Ouch,the place i've collected the rock is 80km for from my home
Sorry but i dont have the pic Arowanaman.
And i have no ideas what rock is it.
But the people here call it "Bee nest rock"
Its usually found in red basalt area,it said to be contains much nutrient in it and very suited to grow rambutan and durian.
Hope it can helps.
Ahh,this is my plants plan.
