Greenhouse Orchid Growing Guide
Choosing the Right Greenhouse for Orchids
When it comes to growing orchids, not just any greenhouse will do. The ideal greenhouse for orchids should have features that closely mimic the orchid’s natural environment. This means focusing on aspects like temperature, humidity, and light.
Space and Layout Considerations
-
Ensure ample space for air circulation to prevent mold and mildew.
-
Arrange shelves and hanging baskets to maximize vertical space.
-
Install benches to keep pots off the ground and improve drainage.
Most importantly, the layout should allow for easy access to all plants for watering, feeding, and inspection. This will help you maintain a healthy growing environment.
Ideal Materials and Design Features
The materials used in your greenhouse can make a big difference in the health of your orchids. Opt for materials that provide good insulation and light diffusion.
-
Use polycarbonate panels instead of glass for better light diffusion and insulation.
-
Ensure that the greenhouse has proper ventilation, including roof vents and side vents.
-
Install shade cloths to protect orchids from direct sunlight.
Besides that, automated systems for watering and humidity control can significantly ease the maintenance process.
Temperature and Humidity Control
Orchids are sensitive to temperature and humidity changes. Maintaining a stable environment is crucial for their growth.
For most orchids, daytime temperatures should range between 70-85°F (21-29°C), while nighttime temperatures should drop to 60-70°F (16-21°C). Humidity levels should be kept between 50-70%. To ensure proper conditions, consider learning how to automate your greenhouse with smart technology.
Use a hygrometer to monitor humidity levels and a thermostat to control temperature. Humidifiers and fans can help maintain the ideal conditions.
The Top 5 Orchids to Grow in a Greenhouse
Choosing the right orchids can make your greenhouse journey much more rewarding. Here are the top five orchids that thrive in greenhouse conditions: To further enhance your greenhouse experience, consider integrating smart technology for automation.
Phalaenopsis
Phalaenopsis, also known as the moth orchid, is one of the most popular orchids for beginners. They are known for their long-lasting flowers and ease of care. For optimal growth, consider using LED grow lights to ensure they receive the right amount of light.
Phalaenopsis orchids prefer indirect light and a temperature range of 65-75°F (18-24°C). They thrive in high humidity and require a well-draining potting mix.
Cymbidium
Cymbidium orchids are known for their stunning flower spikes and long-lasting blooms. They require cooler temperatures compared to other orchids, making it important to consider air movement optimization in your greenhouse setup.

Follow these steps:
-
Fill the pot one-third full with the potting mix.
-
Place the orchid in the pot, spreading the roots evenly.
-
Add more potting mix around the roots, gently pressing it down to secure the plant.
-
Ensure the base of the orchid is level with the top of the potting mix.
-
Water thoroughly after planting to settle the mix around the roots.
Proper planting helps establish a healthy root system and promotes growth. For more tips on improving your greenhouse setup, consider reading about best LED grow lights for greenhouse gardening.
When and How to Repot
Orchids should be repotted every 1-2 years or when the potting mix breaks down. Repotting helps refresh the growing medium and allows room for new root growth.
Here’s how to repot an orchid:
-
Remove the orchid from its current pot and gently shake off the old potting mix.
-
Trim any dead or damaged roots with sterilized scissors.
-
Choose a new pot that is slightly larger than the previous one.
