Went to Lowes in Fenton MO yesterday and they had vermiculite on the shelf. I had been looking for some with no luck, so if you are looking, try Lowes. I mixed and sterilized 6 liters of 1:1:1 today and plan to pot up some babies this week. Haven't seen any more of those fungus gnats for about a week now and hope they are gone for good. I actually did not know what they were until I posted the pic on this site and you enlightened me. Thanks.
