How long till harvest

I'm with Organoman some strains have milky amber trichs at 4 to 5 week flower, therefore I recommend waiting till all those wonderful pistils are shriveled up and have gone from the color in the pic to a red rust color. Along with a magnifying loop or microscope you can keep a eye in those trichomes. When I'm growing a strain that has milky amber at week 5 flower I focus my attention to how large the glandular heads are and if they are swollen or buldging and if the stocks of the trichomes are starting to lean over due to the weight of the resin in the glandular trichome head. When the trichomes have started to swell and lean along with pistils turning red is when I know I can safely harvest at the correct time. Remember all strains mature differently and your environment,nutrients,lights soil,coco,hydro all have a impact on how your plants mature. Cheers!!!

Thanks growers!

About 3 weeks or once there are 95-98% brown pistils. This will give you peak THC levels and be in the "10-30% amber trichomes" zone without having to even look at the trichomes and guessing the percentage of amber. Remember too, not all strains get amber trichomes and some will have 70%+ amber after only 5 weeks of flowering, this is why I recommend judging by pistil colour rather than amber percentage, which has many genetic variables. Besides, pistil colour is a direct link to plant health and it is plant health that determines trichome cannabinoid composition, whereas trichome colour on its own does not. Hope this helps, Organoman.

The only true way to tell is by looking at the trichomes under a jewelers loupe or microscope( clear = low thc, cloudy = high thc, amber = thc degrading. Or use the old fashion method of when 90% of the white hairs have turned brown.

If you have a lens to see the coloring of the trichomes it's done😎 you can also find it on amazon .. so unfortunately you can't give a precise date
