Gardening - What are Annuals and Biennials?

True annuals are plants that will complete their life cycle within twelve months of sowing. Biennials require two growing seasons to do so and are usually sown in summer to flower during the following spring and summer.


Many other plants that botanists would define as perennial can be treated as annuals, although some are half-hardy and, while able to flower well for a single season, are not hardy enough to be used for more than one year. Half-hardy annuals are generally raised in a greenhouse, then ‘pricked out’ (transplanted, a few centimeters apart in larger boxes) and grown under protection before being planted out.

Cold Frame Greenhouse - Maximize The Natural Warmth Of The Sun

A cold greenhouse is not warmed by a heating device. The environment is warmer than the outside - this is due to the heat of the sun’s rays being trapped inside the covering material - be it glass or plastic - during the warm season, and heat accumulated in the soil being released back into the greenhouse during the fall.


In summer, cool air enters the greenhouse through side ventilators near the base of the wall, keeping a steady stream of fresh air flowing around the plants.

Congress Needs to Wake Up to Nuclear Waste Disposal, Part 2

Inside Alloy 22 Engineered Barrier Canisters


Within the first 1,000 years, about 99 percent of the radioactivity in the reactor fuel will have dissipated through the natural process of radioactive decay. For those who believe the nuclear waste will be dumped in some hole in the ground as some fanatical environmentalists falsely compared this to a landfill disposal think again. The Department of Energy designed rust-resistant canisters lined with titanium drip shield to prevent water entry. A new alloy for these canisters was created in 1987 called Alloy 22, which is a blend of nickel, chromium and other corrosive-resistant metals.

Your Personal Kyoto Protocol - Our Individual Responsibility To Reduce Greenhouse Gases

It is now time for each and every one of us to make a positive effort to help reduce the impact of Global Warming on our good earth. The official cause for global warming has been unequivocally determined at the 2007 IPCC (Intergovernmental Panel on Climate Change) meeting in Paris France. Established in 1988 by the the United Nations, the IPCC has just completed its 4th Assessment Report, which has established that global warming has been human-caused and for the most part greenhouse gases have been the largest contributor to the acceleration of global warming. Effects of global warming will definitely be experienced in this century.
