Greenhouse accessories can make a big difference in how comfortably and efficiently you grow throughout the year. From managing summer heat to protecting plants during winter cold snaps, a few practical additions can help you get more from your growing space.

1. Automatic Vent Openers

Greenhouse temperatures can rise quickly, even on mild days. Automatic vent openers respond to temperature changes, opening windows as the greenhouse warms and closing them as it cools. They help improve ventilation without requiring constant manual adjustments.

2. Shade Cloth and Curtains

During warmer months, too much direct sunlight can cause greenhouse temperatures to climb and leave plants vulnerable to heat stress. Shade curtains help reduce incoming sunlight, making them especially useful during the hottest part of the growing season.

Our Victorian greenhouse shade curtains reduce incoming sunlight by approximately 60%.

3. Greenhouse Heaters and Thermostats

A greenhouse captures warmth from the sun, but that doesn’t mean it will stay warm overnight. In colder climates, supplemental heating may be necessary to protect tender plants and extend the growing season. Pairing a properly sized heater with a thermostat helps maintain a more consistent temperature while avoiding unnecessary energy use.

4. Exhaust Fans and Airflow

Roof vents alone may not provide enough airflow during prolonged hot weather. Exhaust fans help remove warm air, while intake vents allow fresh air to enter. Together, they can improve air exchange and help prevent excessive heat buildup.

5. Shelving and Plant Supports

Making good use of vertical space is especially important in smaller greenhouses. Shelving keeps seedlings and supplies organized, while plant hooks and supports provide room for climbing crops. Plan your layout around access to doors, windows, and watering equipment.

Choosing the Right Accessories

Not every greenhouse needs every accessory. Your climate, the plants you grow, and how you use your greenhouse should guide your choices. Keep in mind that accessories vary by greenhouse model, so always check compatibility before ordering.
