>chamber ?" (LOST THE EMAIL) What in the world is a growth chamber ?
A growth chamber is a more controlled environment than a greenhouse; often
the light source is entirely artificial, and the temperature, humidity and
pretty much the whole environment is dialed in and mad or woman-made. a
small growth chamber, for example, would be a terrarium with a fluorescent
light over it and a thermometer somewhere in it. At Harvard, they make
their growth chambers out of commercial meat refrigerators with banks of
fluorescent lights set about only 1/2 inch apart. the ballasts supplied
the heat, in fact, too much heat.....one can 'remote' the ballasts, and put
them someplace away from the lights themselves and blow a fan accross them
to supply heating for a cellar-sized growth chamber, which is what i did
when I lived in Boston.
