2 Seed Starter Trays with LED Grow Lights and Timer – 80 Cells

Seed starter tray with LED grow light for a strong start

This set of two seed starter trays with LED grow lights helps you germinate seeds and raise young plants in a more controlled indoor environment. It is suitable for home gardeners, beginners and anyone who wants to start seedlings before the main growing season begins.

Each tray has 40 separate cells, giving a total of 80 growing spaces. Separate cells make it easier to sow different varieties and help reduce root entanglement during early growth.

Main advantages

• 2 seed starter trays with 40 cells each,
• 80 growing cells in total,
• built-in LED grow lights in both domes,
• USB-powered system,
• timer for automatic light on/off cycles,
• transparent humidity domes to help retain moisture and warmth,
• suitable for vegetables, herbs, flowers and other seedlings,
• compact size for home, greenhouse or workshop use,
• useful in rooms with limited natural light,
• reusable when properly cleaned after use.

LED grow lights for young plants

The domes include built-in LED grow lights that provide additional light during germination and early seedling development. This is especially useful in winter, early spring or in indoor areas where natural light is limited.

The lighting helps reduce excessive stretching of seedlings towards distant light sources and supports more balanced early growth.

USB power and timer

The included cable with timer allows convenient automatic control of the lighting cycle. Once set, the lights can switch on and off automatically without daily manual operation.

The system is powered via USB. A suitable USB power adapter may not always be included, so please check the package contents and power requirements before use.

Transparent humidity dome

The transparent dome helps maintain higher humidity and a more stable temperature around the seeds. This can improve germination conditions and reduce drying of the growing medium.

After germination, the tray should be ventilated regularly. Once seedlings are large enough, the dome should be removed to provide better airflow and more growing space.

Suitable for many types of plants

This seed starter tray set is suitable for germinating and raising:

• tomatoes, peppers and eggplants,
• lettuce, cabbage and other vegetables,
• basil, parsley and other herbs,
• annual and perennial flowers,
• many other plants that benefit from protected early growth.

Dimensions

• approximate tray size: 24 × 38 cm each,
• humidity dome height: approx. 10 cm,
• number of cells: 40 per tray, 80 in total.

Package contents

• 2 × 40-cell seed starter trays,
• 2 × transparent humidity domes,
• built-in LED grow lights,
• USB cable with controller/timer,
• silicone base tray,
• seed-starting and plant-labeling tools.

How to use

1. Fill the cells with a suitable seed-starting growing medium.
2. Place the seeds into the cells at the recommended depth.
3. Moisten the growing medium carefully.
4. Place the transparent dome on top.
5. Switch on the LED lighting and set the timer.
6. Check moisture daily and ventilate when needed.
7. After germination, gradually increase ventilation and later remove the dome completely.

Extra warmth for faster germination

For seeds that benefit from warmer germination conditions, this seed starter tray can be combined with a seedling heat mat. A heat mat warms the root zone and helps maintain a more suitable substrate temperature.

Important notes

• Keep the growing medium moist but not waterlogged.
• Ventilate regularly after seedlings emerge.
• LED parts, timer and USB connectors must not come into contact with water.
• Clean and, if needed, disinfect the trays before reusing them.
• Actual germination time depends on plant variety, temperature, moisture and substrate quality.

Who is this set for?

This set is suitable for home gardeners, beginners and experienced growers who want to raise a larger number of seedlings in a limited space. It can be used in a home, basement, workshop, greenhouse or other protected indoor area.
