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.
