Frank. I did the same last year with chillies, peppers and aubergines...sat them on gravel in bottomless pots.
Aldi are selling grow bag trays for £4.99 and Wilkinson have the large square trays, for about the same price, both ideal for sitting pots in and using as gravel trays. You find you water less, the compost only takes up what water it needs and less compost is used. You can also go away for a long weekend and not worry about the pots drying out.
I sit the gravel on capillary matting.
