Through a dealer in greenhouse solutions, we delivered a water storage tank for an orchid nursery in Cameron Highlands (Malaysia). In Cameron Highlands, during the entire year, the rain falls for 344 days and collects up to 3495 mm of precipitation. The prevailing tropical weather conditions make that a standard tensioned anti-algae cover will start sagging when high amounts of rainwater fall onto the cover.
On places with a lot of precipitation it is advised to place a center pole under the middle of the tensioned anti-algae cover. The center pole support the cover and the elevated positioning ensures that rain does not stay at the cover but slides along the cover down to the base.
