Autumn Atrium

 Perpetual Temperate Zone Autumns
  (+8)
(+8) 		  [vote for,

The autumn atrium is an enclosed room with minimal plant life (nothing tropical), an overpowered air conditioner, fake autumn leaves, and a giant overhead fan. The room doesn't even call for direct sunlight. A timer switch to the fan picks up and a cold breeze (50-60º F, 10-16º C) vortexes the fake colored leaves around the room.

Enjoy a refreshing 5 minutes with a warm cup of tea in this perpetual autumn.

       Can I have mine with a little direct sunlight? I love bright autumn and winter days.

       I'm sure you could, or you could add cold grow lights. This was just designed as a cost effective atrium for those who may have offices in cities where direct sunlight isn't always available but still want something refreshing and different.

       This sounds more like an autumn atrium automata to me rather than a simple autumn atrium.

       Leaves turn to autumn colours through a process sometimes called hibernalism. Production of a plant hormone called gibberellin is reduced as autumnal days begin to shorten.   

       It is possible to induce hibernalism more regularly than is normal, by creating a cool climate and shorter daylight periods artificially. Serious bonsai enthusiasts muck about with it, from time to time.   

       My father has used it, to induce autumn colour in a liquidamber (sweetgum) tree in the tropics where he lives.

       Is it possible to give the trees the nutrients that the chlorplasts would otherwise provide, thus with low lighting and the right chemicals, you would keep the trees with year round colors?
—sartep, Nov 03 2004
   

       There's a bit of a problem with the normal path of transmission of the requisite chemicals, I think. The roots pick up some nutrients, and water, primarily.   

       The leaves perform the photosynthetic processes, to yield sugars and the like. Roots are never green, so they don't even contain chloroplasts that you might be able to activate.

       What I mean, is it possible to inject or feed some way, the trees those certain sugars?
