Also has a lot to do with the grower. I have ruined plenty by not knowing how strong to feed or too much/too little light. Nutrient lockout is another one.plently of 'low' potency cultivars that rip your head off when treated right man... for instance the real sour like 18%,real cheese 16-18%, i was just quoting riot with the loompa % thats all, we all know these thc levels mean shit (within reason) its all about the entourage effect...every one says the loompa is killer regardless of the testing,sure you'll make her shine @flower~power
