nozzles, gas, etc. to be "consumables", as they last only a certain amount of time before needing to be replaced. Consumables are needed for a process to take place, such as inks for printing and welding rods for welding, while disposable products are products that can be thrown away after it becomes damaged or otherwise unuseful. Etymology "Disposable" is an ''adjective'' meaning something not reusable but is disposed of after use. Many people now use the term as a noun or substant ...

Disposable Cup
A disposable cup is a type of tableware and disposable food packaging. Disposable cup types include paper cups, plastic cups and foam cups. Expanded polystyrene is used to manufacture foam cups, and polypropylene is used to manufacture plastic cups. As they are produced for single use, disposable cups and other similar disposable products constitute a major source of consumer and household waste, such as paper waste and plastic waste. It has been estimated that the average household discards around 70 disposable cups every year. 108 billion cups are consumed in the US per year, and the UK uses an estimated 2.5 billion paper cups every year. History The disposable cone-shaped paper cup was invented in 1908 by Lawrence Luellen, and in 1912 Luellen and Hugh Moore began marketing the Health Kup, another paper disposable cup. The Health Kup was designed to create a means for people to drink water from public water barrels without spreading germs, which occurred when people would ...
