Most beautiful orchids: Cymbidium

The first cymbidium was described in 1799 by Olof Swartz. It is cultivated in Europe since the Victorian era but in China it has been cultivated for thousands of years because of its beauty. The species form hybrids easily among themselves, so many hybrids were developed in a great variety of colors and sizes. It's an easy houseplant that may spend the summer outside. The genus Cymbidium is part of the family Orchidaceae, sub-family Epidendroideae, tribe Cymbidieae, sub-tribe Cyrtopodiinae, alliance Cymbidium. Description: Cymbidium is sympodial and forms long narrow leaves of about 60 cm high. Most species are epiphytic, rarely terrestrial.

The flower stalk grows from the youngest pseudobulb, is 90 cm tall and bears clusters of brightly colored flowers. Each flower is 5-10 cm high. Origin: Tropical and subtropical Asia, from the Himalayas to the mountains in China and northern Australia. ARBUSTO AMEAÇADO DE EXTINÇÃO É PESQUISADO NO PARANÁ.

Growing Industrial Hemp in Ontario

For centuries, its fibres have been used to make ropes, sails and clothing. The species was banned in North America in the 1930s because its leaves and flowers contain a hallucinogenic drug known as delta-9 tetrahydrocannabinol (THC). It was banned internationally in 1961 under the United Nations' Single Convention on Narcotic Drugs. In 1998, Canada created Industrial Hemp Regulations under the Controlled Drugs and Substances Act. Under the Regulations, industrial hemp seeds must be of a variety listed in Health Canada's List of Approved Cultivars. Farmer's Pal Forums - Why Eat Grass-fed Meat? Mexican group tackles pollution with vertical gardens.

When people think of Mexico City, they think of many different things — traffic congestion, for example, or colonial churches, or snow-covered volcanoes . . . or traffic congestion.

They do not think of the pristine quality of the air. There’s a reason for that. Although far cleaner than it used to be, the atmosphere that sustains the city’s roughly 20 million residents remains severely laden with contaminants. But that doesn’t mean a city can’t dream, and the massive urban conglomeration that serves as Mexico’s capital is dreaming these days — en verde. “We wanted to make something that would cause people to turn around, something that would not be overlooked, and in this way to create consciousness,” explains Mexican architect Fernando Ortiz Monasterio, the designer of seven living, breathing sculptures that have recently sprouted at some of the capital’s busier intersections.

In other words: vertical gardens. But the city suffers from a chronic shortage of public gardens. Seed Saving Handbook: Learn How to Save Seeds From Common Garden Vegetables—Free!

This is not a special or magical thing unique to aquaponics, filters in home aquariums as an example use the same families of bacteria to perform the necessary task of removing the ammonia in a very similar fashion. The Nitrogen Cycle When our fish excrete waste (we'll call it poo or poop from now on because we're all friends here) the fish poo contains a very high percentage of ammonia. Ammonia in concentrations higher than five parts per million in your tank water is harmfull to fish and in concentrations not much higher than that very toxic and would result in a rapid painfull death.

This is not to say that five parts per million is acceptable either, long term exposure would result in your fish dying slowly and painfully instead and they would be more susceptable to disease and illness as well.
