We never copy values between breeders. Expert Seeds's Grand daddy Purple is not another breeder's Grand daddy Purple.

Lab data

Have a lab report for Grand daddy Purple?

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.
