| Table 2: Temperatures and RH% during the course of the experiment, from Mar 22nd to Apr. 28th 2002. Increase of Azolla biomass is somewhat dependent on air humidity as at less than 60% of relative humidity, the fern becomes dehydrated and fragile. During the experiment, the RH% dipped below this critical level for a brief period. | |||||||||||||||||||||||||||||||||||||||||||||
