GSC is a consistent strain, or at least the auto version has been for me.
When I used a blurple LED, it would finish at 63-65 days. With better lighting (HPS and LED), I usually go 75-90 days from seed before harvesting.
You should have a very nice aroma coming from the plants. Carbon...
I had a harvest drying when I had my portable A/C go out for 13 hours while I was away at work. By the time I got home, my room was 90 F. It had to of been out for awhile, because half the buds in the dry tent were crispy and it was only DAY 3 of the dry.
I'm not going to lie, that shit still...
Day 23 (x2 Roc-It Fuel, x2 The Fringe V4)
48 hours dry (x3 Magic Cookies)
Dry tent is smelling delicious with temps hovering between 70-75 and RH anywhere from 55-63%. Lots of rain around here the past week, so RH has not been an issue for a bit. I am seeing what appears to be some well formed...
Day 84 (x3 Magic Cookies)
Day 21 (x2 Roc-It Fuel, x2 The Fringe V4)
Harvested all 3 girls today. They are drying in a separate tent with conditions steady at 72 F and 53-55% RH.
Don't like the way these girls leaves finished. At the first sight of the yellowing, I re-introduced the grow nutrient. Not sure if that helped or just made issues worse. Tomorrow is 80 days and they are in the harvest window (early). All three have very solid nugs, with the smaller (topped by...
Probably a good thing they were given to you, considering the previous person didn't know if they were photo/auto or even how old they were.
Good luck, hopefully you see it through to harvest.
I agree with everyone else, not an autoflower.
In less than a week, the leaves went from super dark green to yellowing. These girls really sucked up that Nitrogen for their final swell. The last two waters I have actually fed 1tsp of Grow Big. I'd still like to go another 10 days on these girls, so hopefully that will slow the yellow some...
