The normal
home Hydroponics system is usually made up of a few basic things: a
growing tray, light (natural or artificial), a reservoir, a water
controlled pump for watering (or some type of watering equipment), and
some form of air pump to give oxygen to the nutrients.

It's nice that's it can be done, but use electricity to do what can be
done without electricity? Seems like a step backward to me. Wasteful, too.

It sounds like a good method for growing veggies on a space station
somewhere.
