Frequently Asked Questions
What is the best type of greenhouse for winter growing?
For cold climates, a polycarbonate greenhouse is generally advisable. Double-walled polycarbonate panels act as a thermal barrier, trapping heat more effectively than single-pane glass or plastic sheeting. Adding a small electric greenhouse heater can help maintain a stable temperature for tropical plants in freezing zones.
Do I need a foundation for my greenhouse kit?
Yes, most permanent greenhouse kits require a level foundation to ensure structural integrity. This can be as simple as a treated wood frame, a gravel base, or a concrete slab. A solid foundation prevents the structure from shifting and allows for proper drainage.
How do I prevent my greenhouse from overheating in the summer?
Proper ventilation is key. Look for kits with roof vents or side louvers that allow hot air to escape. Using shade cloth and automatic vent openers can also help regulate internal temperatures during peak summer heat.
What size greenhouse should a beginner choose?
A 6' x 8' or 8' x 10' walk-in greenhouse is ideal for beginners. It provides enough vertical space for shelving and enough floor space for larger planters without becoming overwhelming to maintain.
Can a greenhouse protect plants from pests?
Absolutely. A fully enclosed greenhouse acts as a physical barrier against deer, rabbits, and birds. Additionally, the screened vents allow for airflow while keeping out many common garden insects, reducing the need for pesticides.
