Polystyrene (Pencombe HR7)

I have lots of polystyrene from packaging if anyone can make use of any of it before it goes to tge tip on Tuesday? I believe some people use it at thebottom of plant pots to save using so much soil and for drainage but have never tried this myself. Could be used as a stand if you need to hold somwthing whilst paint dries etc (if its something you can poke into the foam eg screw off handle). Collection from Pencombe area. Booked into tip on Tuesday so would need to be collected by Monday, take as little or as much as you want
