The Palram Hybrid Greenhouse is a greenhouse that comes in many different sizes so you should be able to pick the perfect size for the space you have available. This greenhouse has a roof vent which is great for letting fresh air in and keeping your plants happy, the panels also block out 99% of UV rays. This greenhouse kit does require assembly and is on the larger side as far as residential greenhouses go so it is not portable. Make sure you pick out the best spot possible to place it. When it is built it will provide your flowers and plants with the protection they need in a safe environment.
