Cara Menanam Kangkung Tanpa Tanah

>Hello Sohib EditorOnline, welcome to our article on how to grow kangkung without soil. This method is a solution for those who want to cultivate vegetables but have limited space or urban areas without access to soil. Moreover, growing vegetables without soil is also an environmentally friendly solution that reduces water usage and fertilizer needs.

What is Hydroponic?

Hydroponics is the practice of growing plants without soil, using nutrient-rich water instead. This method has been used since ancient times and has since developed into a modern, effective and efficient way of cultivating plants. The principle of hydroponics is to provide plants with essential nutrients directly through nutrient solutions or substrates, without soil.

In hydroponic, the nutrients required by plants are dissolved in water and supplied to the plant roots through capillary action, ensuring that the plants receive the exact amount of nutrients required. This method requires less water, uses fewer pesticides and herbicides, and yields better crop results because there is no competition for nutrients from weeds and other plants.

What are the Benefits of Hydroponic?

There are many benefits of hydroponic, including:

Benefits Explanation
Less Water Usage Hydroponic uses up to 90% less water than traditional soil gardens because water is recycled within the system.
Higher Yield Hydroponic has a higher yield potential because it allows crops to grow faster and in a controlled environment.
No Pesticides or Herbicides With hydroponic, there is no need for pesticides or herbicides, so you can grow vegetables that are free from harmful chemicals.
No Soil Required Hydroponic eliminates the need for soil, which means you can grow vegetables in areas where soil is not available or contaminated.
Year-Round Growing Hydroponic allows year-round growing and reduces the dependence on seasonal weather changes.

How to Grow Kangkung Without Soil

If you want to grow kangkung without soil, you can try the following steps:

1. Prepare the Materials

The materials required for growing kangkung include:

  • Kangkung seedlings
  • Net pots or plastic containers
  • PVC pipes or other containers to hold the nutrient solution
  • Air pump
  • Air stone
  • Nutrient solution

2. Make the Hydroponic System

To make the hydroponic system, follow these steps:

  1. Drill holes in the PVC pipes or containers according to the size of the net pots.
  2. Fill the container with nutrient solution and insert the air stone.
  3. Connect the air pump to the air stone and switch it on.
  4. Insert the net pots with kangkung seedlings into the holes in the PVC pipes or containers.

3. Maintain the Hydroponic System

To maintain the hydroponic system, follow these guidelines:

  • Check the nutrient solution level regularly and add water or nutrient solution as required.
  • Check the pH level of the nutrient solution and adjust it to the appropriate level for kangkung growth.
  • Keep the air pump and air stone clean to ensure adequate oxygen supply to the plants.
  • Remove any dead or diseased plants immediately to prevent the spread of disease.

4. Harvest the Kangkung

Kangkung can be harvested when the leaves are approximately 20-30 cm long. To harvest the kangkung, simply cut the leaves off the plant with scissors or a sharp knife. The plants will continue to grow and produce new leaves as long as the hydroponic system is maintained.


1. What Nutrient Solution is best for Growing Kangkung?

For growing kangkung, a nutrient solution with a pH level between 5.5-6.5 is considered ideal. The nutrient solution should contain essential nutrients such as nitrogen, potassium, calcium, and magnesium, and trace elements such as iron and zinc.

2. How Often Should I Change the Nutrient Solution?

The nutrient solution should be changed every 2-3 weeks to ensure that the plants receive fresh and adequate nutrients.

3. Can I Grow Kangkung in Small Spaces?

Yes, hydroponic allows you to grow kangkung in small spaces such as balconies or terraces, and even indoors. You can use small containers or net pots and PVC pipes to create a vertical hydroponic system that maximizes space.

4. Is Kangkung Easy to Grow?

Yes, kangkung is relatively easy to grow and requires minimal attention. However, it is important to maintain the hydroponic system and provide adequate nutrients and oxygen to the plants.

5. Can I Use Other Vegetable Seeds in Hydroponic?

Yes, other vegetable seeds such as lettuce, spinach, and tomatoes can also be grown in hydroponic systems. However, different vegetables may require different nutrient solutions and growing conditions.


Growing kangkung without soil is a great way to cultivate vegetables in limited space and an environmentally friendly solution for reducing water usage and fertilizer needs. With hydroponic, you can grow kangkung year-round and avoid harmful pesticides and herbicides. Follow the steps outlined in this article, and you’ll be able to produce fresh and healthy kangkung at home.
