My Critical + smells great, grows great, no hermie issues, no nute sensitivity, just beautiful and awesome, has a great yield, but it makes me cough my ass off...It's trim makes the best Ice Water Hash though...and it isn't made of coughs...
I have harvested early, and late. Flushed and not flushed...all to no avail...after a really really long cure it starts to lose a lot of it's coughs...but it takes a long time.
