The hydroponic vegetable farm of nearly 1 hectare of Mr. Phan Tuan Linh's family (37 years old, Da Lat Lam Dong) yields up to 15 crops each year. The products are very clean and do not need to be washed.
 |
Mr. Linh's family is growing 7 main types of lettuce using hydroponics. |
 |
Many other vegetables such as green onions, mustard greens, herbs... are also being grown on this farm. |
 |
Unlike traditional farming, hydroponic vegetables must be incubated in a substrate containing crushed coconut fiber before being planted. |
 |
When the seedlings develop 3-4 young leaves, they will be planted in a trellis made of specially designed plastic bars for water to flow inside at least 70 cm above the ground to completely isolate them from pathogens that appear in the soil. |
 |
The survival rate of hydroponic vegetables when planted is absolute. When the vegetable plants take root, they will cling to these plastic bars, absorbing nutrients from the water. |
 |
Hydroponic vegetables grow very quickly because they are provided with adequate nutrients and the greenhouse environment is controlled at an ideal temperature. |
 |
Nutrients in the water are evenly distributed so hydroponic vegetables grow almost "ten plants as one", in rows. |
 |
Mr. Phan Tuan Linh said that hydroponic vegetables grown on substrate can be harvested after 25 days. |
 |
Like that, each year with this new vegetable growing method, gardeners can grow up to 15 crops, while traditional farming only produces 3-4 crops. |
 |
The entire ground is covered with clean cement to completely isolate potential pathogens in the soil and ensure environmental hygiene during production. The greenhouse system is designed to be high and airy, creating the best conditions for hydroponic vegetables to grow and develop. |
 |
Because they are grown completely isolated from the ground and the outside environment, hydroponic vegetables are almost disease-free, and gardeners do not have to use chemicals to prevent pests. In this hydroponic vegetable farm, there are also many traps to catch flies, mosquitoes, ants, etc. |
 |
Vegetables grown using hydroponics have one thing in common: they are of very high quality, fresh, and can be stored for a long time because the whole root system is harvested. |
 |
Currently, all types of clean vegetables grown using this hydroponic method are being sold by Mr. Linh's family at 35,000-45,000 VND/kg. In the near future, he will open a stall to provide clean vegetables to the people of Da Lat City. |
 |
The farm is also open to visitors for free. Many visitors often pick off each leaf of vegetable and eat it right in the garden without having to wash it with clean water. |
 |
Vegetable consumption markets are supermarkets and restaurants in Da Lat and Ho Chi Minh City. |
