Ya its strange but the first year i used this lava rock i went to repot in spring and found it had turned into muck at the bottom of the pot. I dont think winter has anything to do with its makeup but when the water in and around the lava rock freezes it crushes and cracks it up....well thats what i think anyway. Could be just cheap quality as well. It was the first time i used lava rock in my mix....and the last because i found the recipe that works with me.
