no one has answered you so i'll take a stab. take into consideration i'm very new!! no, i wouldn't unless i wanted to be nice to the girls before i chopped them... seriously, unless your area is really dry and you want them to have extra moisture in them, i would think watering them right before you chop would just add time to drying them. hopefully soon you'll get an experienced grower to answer your question. got any pics? would love to see them! either way, though, good luck with your harvest.
I wouldn't Im pulling my Critical Jack Auto on Monday and I havent watered since tuesday. This is my first grow so I have no experience with this method
