now that you mentioned about hydrophonics starting from babylon and aztecs...

i hope that the present generation will not perish like the way those old civilization did.

does hydrophonics anything to do with that? ok, maybe the babylonians have a different story... but the aztecs, that i'm not sure? or maybe they were penalized to extinctions by acts of defying the natural flow of nature... who knows?!

as far as i know, all the nutrients that hydrophonics are using are all manmade chemicals produced from a chemical processing plants... are these processes sterile as well? howabout the handling and trasport of these chemicals? how about the water that we use, are these sterile as well? how about all the planting mediums and trays. is was deemed toxic to use styrofoams nowadays, but are we aware when we use it as planting containers.
even plastics containers are toxic at some instances, what more if it is continuously exposed to chemical+water solutions.

and there is more to that... i guess :(

as it goes, we are all simply looking inside the box, but the view from outside is way more staggering to be comprehended...

yes, somebody here said that too much cleanliness is not good for the health as it keep human farther away from developing immunity to some sickness.

have you ever wondered why people living at garbage dumpsites are more resistant to some common sickness?

"some people believed" that organic is healthy. but the term organic itself is still vague. for one thing, composting is also termed organic. and there are many ways to do composting. even dead animals carcasses can be composted ... and still called organic per se. i think the best way to produce organic compost is by using the best composter around.... WORMS!!

i had experimented on hydrophonics before, with some good results. but i still need to come up with answers to many BIG questions before taking its seriously in the future.

NOW I AM CLUELESS :P
