My flowering plant durrr naaarr

hey guys, haven't posted in a while...whats uppp

this is whats up. I have a hydro setup my own setup it works pretty good. my plant its female, grown from a clone, about 36 inches in height, and flowering. I am pretty sure that it has been 5-6 weeks now. The buds are getting along nicely lots of white crystals on the small leaves etc.

My question is how much longer should i let her flower for, 4 weeks? also she has lots of long white hairs sticking from the buds, is this evidence that they are going to swell?

thanks lads

as to when to harvest depends on strain growing and type of high you want. generally you can figure on;
indicas 8-10 weeks
sativas 10-14 weeks
i always add a good 2 weeks to the flowering time advertised by the breeder.
