There's not a lot as stated before maybe 10%.... That's weird what u your saying about never seeing any, but I'm by no means an expert in fact a true newbie. It's just everything I read says to wait till they start to amber. This is why I say the more I read the more I second guess everything lol. Thanx guys gonna chop her I think
Yeah I know that's the common thing when you read forums and tutorials, I just don't think trich color matters much myself. I base it more on time, meaning number of weeks of growth, and general appearance of the plant, if the buds have filled out completely or not. Generally when the buds are nice and dense and the leaves are starting to die and 70-75 days have passed since starting 12/12 it's time.
Potency actually varies very little from week 7 to 10. It may decline very slightly in the later weeks but it's like a fraction of a percent of THC. So you might as well just base it on trying to get as much bud density and weight rather than how trichs look. I seriously doubt if anyone who smokes 10 week herb would say "this weed was clearly grown too long. I reject this weed". No, they're going to smoke it and be happy and say "nice dense buds here, gotta get more of this shit". Your particular plant looks like mostly Sativa though, so it may take longer than 10 weeks to fill out. And yes, pistils should usually be almost all darkened. What's the strain anyway?
