Basic Growing Methods Overview

There are several hydroponic methods, each with its benefits. These include:

  1. Wick Systems: Great for beginners, wick systems use a passive method to feed the roots.
  2. Water Culture: Known as the “lettuce raft” system, it’s perfect for leafy greens.
  3. Ebb and Flow: This system floods and drains the growing medium, ideal for many plants.
  4. Nutrient Film Technique (NFT): Plants’ roots are constantly fed by a flowing nutrient solution.
  5. Aeroponics: The most advanced, it sprays a fine nutrient solution on the roots.

Essential Components for Your DIY Hydroponics Setup

Starting a DIY hydroponic project means picking the right parts for a system that works well. At the core of any good hydroponic equipment setup are a few key pieces. These pieces work together to give plants the best conditions to grow.
