Frequently Asked Questions (FAQs)
1. Do lean-to greenhouses need to be attached to the wall?
While many models are freestanding and designed to sit flush against a wall, attaching them adds significant stability. Most kits include wall-fixing accessories or ropes to secure the frame to your house or fence, which is highly recommended for windy areas.
2. Does a lean-to greenhouse get enough sun?
Yes, if placed on a south-facing wall (in the Northern Hemisphere). The wall acts as a thermal mass, absorbing heat during the day and releasing it at night, often keeping the greenhouse warmer than freestanding models.
3. Can I use these greenhouses indoors?
Absolutely. Many gardeners set up lean-to greenhouses in basements, garages, or sunrooms to start seeds in late winter. Just ensure you use grow lights if natural sunlight is insufficient indoors.
4. How do I secure the greenhouse against high winds?
Use the included ground stakes and guy ropes. Additionally, place heavy pots or pavers on the bottom frame bars (or use the weight bags provided with models like the Ohuhu) to anchor the structure to the ground.
5. Is the shelving removable in these greenhouses?
Yes, most wire shelves in these kits are removable. This allows you to customize the layout to accommodate taller plants like tomatoes or small fruit trees as the season progresses.
