This seed starting kit brings together essential components for successful seedling growth. It includes three 60-cell seed trays, 3-matching bases, 3-clear humidity domes, and three 10 in. x 20.75 in. heat mats, eliminating the need to source individual items. The high-quality plastic trays are designed to be sturdy, reusable, and recyclable, making them a sustainable choice for long-term use. They feature no drainage holes, which simplifies care by reducing the frequency of watering and preventing any leakage from the soil. The transparent, high-rise domes fit tightly over the trays, forming a secure seal that locks in both heat and humidity, creating a favorable environment for seedlings. Each dome has 2-adjustable circular vents to control airflow, allowing for optimal light penetration and easy monitoring of plant progress. The included heat mats are waterproof and heavy-duty, warming the soil to around 10°F -20°F above ambient air temperature. This consistent, even heat promotes healthy seed germination and supports cutting propagation, ensuring plants start strong and grow robustly.
