LOL it can get confusing, so right away I upgraded to get all three seed trays, and when I store them, especially if they are in the same species and their seeds look alike, I try to separate them with another species. Each species tends to have at least the same BASIC shape ... of course I am kind of new at this, I'll probably discover some far out combos, but right now, cactus seeds look like cactus seeds basically, the kidney shape, ferns look like ferms, asteras look like asteras, etc.
