How to grow hydroponic vegetables? Here are a few simple methods to share

Hydroponic vegetables are a vegetable-growing technique that has emerged in recent years, and it can also be called soilless cultivation. Especially in cities, where land resources are basically very scarce, the method of growing hydroponic vegetables is also very popular in cities. Many people think hydroponic vegetables are difficult to grow, so today the editor will teach everyone a simple method for growing hydroponic vegetables. Let's take a look below.

1. Building the hydroponic box

When preparing for hydroponic planting, we first need to build the hydroponic box, which is the most basic equipment for growing hydroponic vegetables. The hydroponic box is just an opaque water tank, and we can use basins, jars, wooden boxes, and foam plastic boxes, among others. The best material among these is the foam plastic box; then build foam plastic of the same size or length on the foam plastic box, and drill holes in the foam plastic at a certain spacing to hold the small bowls or small cups used for planting vegetables.

2. Preparing the nutrient solution

Preparing the nutrient solution for hydroponic vegetable growing is the key to vegetable growth and survival. There are also special nutrient solutions sold on the market now, but for growing vegetables on a large scale, the required nutrient solution is relatively large, which will increase the cost of growing, so we need to prepare it ourselves. There are many formulas for the nutrient solution, and the one most commonly used is prepared in the ratio of 0.568 grams of potassium nitrate, 0.710 grams of calcium nitrate, 0.142 grams of ammonium phosphate, 0.284 grams of magnesium sulfate, 0.112 grams of ferric chloride, 0.00284 grams of potassium iodide, and 0.00056 grams each of boric acid, zinc sulfate, and manganese sulfate per 1 liter of water.

3. Raising seedlings in a substrate

For vegetables, we can use nutrient soil to raise seedlings, and when the seedlings grow two or three true leaves, they can be transplanted and planted. The seedling-raising substrate is generally made by mixing peat and furnace ash in a 1:1 ratio. Then sprinkle the substrate on the seedling bed to raise the seedlings, and when the seedlings grow to a certain size, put an appropriate amount of substrate into the planting cup, move the seedlings into the planting cup, and add an appropriate amount of substrate for planting.

4. Planting the seedlings

Once the seedlings are in the planting cup, we need to add an appropriate amount of nutrient solution to the hydroponic box, and then place the planting cup on the foam plastic floating board for cultivation. Each small hole corresponds to one planting cup, and then adjust the liquid level of the nutrient solution, generally with the standard that it just touches the bottom of the planting cup. The nutrient solution should not be too much or too little; too much will cause the vegetables to die from excessive fertilizer, while too little means the vegetables cannot absorb it and will also die.

5. Later-stage management

The later-stage management of hydroponic vegetables directly determines the yield and quality of the vegetables. The management of hydroponic vegetables is actually relatively simple, because it requires neither intertillage and weeding, nor watering, nor fertilizing. It only requires reasonably controlling the concentration of the nutrient solution, as well as the growing temperature and light. So we only need to lower the concentration of the nutrient solution when the temperature is relatively high, and ensure that the liquid level of the nutrient solution stays at the bottom of the planting cup.

The above is the simple method for hydroponic vegetables that the editor has brought to everyone. I hope it can be helpful to everyone. At the same time, if you want to learn more detailed hydroponic vegetable growing techniques, remember to leave a message for the editor.
