This is a replacement for a ventilation plate of seed trays (window greenhouses).

Seed Trays and Window Greenhouses without Ventilation

Seed trays and window greenhouses without ventilation are often used for germinating seeds because they provide a stable and protected environment. Germination requires a constant temperature and high humidity, which are best achieved in a closed setting. Without ventilation, the humidity can be maintained, preventing the seeds from drying out and thus improving the germination rate. The closed environment also shields the delicate seedlings from temperature fluctuations and drafts that could negatively impact their growth. Additionally, the risk of pests and pathogens is minimized since access from the outside is limited.

Seed Trays and Window Greenhouses with Open Ventilation

On the other hand, seed trays and window greenhouses with open ventilation are primarily used for cultivating cuttings or young plants. These stages of plant development still need a protected environment, but adequate ventilation is crucial to prevent mold growth and waterlogging. Open ventilation ensures better air circulation, reducing the risk of fungal diseases and resulting in stronger, more resilient plants. Young plants and cuttings benefit from the fresh air, which strengthens their roots and leaves, promoting faster and healthier growth. Furthermore, controlled ventilation allows the plants to adapt to future outdoor conditions, enhancing their survival chances once they are transplanted.
