Disease? I'm not involving the fish in this, just house plants. I 
was thinking of it being a high-powered forcing nursery - 
"cuttings to plants in seventeen hours" sort of thing.
Perhaps you mean plant fungii, blights and such?

You're right. This is the traditional low-maintenance route. I 
will treat myself to some cactii today.
With all the hydroponic gardening going on, I wonder why large-

must know something. maybe it *is* the rapid spread of disease if 
once it gets into the system.
