The success of the recipe itself can be very hit and miss and is very much dependent upon choosing exactly the right location and weather conditions; moss thrives in the damp and can most often be found growing near to a leaky drainpipe or rain-soaked wall. If you have difficulty finding the right climate in which to grow your moss, grow it indoors (where it can be frequently spray-misted with water) and transplant it outdoors as soon as it has begun to grow. This is what I have done in the example shown in this instructable.
*Several clumps of moss
*1 pot of natural yoghurt or 12oz buttermilk (experiment to see which works best)
*1/2 teaspoon of sugar
*Plastic pot (with a lid)
nb If growing your moss inside you will also need a seed tray containing compost
