Hydroponics Tray

The hydroponics tray is the simplest indoor bed. It has two slots: one for the plant or seed and one for fertiliser. It needs no power and has no logic values.

The tray gets its water through its two liquid pipe connections. In the game it is a pipe piece holding 100 litres: several trays in a row form one shared network with the pipes, and the water spreads through it. Like any liquid pipe it holds at most 6,079.5 kPa.

According to the game data a normal plant drinks 0.00006 mol of water per tick. At two ticks per second that is 0.432 mol per hour, just under 8 mL. One litre of water (about 55.6 mol) therefore lasts ten trays almost 13 hours. Rice drinks twice as much.

The plant takes light, heat and air from the room. The tray has no light of its own, so you need a Grow Light or sunlight through a window. Everything else plants need is covered in Farming: light, water, temperature and air for plants.

If you want to read growth and ripeness with IC10, use the Hydroponics Device variant with a data port. Both are built from the same kit, which the hydraulic pipe bender makes from 10 iron. A wrench is enough to take it down.
