Does an Indoor Greenhouse Need Sun?

While it can benefit from natural sunlight, it is not absolutely necessary. You can use grow lights instead of natural sunlight to provide the plants with the light they need for photosynthesis.

Grow lights are specially designed to provide the appropriate light spectrum for plants and can be adjusted in terms of intensity and duration to meet the needs of different types of plants.

If your place yours near a window that receives ample sunlight, it can help supplement the artificial light and provide some natural light for your plants. Just be sure to monitor the temperature and humidity levels in your indoor greenhouse, as sunlight can increase the temperature and cause fluctuations in humidity levels.
