==Seed propagation mat==
An [[electric]] '''seed-propagation mat''' is a heated [[rubber]] mat covered by a metal cage that is used in [[gardening]]. The mats are made so that planters containing seedlings can be placed on top of the metal cage without the risk of starting a [[fire]]. Another example is a ''seedling heat mat'', multiple layers of durable, water resistant plastic material with insulated heating coils embedded inside (similar to underfloor heating systems, but with rubber mat instead of flooring).<ref>{{cite web |last1=Sheehan |first1=Lindsay |title=5 Best Seedling Heat Mats For Faster Germination |url=https://www.ruralsprout.com/seedling-heat-mats/ |website=Rural Sprout |access-date=17 October 2023 |date=6 January 2021}}</ref> In extreme cold, gardeners place a loose plastic cover over the planters/mats which creates a sort of miniature [[greenhouse]]. The constant and predictable heat allows people to raise seedlings in the winter months when the weather is generally too cold for seedlings to survive naturally outside. When combined with a [[Grow light|lighting system]], many plants can be grown indoors using these mats.<ref>{{cite web |last1=Dyer |first1=Mary H. |title=What Does A Heat Mat Do – Using A Heat Mat For Seedlings |url=https://www.gardeningknowhow.com/garden-how-to/propagation/seeds/how-to-use-a-heat-mat-for-plants.htm |website=Gardening Know How |access-date=17 October 2023 |language=en |date=5 October 2022}}</ref> This can increase the variety of plants that a gardener can use.
