What is hydroponics? It’s a method of growing plants without soil, using nutrient-rich water instead. This beginner’s guide from The Horticulture Company explains how it works and why it produces such impressive results.
A Simple Explanation for New Growers
Are you new to indoor gardening or looking for a more efficient way to grow your own herbs, vegetables, or leafy greens? This guide explains what hydroponics is, how it works, and why it’s one of the fastest-growing trends in home growing.
If you’ve ever searched “how to start hydroponics” or are looking for hydroponics for beginners, you’re in the right place.
What Is Hydroponics?
Hydroponics is a method of growing plants without soil. Instead, plants grow in a nutrient-rich water solution that delivers everything they need directly to their roots. These systems often use an inert growing medium like clay pebbles, coco coir, or rockwool to support the plants.
Without soil in the way, hydroponically grown plants often grow faster, healthier, and use less water—perfect for indoor environments or small spaces.

Why Hydroponics?
Here’s why thousands of home growers are making the switch to hydroponics:
- Faster growth rates
- Up to 90% less water usage (University of Arizona, 2020)
- No soil = fewer pests and diseases
- Ideal for indoor growing or tight spaces
- Year-round gardening with grow lights
Whether you’re growing in a kitchen cupboard or a dedicated grow tent, hydroponics offers complete control over your environment.
The 5 Main Types of Hydroponic Systems
Knowing your options makes it easier to choose a setup that fits your space and budget.
1. Deep Water Culture (DWC)
Simple and effective—plants float above a nutrient reservoir with their roots submerged. Add an air pump for oxygen.
2. Nutrient Film Technique (NFT)
A thin stream of nutrient water flows over the plant roots. Best for lightweight plants like salad greens.
3. Ebb & Flow (Flood and Drain)
Floods your plants with nutrients at set intervals, then drains away. Great for more advanced growers.
4. Wick System
A passive method that uses wicks to draw nutrients to the roots. Very low maintenance—perfect for beginners.
5. Aeroponics
Roots hang in the air and are misted with nutrients. High-tech and high-performing, but more complex.
Hydroponics for Beginners: What You’ll Need
Starting is easy with the right tools. Here’s a basic checklist:
- ✅ A hydroponic system (like a DWC or wick kit)
- ✅ A growing medium (e.g., clay pebbles, rockwool)
- ✅ Hydroponic nutrients
- ✅ A pH testing kit
- ✅ Grow lights (LEDs are best for indoor setups)
- ✅ A thermometer and humidity meter

How to Start Hydroponics at Home (Step-by-Step)
Here’s a simple guide for beginners:
- Pick your system – DWC is a great place to start.
- Choose easy plants – Lettuce, basil, spinach, and herbs are forgiving.
- Set up your space – A grow tent or corner with proper light and ventilation works well.
- Mix nutrients – Follow instructions on your nutrient solution.
- Adjust pH – Ideal range: 5.5–6.5.
- Check water temperature – Keep between 18–22°C.
- Maintain regularly – Check nutrient levels, pH, and plant health.
💡 Pro Tip: Add a pH control kit and nutrient measuring pen to your order for better results.
Common Mistakes to Avoid
Avoid these pitfalls as a new grower:
- ❌ Ignoring pH levels
- ❌ Using tap water without checking hardness or chlorine
- ❌ Overfeeding nutrients
- ❌ Insufficient lighting

Frequently Asked Questions
Hydroponics is a method of growing plants without soil, delivering nutrients directly to the roots via a water-based nutrient solution. Without needing to break down organic matter in soil, plants access nutrients immediately — which accelerates growth rates and gives growers precise control over plant nutrition from propagation through to harvest.
Hydroponics produces faster growth and heavier yields in a controlled environment — plants in well-managed hydro setups typically grow 20–30% faster than in soil under the same lighting. Soil is more forgiving for beginners and requires less equipment. Hydroponics rewards growers who can maintain consistent pH, EC, and environmental control.
Yes — hydroponic plants typically grow 20–30% faster than equivalent plants in soil under the same lighting. Nutrients are delivered directly to the root zone in a readily available form, so plants spend no energy breaking down organic matter or extending roots through dense growing medium to find food.
A basic hydroponic setup requires a growing system (such as a DWC bucket or NFT channel), grow tent, grow light, nutrient solution, pH meter, EC meter, and a timer. Starter kits combining these components are the most cost-effective entry point — a small but fully functional setup can be running for under £400.
