Are you a green thumb looking to break the boredom and hassle that comes with growing vegetables in soil? Well, we’re sharing tons of information on what vegetables to grow indoors in hydroponics. 

What is a hydroponic vegetable garden?

This is a vegetable garden used to grow vegetables in a soilless medium. A nutrient-rich soilless medium is used instead of soil. Such media include sand, perlite, gravel, coconut coir, vermiculite, or nutrient-rich water in which the plant roots are suspended and receive the nutrients.

Hydroponic vegetable gardens use less water compared to soil-based gardens. All you need is containers or pots, water, plants, nutrients and a source of light. However, for an indoor vegetable garden, you need enough light. Most use artificial grow lights which helps to speed up growth rate.

Benefits of Growing Vegetables in Indoor Hydroponics

  • Vegetables that grow in indoor hydroponics grow bigger and faster, unlike those grown in soil, because there is reduced competition for nutrients and light with weeds and other unwanted plants.
  • Unlike their soil counterparts, vegetables grown in indoor hydroponics always give double the yields. This is because their nutrient uptake is faster than soil-grown crops which take a lot of time extending their roots to access nutrients.
  • Growing your vegetables in indoor hydroponics eliminates the chances of pests, diseases, and weeds that may attack your vegetables. Additionally, your vegetables will be guarded from damages caused by storms, drought, and floods because temperatures in this setup are controlled; hence, the plants only get what they require.
  • This method is very effective if you have limited space. The method is commonly used by city-dwellers who do not have enough space for farming.
  • Maintenance of vegetables grown in indoor hydroponics is hassle-free since the systems are automated, unlike growing them in soil gardens, which can be labor-intensive from seeding to harvesting.
  • Vegetable production in indoor hydroponics is all year round. Water is typically reused and recycled.
  • This method is very effective for people with mobility and physical challenges. The plants are not grown so low hence gardeners do not have to bend when working on the vegetables.

Cons of an Indoor Hydroponic Vegetable Garden

Some chemicals used to control pests and diseases have unpleasant smells that pose a risk to human health.

In most cases, if your house does not receive enough lighting, you have to buy or make your own grow lights stand to supplement the natural light.
