Parsley, Snow Peas and Carrots

Yesterday I bought 3 punnets of seedlings. One of parsley, one of snow peas and one of carrots. I also bought a 'Mushroom Farm', which is a polystyrene box with two plastic bags inside. One is filled with mushroom spores in some sort of mixture. The other is labelled 'peat moss'. The instructions told me to spread out the spore mixture in the box, then cover it with the layer of peat moss, squirt with a mist of water and put it somewhere humid and dark. I did as advised and put it under the laundry sink. I now need to wait a few weeks...
