CG>SP>  Good way to spread disease, Christopher. An ounce or two of water
CG>Disease? I'm not involving the fish in this, just house plants. I

CG>"cuttings to plants in seventeen hours" sort of thing.
CG>Perhaps you mean plant fungii, blights and such?
  I sure do, Chris. Closed in quarters with a lot of moisture favour the
  spread of inimical plantlife forms. :-(
  Nurseries that root cuttings in under a week use a spray mist, light
  and heating system. The timed sprays wash beginning moulds off the
  surfaces and control them, the heat spurs rooting, and the constant
  moisture (in strong light!) allows roots to form w/o letting the
  leaves and stems dehydrate.
CG>SP>  every couple of weeks, some succulent/cacti type plants, and a small
CG>SP>  opening in the lid would be easier, cheaper, and less risky. :-)
CG>You're right. This is the traditional low-maintenance route. I
CG>will treat myself to some cactii today.
  There's a reason for certain traditions. :-)

  Ever hear of the Greenhouse experiment that the gov't of Nova Scotia
  picked up? They built $2 million worth of fully automatic greenhouses
  to raise cucumbers (a high-profit item) hydroponically. The man whose
  brain they picked had persuaded the gov't of Alberta to sink a few
  millions into a similar project, and it failed due to disease just as
  the crop was maturing. The same thing happened in N.S.  (I personally
  think mother nature was trying to tell them something.) Was it the
  Springer project? Not sure.
  The most successful hydroponic crops are greens and sprouts, but even
  here, intensive care (human care!) is needed. No robots need apply.
  :-) Tomatoes are another good one.
