We never copy values between breeders. Positronics's Grapefruit is not another breeder's Grapefruit.

Lab data

No lab report here yet

Have a lab report for Grapefruit?

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.

Where these disagree, both are quoted correctly — the breeders disagree, not the records. Every figure links to the page it was read from.
