I don't pay extra for the tracking of the seeds. Speculation here, but I believe it goes through an Xray device. I once bought 15 seeds, 3 various strains from GYO w/tracking and none of them germinated. They did send me replacements w/o tracking and most of them germinated. Now I buy from Nirvana w/o tracking, they come discreet, no extra charge within 14 days and the seeds sprout.
