JOMHYM Jinghan Optoelectronics | Seedling Heating Mat

Jinghan operates full-chain production at its self-owned industrial park. We can deliver complete sets matched with our proprietary 24-cell and 40-cell LED seedling trays, suitable for seedling cultivation of vegetables, flowers, succulents, medicinal herbs and aromatic plants, with a full range of foreign trade certifications.## I. Core Product Features1. Material & Craftsmanship – Waterproof, Fold-resistant, Durable & Reusable It adopts integrated hot-pressed edge sealing with multi-layer thickened PVC/silicone material for seamless waterproof sealing without water leakage. The surface is splash-proof to prevent electric leakage during watering. Flexible and foldable for easy storage, drop-resistant without deformation, wear-resistant and anti-aging for years of repeated use; stains can be wiped clean directly with a damp cloth. The built-in carbon fiber heating film paired with a double-layer insulation structure avoids seedling burn caused by local overheating, and resists cracking and bulging after long-term operation. 2. Constant Temperature Heating – Targeted Root Warming to Accelerate Germination Far-infrared technology delivers even heat that only warms the root zone of potting soil instead of heating ambient air. It stably maintains the optimal seedling growing soil temperature of 20–30°C, 5–11°C higher than room temperature, drastically shortening germination cycles, boosting seedling emergence rates and reducing rotten seeds and stunted seedlings. An optional external digital temperature controller allows adjustable temperature ranging from 5°C to 42°C with automatic power-off protection against overheating, delivering energy-saving intelligent constant temperature control. Its low-power energy-efficient design cuts power consumption under long-term continuous operation. 3. Size & Matching Accessories – Multiple Sizes Compatible with Full Seedling Kits Fits JOMHYM’s 24-cell and 40-cell seedling plug trays. Supports 110V US standard voltage, 230V EU standard voltage and national standard voltage, with customized plugs available for different countries, ideal for global supermarkets and cross-border e-commerce sales. Can be shipped as complete bundles together with LED grow lights, transparent seedling domes and seedling cultivation tools. 4. Safety & Certifications (Core Advantage for Foreign Trade) The product holds CE, FCC and RoHS safety certifications. Our factory manufactures under ISO9001, ISO14001, ISO45001 and BSCI management systems, complying with European and American import standards. Built-in thermal fuse protection eliminates risks of short circuits and fire hazards, enabling safe use for indoor household gardening and small greenhouses. 5. Services & Customization Our 60,000-square-meter workshop at Tangxia Jinghan Industrial Park maintains abundant spot inventory, supporting both FOB and domestic delivery terms. ODM and OEM services are available, including customized dimensions, adjusted power ratings, private labeling with customer LOGOs and bundled temperature control kits. We fully respect customers’ intellectual property rights and offer processing with supplied materials as well as customized complete set combinations.## II. Application ScenariosSowing on household balconies, cutting seedling raising in greenhouses, germination of succulents and medicinal herbs, aromatic plant seedling cultivation; multi-purpose applications also include reptile breeding and heating for small-scale fermentation.
