We never copy values between breeders. Heisenbeans Genetics's Chem 4 is not another breeder's Chem 4.

Lab data

No lab report here yet

Have a lab report for Chem 4?

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.
