We never copy values between breeders. TGA Subcool Seeds's Chernobyl S1 is not another breeder's Chernobyl S1.
Lab data
No lab report here yet
Have a lab report for Chernobyl S1?
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
2 breeders sell a Chernobyl S1
A name is not a genetic identity. Each row is what that breeder published, on their own page.

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