Rasing the temperature to about 78-80 usually speeds up the fruiting process. BUT, if you are going to raise the temperature, Do it slowly. if you raise temps very quickly during the pinning process you will get alot of abhorts. so raise it slowly over the course of a day or so. Im not sure about the worm castings. If they arent nutritious to the mushroooms, they arent hurting the casing layer any.
