What is the Kratky method?

A passive hydroponic method with no pumps or electricity. Plants sit in net pots above nutrient solution. As water level drops, roots grow into the air gap for oxygen. Dead simple and surprisingly effective.

What can you grow with the Kratky method?

Leafy greens excel - lettuce, spinach, arugula, kale. Herbs like basil, cilantro, and parsley work brilliantly. Small fruiting plants like cherry tomatoes and peppers grow well too, though they need topping up.

Does the Kratky method actually work?

Absolutely. You can grow 6 lettuce heads in 5 weeks in a plastic storage container. No maintenance beyond initial setup. The key is matching container size to plant needs - bigger containers for longer crops.
