Hydroponic liquid source
Hydroponic liquid will saturate the 5x5 node area of dust around it, to a depth of 5 nodes,
changing it to moonrealm soil. You can grow any farming mod crop in the soil.
A depth of 2 soil nodes with moonrealm air above is needed for a moonrealm sapling to grow.
Hydroponic liquid will saturate the 5x5x5 node volume of dust around it,
changing it to moonrealm soil. For growth a moonrealm sapling requires a
1 node depth of moonrealm soil and 5x5x5 nodes of moonrealm air around it.
