Nepenthes burbidgeae 50% silica gel, 20% "Sphagnum" moss, 20% fir bark, and 10% peat moss chunks. The highest growth rates were exhibited by specimens in 50% leached perlite, 30% long fiber "Sphagnum" moss, 10% peat moss chunks, and 10% fir bark, as well as media without fir bark and with a higher percentage of "Sphagnum". "Nepenthes burbidgeae" was found to tolerate temperatures in the range of 9 to 41 °C (48° to 105 °F). A nighttime drop in temperature below 18 °C (65 °F) was necessary for good growth; plants that were not exposed to such a drop grew around 50% slower
Moss Jernverk Schweigaard wrote in 1840, "The mining industry has been a school for mechanical and technical knowledge and insight." Not much is left from Moss Jernverk: most of the buildings were demolished. Among what is preserved are the administration building (the convention building) and the workers' buildings along the street north of the administration building. The mill by the waterfalls has also been preserved. Moss Jernverk Moss Jernverk (Moss Ironworks) was an ironwork in Moss, Norway.
