1、 It's better to spray leaves or pour soil

Spraying leaves with nutrient solution is relatively better than watering soil, because the purpose of nutrient solution itself is to help the leaves grow more vigorous and green. Therefore, spraying nutrient solution directly on the leaves will help the plant leaves absorb nutrients more directly and quickly. The method of watering soil with nutrient solution is more indirect, and the time for leaves to receive nutrients is also slower. Due to the high concentration of nutrient solution, you can't use too much when using it, so as not to cause root burning or leaf burning. After spraying leaves, the remaining nutrient solution can be used to irrigate the root system of the plant to make the best use of everything

2、 Usage of some common plants

1. Common plants like us are green pineapple, which belongs to foliage plants. Diluted nutrient solution can be sprayed directly on the back of leaves or branches, so that the leaf surface will absorb well and make the leaves brighter

2. The leaves of Fugui bamboo can also be used for leaf spraying. You can drop a few drops of it into the watering can and mix it with water to spray leaves. However, if it is hydroponics, it is better to directly drip it into water for maintenance
