Definition
A 'hothouse' is a heated greenhouse, used for growing plants, especially those needing warm conditions. It's essentially a controlled environment for plant cultivation. Think of it as a plant incubator, providing ideal temperatures and humidity. Hothouses allow for growing tropical or out-of-season plants. They are often used commercially to produce flowers or vegetables. The term can also metaphorically refer to an environment that encourages rapid development. It's like a plant spa, but for growth!
