Sunlight is an essential part which plays an important role in photosynthesis as it provides the plant with energy. When you plan to grow vegetable plants on terrace or balcony, sunlight is the foremost important factor which you have to consider to get healthy growth of plants and good yield.
Following are the minimum hours of sunlight required for different plants:
Leafy Vegetables: 3 to 4 hours of Sunlight.
