Salinity is a game mechanic of the game Cell Lab, that appears in every substrate of the game and can be changed in Experimental Plates.
Sets the amount of salt that will be in the substrate. Substrates with low salinity will force cells to spend greater amounts of energy keeping their salt-balance, while a high Salinity will let them survive longer without any energy source.
It directly affects how much energy cells use in any given time. For example in a substrate with no light and min Salinity, a Photocyte placed from the Genome Editor will die in ~2,8h, while in the same substrate but with max Salinity, it will be able to survive ~39,6h
