Hydroponics 101: Growing Without Soil

DDenver October 17, 2023 5:26 PM

You've probably heard about hydroponics, but what exactly is it? Well, hydroponics is a method of growing plants without soil. Instead, plants are grown in a nutrient-rich water solution. This form of gardening has gained popularity due to its numerous benefits such as requiring less space, allowing for year-round cultivation, and reducing water waste.

How Does Hydroponics Work?

In a hydroponic system, plants are supported by an inert medium such as perlite or coconut coir, and nutrients are delivered directly to their root system through water. This efficient delivery method allows plants to use less energy to find and break down food, leading to faster and more robust growth.

Types of Hydroponic Systems

There are six main types of hydroponic systems: Wick, Water Culture, Ebb and Flow (Flood & Drain), Drip (Recovery or Non-recovery), NFT (Nutrient Film Technique), and Aeroponic. The type of system you choose will depend on factors such as your budget, available space, and the types of plants you wish to grow.

Best Plants for Hydroponics

While you can grow almost any plant hydroponically, some plants are more suited for this method than others. Leafy greens like lettuce, spinach, and kale do particularly well in hydroponic systems. Herbs such as basil and dill are also great choices. For those with more experience, you can try growing tomatoes, cucumbers, or even strawberries.

Starting Hydroponics at Home

Setting up your own hydroponic system at home can be a fun and rewarding project. Here's a basic guide to get you started:

  1. Choose your system: Decide on the type of hydroponic system that best suits your needs and space.
  2. Select your plants: Choose plants that are well suited for hydroponic growth.
  3. Prepare the growing medium: Depending on your system, set up your inert growing medium.
  4. Mix your nutrient solution: Purchase a pre-made mix or make your own nutrient solution.
  5. Monitor and maintain: Regularly check the pH and nutrient levels of your solution, adjust lighting as needed, and ensure your plants are healthy.

Hydroponics vs Soil: A Comparison

Hydroponics Soil
Water usage Less water is needed as it's recycled within the system. More water is needed as it leaches out with soil.
Nutrient delivery Nutrients are delivered directly to the roots. Plants need to search for nutrients in the soil.
Space Compact setup allows for indoor growing. Requires more space, usually done outdoors.
Pests and diseases Lower risk as there's no soil to harbor pests. Higher risk due to pests in soil.
Growth rate Plants grow faster as they receive optimum nutrients. Growth rate is slower.

Final Thoughts

Hydroponics may seem daunting at first, but with a bit of practice, you’ll find it’s a highly rewarding and efficient method of gardening.
