But there are some things one has to consider while growing plants indoors may have to take care of the sunlight or the watering of plants.

If all this sound interesting, but wonder on “How to grow vegetables indoors without sunlight?” or more generally “How to grow vegetables indoors?”, then this article we help you with answering these questions.


Water is essential for life and this necessity extends for plants as well. They will require you to water them appropriately. Plants growing in a pot indoors are more likely to dry out than the ones outside. For this reason, you will need to ensure that your indoor plants receive appropriate water. Different plants have different requirements, but it is generally considered a bad idea to provide too much water for a plant as this extra water can cause rotting of plants. You can feel the soil of the pot to determine if it is moist enough or if it requires more water (or less, as the case may be).


Humidity in the air will affect the growth of your plants, especially the ones indoors. Indoor plants will depend on you to control the humidity available to them. In low humidity places for instances having centrally heated houses or drier environments, you will need to pay special attention to it. In low humidity your plants may turn brown and start losing their leaves. This can be dealt with by placing a water tray or bowl near your plant or spraying some water on them.


Regulating the right temperature for your plants is also essential to improve their growth. Generally, plants prefer a temperature range between 18-23°C. If you go above this range and make it too hot for the plant, they will grow weaker and smaller. If the temperature is too low they will lose leaves. Temperature may be adjusted using artificial light, which brings us to our next point.


Plants will need sunlight to grow and mostly a window should suffice. Sunlight is necessary for the process of photosynthesize and the survival of plants. Sunlight is special and has a particular wavelength. Plants have evolved over millennia to convert this sunlight into food. Your ordinary light from a bulb is not going to work. You can purchase special lights that are designed to grow vegetables indoors without sunlight.

Plants would generally require from 10 – 14 hours per day of this artificial light to make their food. If you have set up plants on shelves, then you have to be careful that the sunlight reaches all plants as best as possible. There are different types of these lights available. Generally they are of the following types;

High Intensity Discharge Bulbs are quite efficient sources of light as they can produce more output using relatively lower input, relative to other methods. This efficiency comes at a cost as they are generally more expensive.

Fluorescent Lights are relatively cheaper than HIDs but are more suitable for plants that don’t have high demands of light. These are widely available at most stores that deal with garden supplies.

Incandescent Lamps are cheap sources of artificial light for your indoor garden (or plants). They are also easier to acquire than other sources mentioned a fore.

Suitable Plants

Besides providing these conditions, it is also necessary to choose your plants wisely. Some plants are more suitable for indoor gardens while others demand conditions that are quite difficult to reproduce indoors.

As a rule of thumb, plants that are used for their roots will often require more sunlight than plants that are grown for their leaves or stems. We now look at some of the vegetables that are more suitable for growing indoors.

Salad greens such as endive, leaf lettuce and cress are relatively easier to grow indoors. Their lighting demands are less extreme.

Carrots, although they break the norm mentioned above, they are relatively easier to grow indoors.

Peas are a well-known vegetable used in a number of dishes. They are easier to grow indoors due to their less demanding nature.

Broccoli may not be your favorite food as a child, but adults know the health benefits associated with this vegetable. It is also on the list of vegetables that can be grown indoors.

Mushrooms can be grown indoors; some kits are available on the market that help you grow mushrooms indoors with relative ease and simplicity.

Tomatoes are a fruit that is commonly used in cooking. It is another example of plants that can be grown indoors.

Aside from the ones mentioned above, there are a number of other examples like beans, scallions, lemon, and garlic greens. Some herbs like parsley, oregano and rosemary are suitable for indoor gardens.  Blueberries and mandarin oranges are some of the fruit choices available for your indoor gardening needs.

Other things you may want to consider for your plants is providing them with nutrients and soil specially designed for growing indoor plants.
