Mary takes care of lighting, spectrum, day-night cycle, temperature, humidity, season simulation, fine-tuning growing conditions, but since you probably don't have a water hose in your living room, you will need to add water in the water reservoir yourself. The app will tell you when to do that, and when to fill in the nutrients. Nutrient concentration and pH level sensors are prone to miscalculation since they will be submerged in water 24/7, so we decided to regulate that by providing different nutrients packages for different kinds/strains of plants.
