The hairs turn amber, that has nothing to do with Tric's... Tric's can only be seen with a magnifier... When ALL of your white hairs recede into the bud you will be close
Go get yourself a mag loop to check
your trics!
Trics Notes that most do not know:
Plant will make clear trics until the day you harvest
Plants Trics [after harvest] will change color as plant ripens, I check for frosty buds, when I smoke the first of a plant, after it is dried and cured
Degraded Trics will appear Amber/Tea colored = Less THC
Not a couch lock high
[Thats an old stoners tale]
Harvest Plant when you see no White hairs [they will recede into calyxes]
Harvest plant when you have 5-10% clear Trics
your plant will never have all milky/cloudy trics [5-10% clear--80-90% cloudy/milky--and yes, 5-10% Amber/Tea colored
Good Luck, especially with all the advice you will get here at RIU !
