We never copy values between breeders. Medicann Seeds's Cali Jack is not another breeder's Cali Jack.

Have a lab report for Cali Jack?
Breeders publish claims; a COA is a measurement. We cannot read them off anybody’s website — of 160 products checked, none carried one — so the only way they get here is if somebody sends one.
Same name

A name is not a genetic identity. Each row is what that breeder published, on their own page.
