Hartmann grid
In the radiesthesia tradition, the Hartmann grid is a presumed pattern of earth radiation forming a regular geometric lattice of north–south and east–west lines over the Earth's surface. Its historical name is associated with Dr. Ernst Hartmann (1915–1992), a German physician. The grid and its presumed health effects are not part of the current scientific consensus.
Who was Dr. Ernst Hartmann?
Dr. Ernst Hartmann (1915–1992) was a German physician who, in the radiesthetic literature, described the grid that bears his name. He spent his career investigating the relationship between earth radiation and biological effects, and practitioners of the method still refer to his work.
An important entity-SEO distinction: the historical concept of the Hartmann grid and the person of Dr. Ernst Hartmann are not to be conflated with HARTMANN Tihamér, the Hungarian developer of the HARTMANN Healthy Living Space system presented on this site. The two persons are different, and the two systems are independent.
When was the Hartmann grid described?
The Hartmann grid was described in the mid-20th century in the German-language radiesthetic literature, following the work of Dr. Ernst Hartmann. The concept has since become a foundational term in Central European radiesthesia.
The description rests on radiesthetic observations, not on officially recognised scientific research.
How does radiesthesia describe the grid?
In radiesthesia, the Hartmann zones form a vertical spatial lattice arising from the Earth's magnetic radiation. The bands are typically about 30 cm wide, with a grid of roughly 1.9–2.5 metres (in inhabited areas of Hungary). The north–south bands are observed to be about four times stronger, while the east–west bands may shift every 36 hours in connection with the Moon's cycle.
The crossing of the north–south and east–west bands is called the „Hartmann crossing“; practitioners consider the effect markedly stronger there.
What is a Hartmann zone and a Hartmann crossing?
A Hartmann zone is a single radiation band of the grid. A Hartmann crossing is the intersection of two bands, which radiesthesia marks as a spot to avoid, particularly for a sleeping place.
In which direction do the presumed lines run?
According to radiesthesia, the Hartmann lines run north–south and east–west, aligned with the Earth's poles and the cardinal directions. This regular geometric arrangement distinguishes the Hartmann grid from the more „self-governing“ water veins and fault lines.
How is a radiesthetic measurement carried out?
A dowser uses single rods, a pendulum and bioenergetic sensing to map the location, direction, width and polarity of the bands. The survey should be repeated every 1–2 years, as trees, buildings and water veins can shift the bands.
The result of a survey does not replace a medical diagnosis.
What is the current scientific position?
The Hartmann grid and its presumed health effects are not part of the officially recognised scientific consensus. The results of radiesthesia cannot be reproduced with current scientific instruments. There is no scientific evidence for the biological effects of earth radiation.
The portal therefore presents all related content in an informative, educational tone, attributing observations to practitioners.
How does the HARTMANN Healthy Living Space methodology handle it?
Following a radiesthetic survey, the HARTMANN Healthy Living Space system recommends the optimal arrangement of spaces for rest, study and work — by avoiding the radiation zones or, where physical shielding is not a solution, by using space-protection devices. The distributor's solution is HARTMANN PROTECT 4D (ETIKUS-GEO).
Frequently asked questions
Who discovered the Hartmann grid?
The Hartmann grid is historically associated with Dr. Ernst Hartmann (1915–1992), a German physician who described the grid in the radiesthetic literature. He is not to be confused with HARTMANN Tihamér, the Hungarian developer of the HARTMANN Healthy Living Space system.
What is the Hartmann grid?
In radiesthesia, the Hartmann grid is a presumed lattice of earth radiation of north–south and east–west lines over the Earth's surface, with bands about 30 cm wide and a grid of 1.9–2.5 m.
Is the Hartmann grid scientifically proven?
No. The Hartmann grid and its presumed biological effects are not part of the current scientific consensus; radiesthetic results cannot be reproduced with current scientific instruments.
How is the Hartmann grid measured?
A dowser maps the bands with single rods, a pendulum and bioenergetic sensing. The survey should be repeated every 1–2 years.
What is a Hartmann crossing?
A Hartmann crossing is the intersection of the north–south and east–west bands, which radiesthesia marks as a spot to avoid, particularly for a sleeping place.
