% in a timescale is dependent on strain, but into the 4th week around 0-10% should turn. 6th week 40-60%. 7th week should see most hairs turned. So over the next 2-3 weeks IMO. If your strain has a long flower period then I'd add a week-week+1/2 to those figures. There is an explosive growth stage which occurs during the bloom stage and a lot of changes will occur around that high activity period.

Red Hairs hi there peeps:p on two of my plants i have spotted literally just one or two red hairs amongst the billions of white ones, which means its all comin together now.. a couple of questions, this is the first time ive acually made it this far with plants so i dont want to mess it up. ive read all about the hairs changing, trichomes clouding, harvesting at certain ammounts to get different results... what i understand is that if all the hairs are red, then the crops past its best, im Rating: 5
