Launch healthy seedlings with confidence

Meet the UWIOFF Seed Starter Tray set, a versatile mini greenhouse designed to support early stage growth. Each kit provides 12 seed trays, 12 watertight bases, and 12 transparent domes to create a controlled environment for seeds and cuttings.

Humidity control at your fingertips

Four adjustable vents on each dome let you tailor airflow and humidity. By tweaking ventilation, you can influence the microclimate around your young plants, helping them acclimate to germination and early root development.

• Adjust vents to increase or decrease humidity as needed
• Transparent dome enables quick visual checks without disturbing plants

Observe roots, nurture growth

The clear seed trays make it easy to monitor root formation and overall vigor. Drainage holes at the bottom of each cell prevent excess moisture buildup, helping to avoid overwatering and providing space for healthy root systems to develop.

• Watch root growth without lifting trays
• Drainage reduces standing water and potential rot

Durable, reusable, and versatile

Made from high quality plastic, these trays are built for repeated use and can be paired with heat mats to accelerate germination. Their sturdy construction supports a wide range of plants from flowers to vegetables and fruits.

Perfect sizing for beginners and seasoned gardeners

Each cell measures 1.5 by 1.5 inches and is 2.25 inches deep, with the dome standing approximately 2.3 inches tall. This compact footprint is ideal for orderly seed starting, clone propagation, or mini greenhouse setups.
