Growing fresh vegetables indoors has become an important part of healthy living. Before you start indoor growing you have to understand the plant’s need for light, otherwise you may get stunted plants. Because light is the food of plants, plants cannot photosynthesize without adequate light sources, which can lead to slow growth or simply death. As a grower, knowing the time of light needed to grow your plants is your first step to start growing.

How long will it take for me to harvest the vegetables? This article answers questions about indoor gardening, including light schedule for plant growth, optimal growing temperatures and growing cycles. Ten common indoor vegetables are used as examples.

How Long Should Grow Lights Be On For Vegetables?
The amount of light your vegetables need is the amount of time your plant lights are on. And the first thing we need to know is that indoor and outdoor growing environments differ greatly, so plants grown under indoor lights require more light hours than the same plants grown outdoors. In general, plants grown under grow lights need at least 12 hours of light per day, but no more than 18 hours; plants also need at least 6 hours of rest per day.
Among the above vegetables, Microgreens requires the shortest amount of light, with 4-6 hours of light per day being sufficient; Carrot, Mushroom, Potatoes, Peas and Radishes require about 8-12 hours of light per day; Green Onions, Hot Peppers and Lettuce require more light, with 12-16 hours of light per day; and the one that needs the most light is tomatoes, which need 16-18 hours of light per day to meet thriving growth.
How Long Does It Take To Grow Them?
The growth cycle is also one of the important information you need to know, it will determine how long it will take you to be able to taste fresh vegetables. Among these vegetables, Peas, Carrots, Mushrooms, Radishes, Lettuce and Microgreens only take 1-2 months to grow. Some vegetables take longer to grow, such as Potatoes, Green Onions, Hot Peppers and Tomatoes, which take 2-4 months to grow.
Don’t forget that the ambient temperature is also an important influencing factor. The above vegetables will grow healthily between 45-85°F.
