A motherlode is the vein everything else branches off. The Lab reads one specimen; this reads the whole cave at once: who else has what you are looking at, what it actually is, what you are waiting on, and how far you have been.
Thirty independent growers share this cave, and some of them carry the same genetics. A seam is a strain that surfaces in more than one place. No single storefront can show you this, because no single storefront has anyone to compare itself to.
Every listing here is sold for microscopy and taxonomy use, so taxonomy is the honest way to arrange it. This is the cave sorted by genus and species instead of by whatever heading each shop happened to invent. Read from the listing text, so it is a reading of the catalogue rather than a vendor declaration.
A watch is on a strain, not a listing, so it is listening to every vendor in the cave at once. Anything you are waiting on is here, and it is checked each time you come back.
Strains, vendors and countries you have collected from, and the ground still uncovered. Read from your own order history and nothing else.
