The right amount of water for your plants

This solar drip system, sometimes called a "Kondenskompressor," cuts water usage by up to 90%. In conventional watering, much is lost to evaporation or runoff. Here, every drop counts—even brackish or seawater works effectively.

How to make a solar irrigator yourself?

Save Water This Summer: Build a DIY Solar Drip Irrigator with Recycled Bottles

The setup is straightforward: Place a 1.5-liter plastic bottle (recycled and cut in half, filled with water) at the base of each plant. Top it with a 5-liter bottle (also halved, cap intact). It functions like a mini greenhouse.

Sun heats the water, causing evaporation that condenses on the larger bottle's walls and drips slowly into the soil—pre-covered with straw to prevent evaporation. This replicates the natural water cycle, minimizing waste and reducing water needs tenfold.

Watering technique for everyone?

Ideal for small gardens and veggie patches—not large-scale farming. Popular in hot, arid regions, it thrives with minimal sunlight, making it versatile for various climates and a smart ally for sustainable gardening.

Only 1 liter of water for 7 weeks

Per the experts behind this method, use just 1 to 1.5 liters per plant for up to 7 weeks. After years of daily watering my own plot, this efficiency is game-changing—I'm implementing it this season.

Go on holiday with peace of mind

Imagine vacations without worrying about your plants or asking neighbors for help. With 7 weeks of coverage, you can relax stress-free.

It also works with seawater

Check this video tutorial for a clear demo—it excels with seawater too. Evaporation leaves salt behind, delivering pure moisture like ocean-formed rain.
