Hi Folks,  I have been lurking, reading with much interest, the threads on 
substrate, snails and the rest.  I have been keeping plants for about five years.  I keep moving my fish room so I cannot report on real old setups but I have had some with good growth for over two and a half years.  I tend to use about 2 inches of coarse sand, with a little laterite in the bottom half inch and plenty of digging snails.  Works great here.  

Next tank I setup will probably have a very slow flow feed system as has been described in older digests.  Think I will probably try feeding in pulses (add micro trace elements, maybe some hydroponics nutrients) every
two or three days.  Thoughts?

BTW some of you might be interested in my filtration system - plants!
