Ok. so you got 1.3kg for £5. Its all the same anyway, Do you have a homebargains shop near you. They are selling it off at £1.79 for 3kg.Anyfoot, my coir is the reptile bricks they sell at petsathome (they only have one type) they were on offer two for £5 when I bought them.
Ladyengineer, I'd really recommend it, it holds moisture really well and it smells nice too. Also I've read that this shouldn't go mouldy especially if you mist it/don't leave it to sit like lots of plain soils do.
