Im using GH technaflora... Like I said barney's says 55 days and this is day 56.... Only HEADS of the tricomes are clear while 80% of the tricomes are completely cloudy...80 20. the longer you wait to start flush more yield. they really fatten up at the last 2 or 3 weeks . that's why I started to only do a 7 day flush . all that hard work has to pay off even more. if this is a personal smoke you can afford it the longer the flush the better . commercial guys do a 5 to 7 days tops. also if your organic you might not have to flush at all. what are you using ?
