I have popped over 1000 seeds and the Chem Cookies (chem4x cookie) and White Cookies (the white x gsc) are up with the very best of them. This is my keeper pheno #3 out of 40 seeds it tested at 29% total cannabinoids. One pheno tested at 29% thc but I like the smell of the 3 best. A very very strong overpowering chemmy smell with sweet dough undertones. Very potent meds. She finished at 63 days which is way shorter than a traditional Chemdog #4. With this strain I am very confident I can get around 5 lbs per 4x8 tray under 2k watts of hps.
