Hydroponics vs. Soil Culture: Which Is Better? Understanding the Differences in One Article
Have you ever hesitated over whether to grow your plants in soil or in water? Today we will give you a detailed introduction to the differences between these two methods, so you can easily master the essence of growing plants!
Growing Environment
Soil growing: It is like sending the plant back into the embrace of nature, and the types of soil are incredibly diverse. Loose leaf mold, fertile garden soil, and sandy loam with excellent drainage provide steady support for the plant's root system, allowing it to stretch out freely and take root deep down, just like having a safe harbor, so it can easily handle any disturbance from the outside.
Water growing: The plant's roots sit directly in nutrient solution or clean water, clean and transparent, so you can clearly see the condition of the roots. But this environment is rather "delicate": if the temperature, water quality, or nutrient solution concentration is even slightly off, the roots will "throw a tantrum," so it needs extra careful attention.
Water Management
Soil growing: Watering depends on the soil's water-holding capacity, whether the plant likes to drink a lot, and the weather conditions. Water thoroughly so every bit of root gets its fill, but never let water accumulate, or the roots will be smothered and unable to breathe. Succulents are drought-tolerant, so wait until the soil is completely dry before watering; pothos likes moisture, so water as soon as the soil surface dries.
Water growing: The water level is key, and you must keep an eye on it at all times. Change the water regularly to keep it clear and well oxygenated, otherwise algae will easily grow. In summer, when the plant is growing vigorously, or when the water quality is poor, change the water 1 - 2 times a week; in winter, when growth is slow,2 - 3 once every 2 weeks is enough. Add some nutrient solution when changing the water, and the plant will thrive.
Nutrient Supply
Soil growing: Fertilizing is like a long battle: base fertilizer lays the foundation before planting, and topdressing gives support during growth. Organic fertilizer and slow-release fertilizer improve the soil, while compound fertilizer and water-soluble fertilizer are added as needed, but too much fertilizer can burn the roots, so be careful.
Water growing: The nutrient solution is the plant's "energy drink," with nitrogen, phosphorus, potassium, and trace elements blended according to the formula. The concentration must be controlled precisely, generally 0.5‰ - 2‰, adjusted according to the plant's condition. Add an appropriate amount of nutrient solution each time you change the water, and the plant will be full of vitality, but if the ratio is wrong, the plant will be "malnourished" or "overfed."
Root Form
Soil growing: The roots are like strongmen, well developed and thick, with the main root desperately drilling into the soil, lateral roots spreading in all directions, and fine hair roots tightly gripping the soil to absorb nutrients. They are earthy yellow with a hint of brown, full of the smell of soil.
Water growing: The roots are like fairies in the water, slender and white, stretching freely in the water, with new roots like transparent silk threads. To breathe in the water, they even evolved aerenchyma. Isn't that amazing?
Pest and Disease Control
Soil growing: There are many pathogens and insect eggs in the soil, and root rot, leaf spot, aphids, and other problems often cause trouble. Control requires spraying, ventilation, sunlight, and soil disinfection, but pesticides must not be used carelessly, or they will pollute the environment and harm the plants.
Water growing: The environment is enclosed, so pests and diseases are relatively few, but poor water quality and poor ventilation can also cause problems, such as root rot, water mold, and mosquitoes. Keep the water clean, disinfect the container, and provide ventilation. If there are problems, use biological control or low-toxicity pesticides, which are gentle and effective.
