Too hot also refers to the fact many of the bagged soil companies package their products while it is still composting and therefore is really hot (meaning temperature). This too often creates the "hot" youre speaking of. If you pick up a bag of soil thats indoors and you open it and stick your hand down to the middle and can feel it being very warm/hot then your soil was not properly composted before it was packaged, unless of course that bag has been sitting in the hot sun for days.
