Grow More Healthy Seedlings with Consistent, Even Root Warmth Give your seeds the stable growing conditions they need with this daisy chain heat mat system. Designed to provide gentle, even bottom heat, it helps maintain the ideal root-zone temperature for faster, more reliable germination while reducing the hassle of managing multiple individual heat mats. Unlike standard propagation mats, this bundle lets you connect multiple mats together, making it easier to heat several growing trays at once using one compatible temperature controller (controller sold separately unless included with your setup). Why You'll Love It Daisy chain design connects multiple heat mats for a cleaner, more organized growing setup. Supports faster germination by maintaining recommended root-zone temperatures between 68–86°F (20–30°C). Up to 40% higher germination rates compared to unheated growing conditions. Even heat distribution promotes healthier seedlings and stronger root development. Fits standard 1020 propagation trays for seamless integration into most seed-starting systems. Built for Reliable Everyday Use Durable PVC construction designed for repeated indoor use. IP67 waterproof surface helps protect against moisture during propagation. Flame-resistant, abrasion-resistant, and dust-resistant finish for added durability. Easy-to-clean surface simply wipes clean after use. Long 5.9 ft (1.8 m) power cable provides flexible placement around your growing area. More Than Just Seed Starting While ideal for seed germination and seedling propagation, this versatile heat mat system can also be used for hydroponic growing, plant propagation, home brewing, fermentation projects, and selected reptile habitat applications that require gentle, consistent warmth.
