Tailored to the needs of nursery operations

The requirements of young tree growers are distinct. Our greenhouses are specifically designed to support the growth of both local forest species and rare or endangered varieties. With advanced control over temperature, humidity, and light, our solutions create ideal conditions for cultivating strong, healthy seedlings while safeguarding crops from harsh weather and pests.

This tailored approach empowers growers to enhance plant quality and ensure higher survival rates during transplantation, fostering long-term success in nursery operations.

Why choose a greenhouse for your commercial nursery?

Optimal Environmental Control

A greenhouse allows precise regulation of growth conditions—temperature, humidity, and light—to promote rapid, uniform germination and healthy plant development.

Improved Survival Rates

By providing stable and tailored growth conditions, seedlings cultivated in greenhouses develop greater resilience, ensuring higher survival rates after transplantation.

Support for Biodiversity

Greenhouse cultivation enables the production of rare or sensitive forest species, which is crucial to reforestation and biodiversity conservation.

Protection Against Weather Extremes

By shielding crops from extreme weather conditions, greenhouses ensure steady growth and protect young plants from frost, strong winds, and heavy rainfall.
