So in general, regarding perishable foods like meat, most dairy, unshelled eggs and shell eggs (in the US) , cooked casseroles, and so on: if the food (or its perishable components) have been at room temperature for more than two hours, you should discard that food.
This directly effects how comfortable it will feel outside. Many times, relative humidity can be misleading. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%.
The indoor plants that are happy to put down roots outside. Last updated at 22:00 15 February 2007. Gardeners are discovering their own greenhouse effect because of climate change-they can now grow indoor plants outside.Milder winters mean that many plants from warmer climates can cope outdoors for most of the year. They may even prefer to be outside because the air in modern homes can be too dry for them.here were some casualties, but nine of the plants survived outside, although some such as rubber plants still needed to be brought in during the coldest parts of a typical British winter.
