Overview

The Riga XL greenhouse is built to endure challenging climates with confidence. Its reinforced aluminum frame and curved side walls provide superior resistance to snow, wind, and hail. The thick 16 mm polycarbonate glazing delivers outstanding insulation and light diffusion, maintaining an interior environment that supports healthy plant growth. The polycarbonate fits tightly inside the engineered framing. Every detail reflects Hoklatherm’s commitment to quality and precision.

As the largest model in the Riga series, the XL offers taller and wider interior space for plants and projects alike. It creates a warm, protective environment that helps gardeners extend the growing season and achieve consistent results, even in harsh conditions. The Hoklatherm Riga XL combines capacity, craftsmanship, and performance in a structure designed to last for generations.
