All lovers of healthy eating are tempted by fresh green salads, which are already available all year round in the markets or on the stands of large hypermarkets. The question of what exactly we consume remains open. The hysteria over the nitrate content in vegetables, which until a few years ago disturbed the hosts' sleep, has subsided.
Even the warnings of English microbiologists about the risks of consuming pre-washed and packaged lettuce, which are freely distributed on the market, are not able to embarrass fans of fresh green salads.
There is now an easy and cheap way to eat fresh vegetables without worrying about your health. Even housewives who do not have a yard or a huge terrace can grow vegetables to diversify their daily menu.
No large space or expensive equipment is required. Just a few squares, glass or plastic containers, a little water and a lot of desire are enough.
Hydroponic cultivation of vegetables at home has become increasingly common in recent years. Also known as soilless, because the soil has been replaced by special nutrient solutions, it is a cheap and environmentally friendly alternative to buying and consuming vegetables of unclear origin and questionable quality.
Not all vegetables are suitable for soilless cultivation. Only some varieties of tomatoes and cucumbers are suitable for hydroponic cultivation. On the other hand, with this technology you will be able to enjoy lettuce, Chinese cabbage, leeks, green onions and even chicory or pineapples all year round.
The hydroponic plant consists only of a container in which an nutrient-enriched aqueous solution and a porous substance (eg styrofoam) will be poured to keep the plant above water when needed.
How to grow Chinese cabbage or lettuce at home through hydroponics
Cut the leaves of Chinese cabbage or lettuce near the cob. Pour water into a transparent container, no more than one finger, reaching only the bottom of the cut head. Add a few drops (4-5) of liquid organic fertilizer and place in direct sunlight.
Monitor the amount of water and top up if necessary. At each addition of water, add one or two drops of liquid organic fertilizer. After about one, two weeks you will notice how new leaves grow from the cobs grown in this way.
How to grow onions or leeks through hydroponics
The easiest way to grow onions or leeks is to simply put an onion root in a glass of water, making sure that the aqueous nutrient solution covers a maximum of ½ of the plant's roots. When you want to grow larger quantities of these vegetables, you can resort to the help of pieces of styrofoam, which you have previously drilled and carved.
Prick the individual onion or leek stalks in the styrofoam thus prepared and place them in a suitable container filled with nutrient-enriched water, again making sure that the water does not cover more than half of the roots. Place in the sun and monitor the amount of water, adding water and liquid organic fertilizer if necessary.

Ideas For Fresh Vegetables
Fresh vegetables are good for the body and can be drunk on an empty stomach. Then their effect is even greater. Fresh vegetables are useful for protection against many diseases because they contain many useful substances and vitamins. Cabbage juice is not very tasty, but after mixing it with a little carrot juice and 1 tablespoon of parsley juice, you get a delicious combination.
How To Keep Fresh Tomatoes Fresh Longer?
There are literally hundreds of types of tomatoes. The applications of juicy and tasty vegetables are even more - on cold sandwiches, in salads, for various dishes. Moreover, tomatoes are extremely useful. They contain real deposits of vitamins C, A and K, potassium (which controls heart rate and blood pressure) and manganese.
Fresh Fruits And Vegetables Instead Of Isolated Vitamins And Minerals
Over the years, we have learned that the human body is not designed to consume isolated nutrients and use them effectively. We need to take a whole palette of complementary natural nutrients. Lycopene, for example, is a phytonutrient found in tomatoes that is known to prevent prostate cancer.
Let's Keep The Vegetables Fresh For A Long Time
Vegetables are one of the main elements of a healthy diet. Everyone needs to know how to store and use them properly. Keeping your vegetables fresh is quite difficult. Every day some of the purchased ones go in the trash. In this way, you lose both health benefits and money.
Frozen Fruits And Vegetables - More Useful Than Fresh
Researchers from the Institute for Nutrition Research in the UK have come to an incredible conclusion: frozen fruits and vegetables contain many more nutrients than fresh. The reason lies in the fact that fresh fruits and vegetables do not reach the stalls as soon as they are picked, but only after a few days and due to this fact they lose many of their valuable substances.
