Why Choose Kratky for Peppers?

Simplicity at Its Best

The Kratky method requires no pumps or electricity, so there is little equipment to buy, set up or run.

Cost-Effective Growing

With minimal setup costs and no need for soil, this method is budget-friendly and efficient.

Roots Get Air and Water

As the plants drink, the water level drops and leaves an air gap, so the roots take in oxygen from the air and nutrients from the solution.

Low Daily Upkeep

There is no pump to run, but peppers grow for months. Plan a large reservoir or occasional top-ups.

Grow without soil

Introduction to Kratky Hydroponics

The Kratky hydroponic method is a passive way to grow plants, including peppers, without soil. This method relies on a passive system where plants are suspended above a nutrient-rich water reservoir, allowing their roots to absorb nutrients directly.

The Kratky method works most simply for short crops such as leafy greens. Peppers take far longer, so they need a larger reservoir or occasional top-ups of fresh nutrient solution. Kratky is also one of the best ways to start healthy pepper plants indoors, then harden them and plant them outdoors in soil. The Method page explains both.
