d you know what strain (breed) it is? there are some that are "low odor" breeds.. and also- depends on what/how you feed them.
You say it is 12 weeks old? how long did you veg, and how long has it been in flower?
When did you start 12/12???
You may not have let it mature before flowering, which means it won't produce as many of the turpines and resins as a mature plant would... still good smoke-- but could be better...
if there are no crystals on the plant-- she's not nearly ready... give her time.. and give us some more info so we can help ya better!
