Hydroponic Systems Compared: Kratky vs NFT vs DWC
Choosing the right hydroponic system is key to a successful harvest. Here’s a breakdown of the three most popular systems we offer at miHydro.
1. Kratky Method
Best for: Beginners, leafy greens, herbs
How it works: Static reservoir of water; roots absorb nutrients as water level drops
Pros: No electricity, low maintenance
Cons: Not ideal for large or fruiting plants
2. NFT (Nutrient Film Technique)
Best for: Continuous production of lettuce, kale, herbs
How it works: A thin film of nutrient solution constantly flows over roots in a sloped channel
Pros: Efficient, scalable, high yield
Cons: Requires pump and power
3. DWC (Deep Water Culture)
Best for: Fruiting plants (tomatoes, peppers), fast-growing herbs
How it works: Plant roots are suspended in oxygenated nutrient solution
Pros: High oxygen = fast growth, easy to monitor
Cons: Needs an air pump
