I got started working on hydroponics because I didn't like digging and weeding. Besides that I'm a techie and we like to make measurements, build things, and just figure out how things work. It's a lot of fun. Hydroponics was a natural. So when I started fooling around with it now about thirteen years ago it was a never stopping kick, each different system, each different plant or instrument was a different adventure.
Now I think all work is fundamentally spiritual. We are creative beings and we imitate our creator as Tolkien pointed out with our ability to subcreate. We can't create from nothing as God can, but we can create marvelous things by manipulating the elements of God's creation that He has made available to us.
But there's another dimension beyond our own subcreation and that is the reflection on close inspection of God's own creation. St. Paul says in Romans 1:20 "For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; ..."
As one tends one's hydroponics system the wonder of plant growth is a constant revelation. I encountered a picture on the internet of dew drops on leaves of grass and I've added a picture of just one drop of dew here. The wonder is everywhere and it fills up one's spirit.
