Hmm, I was just reading up on flavor enhancers today too. The only thing I've used is sugar daddy from technaflora. Not sure if it helped or not because it was a long time ago and since stopped using additives.. But I figure there's new products out by now and was wondering the same thing. The top terp enhancers (from what I've read people have success with) are sugar peak grand finale, bud factor X and terpinator. But I've also read some people didn't like terpinator , but others think it's great. I think I may try one this grow and see what happens. I just want the natural flavor and smells of the plant genetics to be more pronounced and do not want the flavor of the additive in my buds. That's why I've stayed away from such additives for so long, I don't want my kush and lavenders tasting and smelling the same like the additive.
