Drought in space is defined as the creation of not saline water measure and regolith measure that germination can not occur in the regolith by GMRS.
The creation of not saline water in space is as described in this post:https://unitednationssecuritycouncil.earth/?p=247
The salt https://en.wikipedia.org/wiki/Salt in space mix with the not salinated water created in space use to create salinated water in space.
The fact is that in space sunlight can be blocked from regolith and GMRS.Use the time of adequate sunlight for germination. Use the time of adequate sunlight to create a electrical charge to be able to create a spark. For the inadequate times of light use the energy produced by the creation of water to create the light.This is the essential information Sunlight,Regolith,GMRS,Water. https://en.wikipedia.org/wiki/Water
