True true. I cut btwn day 65-70 and the head/body high was potent and long lasting over 4hrs for some daily tokers i shared with and about 6hrs for me.

I feel you guys, but I'm watching those glands
and the trichome heads could be fatter! I swear! They're developing nice though
Just a few more days I plan on letting it go til like 95ish before I cut it.
I'm not going to let it rot on the stem
I'll post photos tomorrow and you guys tell me what you think.

Hey Verde,
Don't listen to the guys that say chop early. There's too much speculative disinformation on these forums that isn't based on reason or science. Proper harvest timing is key. Check out kindreviews (dot) com to see how critical it is. They basically review and grade the medical strains available from dispensaries in Colorado. If you read through a lot of their reviews you will see that the top rated strains (they give each one a grade from A to C) usually have a decent proportion of amber trichomes (the reviewers are usually looking for 10-15% ambers to indicate a properly timed harvest). All their samples are also measured by a laboratory for a complete cannabinoid profile.
Additional harvest timing information comes from this scientific paper titled "Assessment of Cannabinoids Content in Micropropagated Plants of Cannabis sativa and Their Comparison with Conventionally Propagated Plants and Mother Plant during Developmental Stages of Growth". It is by a group at the University of Mississipi, the only government approved cannabis research facility in the US. I have graphed some of their results which are attached.
The basic summary of their findings is that "Δ9-THC increased with plant growth, reached the highest level. . . . . .followed by a plateau for about two weeks (optimum harvest time for highest THC content) before the plants started showing a decline in Δ9-THC content which is considered the onset of senescence of the plants."
So the way that I understand it is that THC will peak at a certain level, and then you have basically a 2-week harvest window. After that THC does start to degrade, but even then it is pretty slow to degrade losing only a couple percentage points over the course of the next couple of weeks. So it doesn't degrade as fast as people seem to think. The strain used in the above study was a Mexican strain and obviously there will be differences between strains as far as days to peak-potency but I think the general trend should hold true across most strains.
Just my 2 pennies, the info is there, take it for what its worth. Just trying to help by providing some facts based on science and actual measurements.

Hey bud! Thanks for contributing to the conversation!
Yes, this is pretty much the information I've been following. From what I've learned, trichomes grow skinny and long and clear, then develop some heads, eventually increase in size.... then turn milky white over time.... milky white trichomes with very large glandular heads means the plant and trichome is peaking in THC.
Once it begins to turn amber, it means the compounds inside the trichomes are degrading into CBD/CBN (other useful, though not as potent cannabinoids).
Therefore, according to that information, you should cut your plant down with 10-15% amber trichomes like you said, as this indicates that the plant HAS peaked in psychoactive compounds, and the plant is beginning to degrade those STRONG compounds into not-so-strong compounds.
The trouble is that the trichomes don't seem to be changing to amber, though we are 90 days in.
So again, I'm probably going to let them run up to day 95 or so before I chop... IF nothing goes amber by then!

Great news... checking my microscope.. seeing like 3% amber.... the cloudy tirchomes have some rather LARGE heads on them.... 5-7 days seems like it might actually be the right time.
The colas keep on puffing out
looking better and smelling better each day.... I....musst......waiiiiit!

Day 93 flower.... what do you think guys does this look like it's about finished quality?? 
snipped a small nugget, one of the poorer popcorn nugs.. want to let the good nugs go the last 2 days.
here is the photo FRESH off the stem after I trimmed it up a bit... so it should shrink down quite a bit and look more frosty...
I just watered the hybrid for the last time.. :'( awhhhh.... kind of sad. It's so pretty.
Let me tell you guys though! The sativa pheno is OUT OF THIS WORLD! It's insane how much more covered it is... looks like something out of high times.... still has a lot of white pistils though... the trichomes on the sativa are maturing a little easier I think... looking very white... but the pistils are still not receding so much.
Come monday, the Sativa pheno will have 2x as much space to stretch out to finish... Should be nice for it. NO idea how much longer the sativa pheno has but it's def. at least 2 weeks I think. Works out for me I have some things going on after I finish drying my shit... So I won't be paying much attention to the sativa besides watering with plain water every 4-5 days... checking on it every few days.. & burping my hybrid pheno 4-5 times a day in some mason jars..

Fuck this strains stems ! follow one from the bottom to the top!
so.... what do you guys think?
The hybrid is looking real good. Really ripened out in the last week, like one last fattening.

Just curious, Verde, how tall are these plants? And how deep are those buckets? I keep thinking about this strain myself, but I want to be sure I have the space. Awesome grow, by the way. Can't wait to see the harvest report. Your journal convinced a friend of mine to go with a 250. Well done.

Thanks dude
Good to hear i influenced a fellow horticulturalist... i couldn't find much info or REAL continuously updated journals on a 250w tent setup so I had to make one..
plus I'd forget days and loose pictures... better to have them on here..the pots / buckets are 3.5 gal.... the strain takes forever unless you want a 90+ day strain for it to become realllly finished... i'll tell you in a couple months after a 6 week cure if it's worth the grow
as far as the height, if you look on the pole on the right, it's marked..... about the hood level is 3 ft.....
of course this measurement is from the soil up.

Nice! Good job verde! Congrats on the harvest. Bet that sativa is going to love the extra breathing room! Look forward to the smoke report....in 6 weeks ha
