Overview

Meet the VIVOSUN seedling heat mat, a compact heating pad designed to create a warm, stable microclimate for germination, propagation, and small-scale fermentation projects. It maintains a precise temperature range around 68–86°F (20–30°C), helping trays of seedlings, cuttings, or glass jars stay within an ideal zone for steady growth. The soft, even warmth feels comforting to delicate roots and developing shoots, while the compact 3x20 inch footprint fits standard setups without crowding your workspace.

Constructed for longevity, this mat uses durable PVC and advanced far-infrared heating to deliver consistent heat without hotspots. A reinforced heating film with double insulation helps protect the root zone and pairs well with a humidity dome to maintain humidity and dew. The surface is IP67 waterproof, making it easy to wipe clean after use. Note: indoor use only and do not immerse in water.
