Plants require a variety of nutrients and minerals in order to grow strong and healthy. Plants make food using a biochemical process and elements such as phosphorous, nitrogen and potassium are essential. Other nutrients such as magnesium, calcium and iron aid to make you plant even healthier.

Nitrogen is an important part of growing leaves. The air is about 79% nitrogen, but plants will still need a supplement of it to grow. The molecule of N2 in the air is not very stable and plants can't break apart the compound to find the single atom. Phosphorus is also very important for root growth. Potassium, on the other hand, helps to fight diseases since it is a big part of enzyme formation.

There are other elements that are very important to the life and health of your hydroponic plant. Calcium is necessary to help build the cell walls and also will help to deliver ions to various parts of the plant. Chlorine is a part of chlorophyll and is a very big part of photosynthesis. Iron, meanwhile, is a big factor of the hemoglobin molecule and is formed by plants and animals to help transport oxygen for cellular respiration.

You can find pre-made solutions that will give your plants the nutrients they need. Just like with anything, the right dosage is essential. You can find young plants that will need a specific dosage, while flowering plants will require a completely different amount.

Keeping the water and temperature can also be very important for your plants since this helps or hinders their feeding. You can find a range of solutions, but they should all be fed at room temperature level. The hydroponic plants themselves should also be in water that is room temperature for best results.

Dry plants need nutrients and nitrogen burning is possible. You can find the aeroponics, which is when one branch is grown in air and can suffer the problem of nitrogen burning.

If you get your water from the tap, leave the water overnight to allow chlorine to evaporate. Mineral water is preferable to distilled water as it contains calcium and other positive nutrients.

Keep the pH in the soil as neutral as possible to see the best results with your plants. You can keep your plants neutral to keep the water alkaline. A pinch of sulfuric acid can be added to ensure the water is a neutral pH. If you have very acidic water, you can make it more neutral pH with sodium hydroxide.

You can easily buy kits to help you check the pH level of the water used for hydroponics. Your hydroponic plants will be more sensitive to nutrient levels and can't self-regulate themselves like soil-based plants so you will need to keep an eye on your plants.
