Choosing a greenhouse plan

What to compare between plans:
- Glazing: glass, twin-wall polycarbonate or film, and how each is fixed
- Ventilation: roof vents or side vents, and how many
- Base and anchoring, since a light structure must not lift in strong wind
- Orientation and how much sun the site gets
