Not sure which setup is right for you?
Take Our QuizHydroponics is growing plants in water instead of soil. That's it. The technology has evolved, but the principle is simple: give roots what they need directly.
Why Hydroponics Works: In soil, plants spend energy growing roots to find water and nutrients. In hydroponics, everything comes directly to the roots. That saved energy goes into faster growth.
Hydroponic plants typically grow 30-50% faster than soil-grown equivalents. They use up to 90% less water. And you can grow year-round regardless of outdoor conditions.
What You Actually Need:
1. A container (anything that holds water) 2. Net pots or something to hold plants 3. Growing medium (clay pebbles, rockwool, or similar) 4. Nutrients (liquid fertiliser designed for hydroponics) 5. Light (window or grow light depending on location) 6. pH testing kit
That's the complete list. Everything else is optimisation.
Start Simple: The Kratky Method: Fill a container with nutrient solution. Place a plant in a net pot so roots touch the water. Leave an air gap. The plant grows.
No pumps, no timers, no complexity. Mason jars work. Storage boxes work. Start here.
Best First Crops:
Lettuce: Fast, forgiving, ready in 4-6 weeks. Perfect for learning.
Basil: Grows eagerly in hydroponics. One plant produces for months.
Spinach: Quick to harvest, regrows after cutting.
Avoid tomatoes and peppers initially. They need more light, more nutrients, and more attention. Graduate to them after success with greens.
Realistic Expectations: Your first attempt might fail. That's normal. Seeds might not germinate. Roots might rot. pH might drift. Each failure teaches something.
Most people see good results by their third or fourth grow. Give yourself permission to learn.
The Investment: A basic Kratky setup costs under £50. Add a grow light (around £50-80) if you lack natural light. You can harvest fresh lettuce and herbs within 6 weeks of starting.
Next Steps: Read our pH guide. pH problems cause most beginner failures. Once you understand pH, everything else becomes easier.

Start the QuizFrequently Asked Questions
Is hydroponics difficult for beginners?
Not at all. Start with the Kratky method - literally just a container, nutrients, and seeds. No electricity, no pumps. Once you understand pH and nutrients, you can grow herbs easier than in soil.
What should I grow first in hydroponics?
Lettuce and basil are perfect starter crops. They grow fast (4-6 weeks), tolerate beginner mistakes, and thrive in simple systems. Avoid tomatoes and peppers initially - they need more complex setups.
How much does it cost to start hydroponics UK?
Basic Kratky setup: £30-50 total. Simple DWC system with air pump: £80-120. Full grow tent setup with lights: £400-600. Start small, learn the basics, then scale up.
