not sure what DWC is but i use a drip system. so probably similar results... dunno. i cut mine when i feel they are finished, some plants may take a few more days so i leave the system running. i trim the buds right away, never liked waiting for them to dry and trim. but to each their own. after trimming i will let dry for 10days or so in the dark. waiting for the green colors to turn almost grey. thats when the chlorophyll has been broken down. then when the buds are nice n crispy on the outside i cut off the stems and cure them in a jar for 3 to 7 more days. this allows the moisture from the center of the buds and the stem to disperse into the drier crispier parts of the buds. this is just how i do it, takes a bit longer but seem to have good results. hope that helps a bit.
