Growing Tray

Growing Tray is an early-game machine for growing/harvesting plants.

This tray consumes 3 Water per harvest and doesn't require power.

Later in the game it can be replaced by Hydro Tray, which consumes 33% less liquid and can (optionally) be powered to increase the growing rate of plants.
 * Another improved tray is Community Garden (which can be fast even without power). However, you would need a town with tenants for it to be useful, and only one Community Garden can exist in each town.
