i flush the pot at the 1st day of the last week using 3 times the volume of water to the volume of the pot. that is the last watering it gets before cutting , when the plant is in total darkness its starts to produce more thc to protect the flowers in a vain attempt to get pollenated before its too late . i wouldn't say it makes the flower bud any more but it helps the buds fill out and firm up. which means when it drys, the bud wouldn't be light and airy. the advise came from Soma of Soma seeds , i have a friend who is a friend of his , that where my nydc seeds are coming from in the next few weeks . i am going to the cannabis cup in november for a couple of days and i hope to meet the great man himself.
