Mr. Truong Binh Son (HCMC) grows clean vegetables 'super easy', does not have to fertilize, water, improve the soil, weed the vegetables but still has a lush clean vegetable garden, eat all year round.
 |
| Mr. Truong Binh Son, 34 years old, living in Ho Chi Minh City, started to be interested in growing clean vegetables when his wife was pregnant. He learned about many different vegetable growing models, of which, Mr. Son was most impressed with the aeroponic model in space of NASA (National Aeronautics and Space Administration of the United States). |
 |
| He compiled information on NASA’s website, then used Google to learn and grasp the basic principles. Mr. Son said that before that, he had spent time in the ornamental plant business, so he grasped this knowledge quite quickly. |
 |
| The roots will be completely in the air in holes placed on the pillars. Each pillar he designed himself is about 1.9m high and has 56 holes for planting. |
 |
| Mr. Son said that the cost of making a vegetable growing pillar is about 2 - 2.5 million VND, including: pillar, solution tank, windproof base, lotus platform, pump, water pipe, and insulation tarpaulin. |
 |
| Hydroponic solution will be pumped from the solution tank below to the top, to the tree holes and then automatically returned to the tank. Mr. Son shared that there are many different types of hydroponic solutions on the market. He bought them and mixed them himself according to international standard formulas. |
 |
| Mr. Son's garden is 27 square meters wide, but the area for the pillars is only about 10 square meters. Each square meter can hold one vegetable pillar. Mr. Son believes that the aeroponic model is very suitable for urban households who want to use clean vegetables. This model can be applied to households with a natural light source for 5 hours a day. |
 |
| First, he sows the seeds in a thick layer of foam until they have 3-4 leaves. Then, the plants are placed in holes with hydroponic baskets, from here, the automatic aeroponic system will take care of the plants. The automatic pump will run when the water is low. |
 |
| Mr. Son affirmed that the aeroponics method is a superior method, overcoming many limitations of conventional vegetable growing methods. Initially, users have to invest in installing the system, however, after that, you will be quite "relaxed", not having to worry about watering, improving the soil, fertilizing, weeding... |
 |
| He used curtains to cover the pillars to keep out pests and diseases. |
 |
| In addition, the time for growing vegetables in aeroponics is about 30% shorter than other methods. Water spinach and mustard greens are edible after one month of planting. |
 |
| Although using 100% chemical nutrients, thanks to international standard mixing techniques, Mr. Son's vegetables still meet clean vegetable standards. This has been confirmed by him using the Russian Soeks Nitrate Residual Food Measuring Machine. |
 |
| Mr. Son started the aeroponic model in March 2016. After more than a month, his family harvested nearly 100 kg. He said that each harvest had to be divided among 8 households in the neighborhood. He estimated that a family of 5 only needed 4 vegetable growing poles to "eat all year round". |
