A heated propagator is a horticultural device to maintain a warm and damp environment for seeds and [[Cutting (plant)|cutting]]s to grow in. They generally provide bottom heat (maintained at a particular temperature) and high [[humidity]], which is essential in successful seed germination and in helping cuttings to take root. In colder climates they are sometimes used for plants like peppers and [[Sweet pea|sweet peas]] which need warmer environments (about 15°C, for the plants listed) in order to germinate. If excessive condensation forms on the inside of the lid, the gardener can open the ventilating holes to regulate the temperature a little.

Non-electric propagators (mainly a seed tray and a clear plastic lid) are a lot cheaper to purchase than a heated propagator, but without the constant regulated warmth and bottom heat provided by a heated propagator, growth of seedlings tends to be slower and less consistent (with increased risk of seeds failing to germinate).<ref>{{cite web |title=13 heated propagators for nurturing your plants in 2023 |url=https://www.gardenersworld.com/product-guides/growing/heated-propagators/ |website=BBC Gardeners World Magazine |access-date=18 October 2023}}</ref><ref>{{cite web |title=Heated propagators: tried and tested |url=https://theenglishgarden.telegraph.co.uk/buyers-guide/heated-propagators-tried-and-tested/ |website=The English Garden |access-date=18 October 2023 |date=17 January 2018}}</ref>
