Need Help On When To Harvest

[medmanmike]

I have a plant of what I believe to be Green Crack. I obtained some seeds off of Craigs list, so who knows.

 

My understanding is there are a couple of different phenos around. One being more Sativa like, the other Indica. This is the first time I've grown it, so I didn't know what to expect. I topped the plant once, LST'ed and pruned it for four main colas. The colas have very few sides branches. the few branches there are run tight to the main branch.

 

I vegged her for three weeks under CFL . Switched to 12/12 with brand new GR8 LEDs. Most seed companies carrying GC says its 55 days, though I've seen reports of it going 65.

 

Today is day 71. She stopped growing around 38" from the pot rim. She continues to explode new white pistils, though the pace has slowed. Trichs are predominately clear, with a quarter or less milky and a few (very few) are noticeably starting to turn 'amber'. I'm looking basically for a 40/40/20 split of clear/milky/Amber.

 

In the last week, she's displayed an occasional nanner in the upper most buds. None lower on the plant.

 

I KNOW that she'll eventually finish, but 70+ days is making me nervous. Any thoughts, advice, similar experiences would be appreciated. Thx.

She definitely has a ways to go still. Looking good though!

Gotta wait for those pistils to turn brown your at least 2-3 weeks out from what I see in the picture best way to tell is to get a eye loop and watch for the trichs to go milky or amber .

Yup, that's what I do.

iv got one plant that has been in the flower room for every bit of 78 days and its just exploding with white hair all over.

I thought its only the ripeness/degradation of the trichome contents for  considering a finish/harvest time?

some hairs are red, some white, some purple, some red and some stay white through finish, not making a very good "pop up notification" imo.

curious what genetics are taking this long to finish in your garden ?

i was told when i get the clones awhile ago that some were larry og an some cindy 99...both turned out to be same plant so unsure i have been growing it for 8 months or so none took this long but these 3 are

Here's an update on my "Green Crack" plant. I harvested her on day 78. Got 56.83 g dried. Here's a couple of pics. I'm a little disappointed on the yield, but the early smoke is nice. ????

There are some sativa dominants that can go 90 + days in flower.
