My seeds have germinated in a few days so it’s done its job. Easy to use and not too big for the windowsill ### ⭐⭐⭐⭐⭐ Good buy *by K***A on 25 June 2026* Does what says in tin. Very good ### ⭐⭐⭐⭐ Helped seeds germinate rapid *by M***K on 15 August 2024* Made a huge difference in germination time for chillies and tomatoes. I have used it for other seeds as well and it has performed as expected. Will have to see if it stands the test of time as it is only used when needed at the start of the year. The heat is a little uneven with colder parts but I moved the seeds around. Great price and worth getting if you germinate your own seeds . ## Frequently Bought Together - Hyindoor Seedling Heat Mat Heated Propagator Durable Waterproof Seedling Heating Pad for Winter Hydroponic Indoor Seedling Germination 10"x 20.75"(25 * 52cm) - LUOCAI Grow Lights for Indoor Plants 80 LEDs 4 Arm Full Spectrum LED Grow Light with Timer, 6500K/3000K/660nm Grow Lamp for Seedlings and Succulents with Remote Controls, 10 Dimming Level - wolezek Grow Lights for Indoor Plants, Full Spectrum LED Plant Light, 6000K/3000K/660nm 2-Head Growing Lamp with Clip, Auto ON & Off Timer 6/12/16H, 3 Modes, 5-Level Dimmable, Use for Indoor Growth --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/83760826-hyindoor-seedling-heat-mat-heated-propagator-durable-waterproof-seedling-heating](https://www.desertcart.jp/products/83760826-hyindoor-seedling-heat-mat-heated-propagator-durable-waterproof-seedling-heating) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-18*
