Further:
Expirements in my garden (in Barneveld a dry place in the Netherlands)gave 
this summer very interesting results: 1liter/m2 every morning,enough for the 
growing of some plants like Eupatorium purpurea (1.5 m high).And this was no 
rain! In the period I made my experiments the daytemperature was about 27 
Celsius and night temperature 18 Celsius. 
I used 3 boxes, 2 boxes with the Eupatorium purpurea (about 30 centimeters 
deep) and between these 2 boxes an empty box for the measurements. Most of 
the dew was fallen from the Eupatorium purpurea in this box, a smaller box 
with no plants/trees in the neighbourhood gave about 0.15 deciliter/m2
