Kratky Hydroponics Where You Live

Kratky Hydroponics for Every Grow Space

Kratky Hydro shows how to make the Kratky method work in the space you actually have: a kitchen windowsill, a small apartment, a balcony, a shelf under grow lights, a greenhouse, a cabin with no power or a classroom. It is for home growers who want fresh greens and herbs without pumps, timers or soil.

What Kratky Hydro Covers

The Kratky method is passive hydroponics: a plant sits in a net cup above a container of nutrient solution, and as it drinks, the water level drops and the roots grow down after it. There is no pump and no electricity. New to the method itself? Start with the full guide at Kratky Method of Hydroponics.

The method is simple, but every space changes the details. Light, heat, cold, rain, room to spare and how often you can check on your plants all decide what you can grow and which container to use. Each Kratky Hydro guide takes one kind of grow space and works through those details.

We grow this way ourselves: in mason jars indoors all year, then moving plants outside when the weather warms up. More about Kratky Hydro.

Why Kratky Fits Small and Simple Spaces

No Pumps or Power

Nothing to plug in, so it works anywhere a container fits, including places without an outlet.

Small Footprint

One jar or tub per plant. A windowsill or a single shelf is enough to start.

Low Upkeep

Most leafy greens and herbs can grow from planting to harvest without topping up the container.

Indoors or Out

Grow inside under a window or lights through the cold months, then move plants outdoors when it warms up.

Where Kratky Works

Indoors

Kitchen windowsills, small apartments, and closets or basements under grow lights.

Outdoors

Balconies, patios and greenhouses, where heat, rain and algae need extra care.

Special Situations

Off-grid cabins and places without electricity, and classroom or kids' projects.
