I use Two Wests water matting.
A possibility might be sieved ash, David - light, inert and relatively cheap when available?
The closest in size would be Sophisticat Pink clay cat litter, but it is not quite so hard from my memory of Hortag.
Mmmm ash, interesting! Rare as rocking horse manure these days I suppose. Well at least it is in Devon and Yorkshire where we now have gas and electricity and don't need to cook outdoors. Don't worry Cliff Lancashire will catch up one of these days
Aye up lad, thou knows I mean 'industrial' or furnace ash, which southerners and t'others still use in abundance.
I think that might keep my bulbs too wet Martin.
