I potted up some winter lettuce and cabbage plants in three inch pots four days ago. They are coming on nicely and they are all erect and healthy looking. I put them in an unheated conservatory (no greenhouse) today I noticed a grey coloured fungus on the top of the potting mix. I put them out in the air in a sunny spot (nice Sun today). What am I doing wrong should I leave a window open? I gave them a good watering to start but none since as they feel moist enough?
