If you’re an herb lover and looking for a way to grow your favorite herbs year-round, DIY indoor hydroponic systems offer a fantastic solution.

Hydroponics, the practice of growing plants in nutrient-rich water instead of soil, is not only a space-saving technique but also ensures faster plant growth and a higher yield.

From aromatic basil to flavorful parsley, these systems make it easier than ever to cultivate your herbs indoors with minimal fuss.

Creating your own hydroponic systems for herbs at home can be both affordable and highly rewarding. Whether you’re new to hydroponics or an experienced grower, there’s a DIY hydroponic system for every skill level and space.

Here are 21 ingenious DIY hydroponic systems designed specifically for herb lovers looking to transform their indoor spaces into lush, aromatic herb gardens.

1. Kratky Method Hydroponic System

The Kratky Method is a simple, passive hydroponic system that works well for growing herbs like basil, mint, and oregano. This method doesn’t require a pump or aeration system.

Instead, the plants sit in containers with their roots submerged in water, which naturally wicks up to nourish the plants.

Features:

• Passive system with no pump or air stone required
• Perfect for leafy herbs like basil and mint
• Easy setup with minimal maintenance

2. Deep Water Culture (DWC) System

A Deep Water Culture (DWC) system is one of the most popular hydroponic setups. Plants are suspended in water with their roots submerged in nutrient-rich solution. This method is ideal for herbs that need consistent access to water, such as basil, cilantro, and parsley.

Features:

• Roots submerged in nutrient-rich water for optimal growth
• Suitable for high water-demand herbs
• Requires air stones and a water pump for oxygenation

3. Wicking Hydroponic System

The wicking hydroponic system uses a wick to draw water up from a reservoir to the plant roots. It’s a low-maintenance, passive system that works wonders for growing herbs like basil, thyme, and oregano. The wick ensures the plant roots remain moist without being submerged in water.

Features:

• Uses wicking fabric to deliver water and nutrients
• No pumps or electricity required for operation
• Great for low-maintenance herb gardens

4. Aquaponics System for Herbs

The aquaponics system integrates hydroponics and aquaculture, creating a self-sustaining environment where fish waste provides nutrients for plants, while the plants filter and clean the water for the fish. This eco-friendly system is ideal for growing herbs like mint, basil, and chives.

Features:

• Eco-friendly system combining plants and fish
• Great for growing herbs and small vegetables
• Requires fish tanks and a filtration system

5. Tower Hydroponic System

The tower hydroponic system uses vertical space to grow herbs, making it perfect for small indoor areas. This system involves stacking multiple containers or PVC pipes, allowing you to grow several herbs like parsley, rosemary, and cilantro in one compact unit.

Features:

• Vertical design maximizes space efficiency
• Easy to build with PVC pipes and plastic containers
• Great for growing multiple herbs in a small space

6. Ebb and Flow Hydroponic System

The ebb and flow hydroponic system floods the plants’ roots with nutrient-rich water before draining it away. This cyclical process provides herbs like oregano, mint, and chives with ample nutrients while preventing the roots from sitting in stagnant water.

Features:

• Flooding and draining cycle improves nutrient uptake
• Ideal for herbs that prefer intermittent watering like mint and oregano
• Requires a water pump and timer

7. Nutrient Film Technique (NFT) System

The NFT (Nutrient Film Technique) system is perfect for herbs like basil, parsley, and thyme that require consistent access to nutrients. It works by circulating a thin film of water across the plant roots, ensuring constant nutrient supply.

Features:

• Thin film of nutrient solution continuously flows over the roots
• Ideal for leafy herbs and small plants
• Works well with PVC pipes and slotted channels

8. PVC Pipe Hydroponic System

A PVC pipe hydroponic system is one of the most affordable DIY hydroponic setups. By cutting PVC pipes into horizontal or vertical sections, you can create a simple system that supports a variety of herbs, including mint, basil, and cilantro. The pipes carry the nutrient solution to the plant roots, ensuring they grow strong and healthy.

Features:

• Simple to build using PVC pipes and plastic containers
• Can be configured horizontally or vertically
• Supports various herbs like basil and oregano

9. Bucket System Hydroponics

The bucket system is one of the simplest hydroponic methods to grow herbs indoors. In this setup, plants grow in a bucket filled with a nutrient solution, while an air stone provides oxygen to the roots. It’s an easy, low-cost way to grow parsley, basil, and cilantro.

Features:

• Bucket-based system with easy access to plants
• Requires air stones and a water pump
• Great for medium-sized herb plants

10. Self-Watering Hydroponic Planters

If you’re short on space, self-watering hydroponic planters are a fantastic DIY option. These planters use a built-in reservoir and wicking system to keep your herbs like basil, parsley, and thyme watered without constant attention.

Features:

• Self-watering design for low-maintenance growth
• Ideal for growing small herb plants
• Easy to build using plastic containers and wicking material

11. Hanging Hydroponic Garden

A hanging hydroponic garden is a creative way to grow herbs like mint, parsley, and basil in small spaces. By repurposing old plastic bottles, you can create a vertical garden that saves floor space while allowing you to grow your favorite herbs.

Features:

• Hanging design saves space and adds vertical greenery
• Made from upcycled plastic bottles
• Great for small herb plants like mint and basil

12. Hydroponic Greenhouse

Building a mini hydroponic greenhouse is a great way to create a controlled environment for your indoor herb garden. Use a small plastic greenhouse and add a hydroponic system inside, such as a deep water culture or NFT system, to grow herbs like oregano, chives, and parsley.

Features:

• Controlled environment for optimal growth
• Combines greenhouse conditions with hydroponic techniques
• Perfect for growing multiple herbs

13. DIY Aeroponic System

An aeroponic system suspends plant roots in the air, misting them with nutrient-rich water. This system is perfect for growing fast-growing herbs like basil, cilantro, and parsley, and it can be made with PVC pipes, misting nozzles, and a water pump.

Features:

• Mist delivers nutrients directly to the plant roots
• Ideal for growing fast-growing herbs
• Requires a water pump and misting system
