FAQ
What size greenhouse should I buy for my balcony?
Consider the available space and the plants you intend to grow. Smaller cold frames are suitable for herbs and seedlings, while larger greenhouses can accommodate a wider variety of plants - typically 6ft x 4ft or smaller is recommended for most balconies.
Are these greenhouses easy to assemble?
Most models feature straightforward assembly with included instructions and tools. However, some may require assistance depending on the size and complexity; always check the product specifications before purchasing.
What materials are these greenhouses made from?
Typically, you'll find greenhouses constructed using polycarbonate panels for light transmission and aluminium frames for strength and stability. Some models might incorporate PVC or wooden components for added durability.
How much sunlight do I need to provide?
Greenhouses require a minimum of 6 hours of direct sunlight per day for optimal plant growth. Southern-facing balconies generally receive the most light, but consider shading during the hottest parts of the summer months.
Can I use these greenhouses on windy balconies?
While designed to be weather resistant, strong winds can still pose a risk. Secure your greenhouse with tie-down straps or weights to prevent movement and potential damage, especially in exposed areas.
What kind of plants can I grow in a balcony greenhouse?
You can successfully cultivate a wide range of plants, including herbs (basil, mint, thyme), salad greens (lettuce, spinach), strawberries, peppers, tomatoes (dwarf varieties), and various bedding plants.
Do I need to ventilate the greenhouse?
Ventilation is crucial for maintaining a stable temperature and humidity level. Most models feature vents that can be opened or closed to regulate airflow and prevent overheating during sunny days.
How do I clean the polycarbonate panels?
Clean the polycarbonate panels with mild soapy water, using a soft cloth. Avoid harsh chemicals or abrasive cleaners which could scratch the surface and reduce light transmission.
What is the lifespan of these greenhouses?
With proper care and maintenance, these greenhouses can last for several years. Regular cleaning and protection from extreme weather will help to prolong their lifespan; refer to the manufacturer’s warranty for specific details.
Can I move a greenhouse that's already assembled?
While designed to be portable, larger models may become cumbersome to move once fully assembled. Consider purchasing a lighter-weight model if frequent relocation is anticipated.
