How often do I need to re-fill my Osmogro® reservoir with water?
You can leave your houseplants unattended for 1 – 4 weeks or even longer, depending on the size or capacity of your water reservoir (e.g. plant pot saucers, ceramic and glass bowls, gardening, plant and windowsill trays, and even your sink or bath!). The Osmogro® reservoir holds about 400 ml of water. Remember, different indoor plants will have different watering requirements. Temperature and environment will also affect your houseplants’ watering needs.
