I was always told not to use builders sand as it can contain lime and
kill some plants. I've not been able to find any sharp horticultural
sand here in France

Builders sand ('soft') and sharp sand from a builders merchant are
different sands.

Probably the only difference between sharp sand from a builders merchant
and a horticultural grit is the price. A builders merchant will supply a
cubic metre of sharp sand for the same price a gardening centre will
supply a 1Kg bag of 'specialised' grit
