I have my one in the propergater with no problem. Put some newspapers down first .try making your own out of a storage box. The mat fits spot on. But you will need to drill some holes in it. Best of luck will. **Q: Some one in the reviews said on the instructions you can't use this product with grow lights. Is that so?** A: I have a grow light over mine my plants doing ok **Q: Will this heat my plant terrarium to 24-25°C?** A: It may do but there is no way to control it. The mat heats up to a specified temperature, but it has no thermostat and may or may not be able to maintain that temperature when it colder or warmer outside. **Q: What temperature should seeds germinate at?** A: I think it varies depending on seed types but mostly seeds like a gentle warmth which generally, will encourage germination. Germination will naturally take place as spring makes everything warmer but the seedling mat makes it easier to get all your seeds to germinate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by J***O on 11 June 2026* This little heat mat has worked a treat I did doubt it would be very effective as it came as a rolled up plastic mat It was a bit hard to get it to lay flat at first, but once you’ve got your plants or trays on it it soon lays flat Just bare with it until it does Great results with seeds and my Dahlias they came on really quick ### ⭐⭐⭐⭐⭐ Good size *by B***T on 9 February 2026* Great mats and a good size.
