Cheers Mark, the first image was already in the down loads file, so saved my back lugging for a another photo, as for the river pebble it is for holding to keep the fine soil in place to promote more root on the rock, as I m foliage watering a lot, if it goes to a show or photo they are removed and the dressy stuff goes on, a lot of guys like to use mesh...same result but...ask as many questions as you like its all good

...cheers
