What to grow in an indoor greenhouse
Indoor greenhouses are typically made from one of two materials; glass or plastic. Plastic greenhouses tend to be cheaper and more flimsy but can be used in sheltered outdoor locations such as balconies, patios and terraces.
Glass indoor greenhouses will be heavier, last longer and are more pleasing on the eye. Most glass structures are also small enough to fit on shelving or in the middle of a table as a decorative feature. They should be placed in a location that gets good sunlight and the best indoor greenhouses will come fitted with a removable drip tray to prevent overwatering.
What you should grow in your greenhouse does depend on how big it is. Growing herbs such as basil and coriander is a good starting point if you only have space for a miniature indoor greenhouse and they can be used in a variety of recipes.
In winter months, indoor greenhouses can be used to protect tender flowers and plants. Avoid any plants that grow too big and choose plants that will enjoy being inside. These could include tomatoes and chillies, and flowers such as African violets and begonias.
