You've got a week or 2 to go.
And 3 days of "darkness" is a frivolous activity that really does nothing for your plants.
Might as well water them with ice water too, get the plant thinking the end of season is approaching and it will make the trichomes burst in the last few days, LOL
Not yet. Have another look at it in a couple of weeks.
Also, this idea of putting them in the dark for a period of time before the chop, is complete nonsense. It is more likely to have a negative effect than a positive one.
I don’t see any swell? If that were me. I’d run an extra week on Top of the 2 left. Try to pull some weight. But that’s just my opinion. Idk how your situation is on herb.
