Brown pistil question

I always base my harvest timing on pistil colour/condition and not trichome "amber" percentage as this has problems. Not all plants get amber trichomes and others can have 70%+ amber after only 4-5 weeks of flowering, it all depends on genetics. Pistil colour is a direct relationship to plant maturity and it is plant maturity that determines trichome composition, not trichome colour. 50% brown pistils is about "child" maturity with limited THC levels. 75% brown pistils is about "teenage" maturity, with rising THC levels but well below peak potential. 100% brown pistils is "old age" maturity with declining THC levels and well beyond peak health. Personally, I start a flush when there are about 95% brown pistils and harvest one or two weeks later at peak maturity when there are about 98-99% brown pistils and just a few white pistils left right at the ends of the buds. This will give you buds with peak THC levels and moderate CBD levels and makes for a well balanced effect. It will also put you in/co-incide with the mythical "10-30% amber trichome zone" without having to look too closely at your buds. Harvesting a bit earlier at around 95% brown pistils will give you a more clear THC influenced "head high" and harvesting a bit later at around 100% brown pistils will give you a more sedative body stone effect due to THC degrading into CBD after peak maturity. Let your preferred style of effect influence your own harvest timing! My recommendations are based on my own experiments conducted over the last 35+ years of cultivation. Hope this helps, Organoman.

When the pistils are about 50% brown is the signal to me that I need to start watching the color of the trichomes.. To be honest, I don't know what percentage of pistils are brown when I finally harvest because that's not the indicator - it's the trichomes! They go from clear to milky to amber and I like harvesting when the pistils are about 10-20% amber... Good luck!

I like 75%, make sure you count the pistols accurately to ensure an exact 75% ratio! I hope none are " Johnny Rotten " 👍

I might be mistaken but although it can be a sign of maturity, I think the pistils are only a genetic question .. you should guide yourself from the trichomes head colors ..
