A sunroom, on the other hand, is usually a built-in room inside a house, often connected to a living space. It’s designed more for comfort and space than for growing plants, though it can get plenty of sunlight. If you want to use it for gardening, you’d need to add grow lights or extra insulation to keep plants thriving. Sunrooms are great for casual indoor spaces, while greenhouses are better for serious plant care with more control over conditions.
