Yeah and then he will leave them with no leaf for a few days,a week maybe to fully ripen them quickly by exposing more of the bud to the sun and to make his exit quicker on the next visit.
Personally i would never ever go back to that site,it has been compromised.
Its an old trick to wait and pounce on outdoor growers returning to their sites but only after they have cut it all down,as well as to incriminate them fully it also saves the police a job that they hate,having to cut it all down.
You are right though in that in an ideal world those could have had another 2 weeks,but most cannabis plants of that manner especially from outdoor grows have many windows for harvest ripeness and can be taken even from 6 weeks as each new set of trics and calyxs ripen.
Leaving them longer and longer just increases your final yield.
In theory you could keep a plant flowering a long time if you could get it to not hermie or go mouldy.
I think that your original question was a valid one and that this has all been blown out of the water and is unnecessary,i cant be assed to read 30 pages though to see what has gone one
