You should harvest when the trichomes are mostly white and very few amber. You'll probably need a microscope for that. Heres a chart

Earthy Dank Reviewed by Earthy Dank on . When to harvest - Brown pistles vs. amber trichomes? Hi all Just a quickie.. I checked my sweetheart this morning, and about 1/3 to a 1/2 of the hairs have gone brown, buit my trichomes are still quite clear. I have read that you should harvest when 2/3 of the hairs have gone brown / when the trichomes are amber. If I leave it until all the pitsles 'die off' in order to get more cloudy / amber trichomes, am I doing the wrong thing, as I know that potency can deteriorate quickly? Rating: 5
