By the way, Bear you might be right. Most of seedlings look different. One has long narrow leaves and two of em have short fat and are compact. I got 'em from BC Bud. They have a real bad rating. At least I got some. And I've read you also never really know what you've got unless you've bred 'em. Makes sense. I'm gonn pick-up some of that superthrive tomorrow too. Thanks.
