We never copy values between breeders. Souvenir Seed Company's Soureen #18 is not another breeder's Soureen #18.

Lab data

Have a lab report for Soureen #18?

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.
