The growing temperature will be determined by the comfort of the humans living in the house. Fortunately most house plants and people are comfortable at the same temperatures. However, houses are not at a uniform temperature throughout.
Some rooms are cooler or warmer.
Even within a room, some areas are cooler or warmer than the rest of the room. Temperature affects plants in several ways. Some plants require a drop in night temperature to bloom. If a plant is given all the factors needed for maximum growth, but the temperature is too cool, the plant will grow more slowly than it could. Most plants will not adapt to rapid temperature fluctuations as can occur near a doorway in the winter.
