Ergo I immediately bought this good-sized 'hamster cage' and put into the car in front of the rear seats.
It takes up to 2 months before the first drops of water landing in the collecting vessel. Depending on the humidity and rain in the winter relatively quickly then takes more water to which I just cant in a gully. Eventually the granulate has collapsed into itself, and swimming in the water crystals. Then it is time to get a refill.
From the beginning of December 2013 to the end of April 2014, the first filling has held. Then I needed a new package and bought at the hardware store a UHU package - that was a mistake. The UHU granules fell faster in together as I could see.
Now I bought 3x1 kilo Humidry - a kilo should be sufficient until December 2014.
For all the impatient: The granulate takes up a lot of water before it emits liquid in the container! Just the same hamster cage after filling weigh, then after 4 weeks again - because it is amazed how the weight is changed by the stored water.
OK, so a hamster cage is not for everyone, but to me it is more important that the interior of my car is dry.
The stuff has my absolute recommendation for the use in the car
