Greenhouses in Asturias: practical guide for year-round cultivation

Asturias is green, humid and beautiful, but its climate can be challenging if you want a productive garden year-round. Frequent rains, high ambient humidity and temperature swings make many vegetables suffer in the open air. That's why more and more people are installing greenhouses in Asturias to protect crops and extend the season.

In this guide we tell you what type of greenhouse works best in the region, how to get the most out of it in a humid climate and what crops usually give the best results.

Why a greenhouse is key in Asturias

In an oceanic climate, the greenhouse helps you control three fundamental things:

• Temperature: softens cold nights and sudden rises.
• Humidity: protects from direct rain and prevents waterlogging.
• Wind: reduces stress on tender plants and improves flowering.

The result is a more stable garden, with fewer losses and more regular harvests.

The plastic tunnel greenhouse: the most practical option

For Asturias, the plastic tunnel greenhouse is one of the best choices for three reasons: price, quick assembly and climate adaptation. Quality three-layer plastic at 800 gauges withstands rain, moderate hail and temperature changes, and galvanized steel arches provide strength on windy days.

Plus, the tunnel offers a large air volume, which helps reduce excess moisture inside if you ventilate well.

Tips to avoid excess humidity

Humidity is the big issue in Asturias. A well-ventilated greenhouse is essential:

• Open doors and windows during central hours of the day.
• If possible, incorporate side windows or an extra front.
• Avoid watering in the evening to avoid accumulating night condensation.
• Maintain adequate distance between plants to favor air circulation.

With these steps you reduce the risk of fungi and improve leaf and fruit development.

What to grow in a greenhouse in Asturias

There are so many crops that work very well under plastic. Some especially recommended:

• Tomato, pepper and eggplant: they need heat and appreciate the protection.
• Lettuce, chard and spinach: become more tender and clean.
• Strawberries and red berries: avoid excess water on fruit and improve quality.
• Aromatic plants: basil, parsley or mint last longer.

If you rotate crops and plan by seasons, you can harvest almost year-round.

Structure and materials: what really matters

Not all greenhouses are the same. In Asturias, it's worth prioritizing:

• Galvanized steel arches with reinforcement.
• Three-layer plastic at 800 gauges with UV treatment.
• Good closing system for sides and fronts.
• Firm anchoring to the ground to prevent wind problems.

A well-assembled greenhouse lasts for years and becomes your garden's best ally.
