Compost-friendly plant pots

I seem to be having a plant frenzy this morning - anything to pretend it's not pitch black outdoors and the middle of winter - so I'm on the hunt for new pots. Lo and behold, I found these biodegradable Vi-Pots on Green Gardener's site. Apparently they're made from materials 'such as' coconut husks and grain husks; the important bit is that once you're finished with one, you just crush it and chuck it in the composter. Crushing the Vi-Pots breaks the protective glaze that, unbroken, gives each one a five year life. 30 small pots will set you back a tenner, 10 of the large are going for £13.50. You'll have to wait 'til the new year for delivery.
