Grow herbs indoors
If you’ve got a north-facing window, you can grow herbs indoors. If the ledge isn’t wide enough to hold pots, build a hanging herb garden that can easily be disassembled when you move.
Start with easy-to-grow herbs like basil, coriander and mint. You can sometimes find small starter plants year-round in the produce department of your local supermarket.
Grow outdoor flowers as houseplants
If traditional houseplants don’t interest you, consider flowering plants generally grown outdoor. These include geraniums, impatiens and begonias.
If you have a balcony or patio, give these plants a summer outdoors, then bring them inside to enjoy through the colder months. Or you could keep them inside year-round. For the latter, make sure they get plenty of light from a bright window, or purchase full-spectrum LED light bulbs to provide supplemental light. Use a timer to turn the lights on and off.
Set up a hydroponic garden
Depending on your space, you could set up a hydroponic garden in your apartment. Hydroponic systems grow plants in circulating water, not soil. Sizes range from table-top-sized to larger setups.
Most hydroponic kits also include grow lights. Specialised seed pods making it easy for beginners to grow food indoors.
