How To Grow Vegetables Indoors Without Sunlight
If you are thinking about growing vegetables indoors without sunlight, there are plenty of solutions for beginners or experienced farmers.
You will need to consider all of the conditions a plant requires for growth and recreate these conditions using artificial means.
All vegetables are photosynthetic. This means that they convert the energy from light into food. So one important consideration when growing vegetables indoors is providing a replacement for sunlight.
Each vegetable requires different amounts of sunlight to grow efficiently. Lettuce and other leafy greens require less light to grow, while tomatoes need high levels of light.
LED lighting is the best choice for growing most vegetables indoors. LED lights provide more light at a lower cost while not producing too much heat.
Like outdoor plants, you will need to plant your vegetables in soil or alternative growth medium so that the roots can feed from the nutrients.
Topsoil is rich with all the nutrients a plant will need, created naturally from insect activity and worm castings.
Potting Mix Soil
You can purchase potting mix which is specially created for indoor growing. A potting mix includes soil mixed with perlite for aeration. The aerator helps the plants to breathe and allows for better water drainage.
Compost offers all the nutrition our plants need for indoor growing. Compost is created from garden waste and household waste after being left to break down naturally.
If you have space to begin a compost pile, you can create free soil for growing your vegetables and fruit from household scraps.
A hydroponic system allows you to grow vegetables indoors under lights but without the need for soil.
With hydroponics, the liquid flows directly to the roots, containing all the nutrients the plant requires.
In a hydroponic system, the plants need to be placed in a growing medium such as perlite, coir, clay pellets or rock wool to support the plant growth.
Types of Grow Lights Used for Growing Vegetables
The three main types of light for growing vegetables indoors are fluorescent lighting, high-pressure sodium lights or LED lights.
Fluorescent lighting offers a range of intensities and can be fitted into a regular light socket.
Florescent light bulbs are able to fit in small places. They are available as either thin tubular shaped bulbs or compact fluorescent lighting (CFLs).
CFL lights are one of the least expensive options for beginners who can’t afford the more efficient LED option.
High-Pressure Sodium Lights
If you use high-pressure sodium lights (HPS lights) for growing food, they need to be set further away from the plants. HPS lighting is a higher cost growing light than other options.
LED Lights are the most efficient light for growing vegetables indoors.
LED lighting is popular with indoor growers as they produce little heat, so won’t affect the temperature of the growing environment.
