VIVOSUN 40-Cell Seed Starter Tray with LED Lights, Heat Mat & 3.6-Inch Higher Cover

All-in-One Seed Starting System for Busy Indoor Gardens

Kick off your seedlings with a purpose-built setup from VIVOSUN. This 1-pack includes a 40-cell seed starter tray, integrated LED light bars, and a 10"x20.75" seedling heat mat, all designed to support early growth in compact spaces. The combination of light, warmth, and structured containment creates a convenient micro-environment that can help you manage seed starting with less guesswork.

Beyond visibility, the design emphasizes control. A clear dome lets you monitor progress without repeatedly lifting the lid, while twin adjustable vents let you tune humidity and airflow to suit different seeds. The sturdy handle and secure snap-fit ensure you can inspect and adjust without shaking the setup, keeping seedlings calm and undisturbed.

Smart Design for Stronger Seedlings

• 240-cell layout enables simultaneous starts while reducing crowding and root competition.
• Black-bottom tray promotes root development and helps drainage through evenly placed holes.
• 3.6-inch higher cover creates extra space for growing roots and developing stems.

Heat, Light, and Easy Transplanting

The seed tray is compatible with a heating mat that covers a practical temperature range of 0 to 120°F. A dual digital display thermostat keeps you informed and makes on-the-fly adjustments simple, turning warmth into a manageable part of your routine. The included LED light bars provide supplementary light, helping tender growth strengthen as plants reach toward the source.

• Heat mat pairing supports steady warmth across the root zone for consistent seedling establishment.
• Transplanting is straightforward—lift seedlings from the cells and move them to pots or the garden, or use rockwool cubes if you prefer.
• Real-time temperature readings from the thermostat help you optimize conditions without constant guessing.

Designed for flexibility, this system works well for indoor spring starts, overwintered seedlings, or compact propagation stations in small spaces. It centralizes care and makes it easier to monitor progress at a glance, while remaining a practical option for hobbyists and busy growers alike.
