Place of rapid growth - with an electric blanket? (6)
I believe the answer is:
hotbed
'place' is the definition.
(I have seen 'vicious place' mean 'hotbed' so perhaps 'place' could also mean 'hotbed')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hotbed that I've seen before include "Place with ideal conditions for rapid growth" , "Scene of rapid growth, as of intrigue" , "vicious place" , "Forced to grow up early in this" , "Place with ideal conditions for development" .)
