To Andrew:

                  Black is the best heat trapping color. Inside a greenhouse in a cool/cold climate this will mean a lot of heat retained that would speed up growth.

                  Likewise white pots are a lot cooler than black, green, etc. ones, particularly the side that does not receive direct sunshine. I use both black and white containers depemding on the temperature needs of the plants. Of course this is more evident as pots increase in size.
