I heard the "beaster" cut that all those canadians used to grow in the 90's was regularly cut @40 days.
That being said that herb was not too good (being nice)
I forget the actual name of the strain tho..
I knew it at one point..
beasters. now there's a word that strikes home. Maybe a newer aged description? Yeah, it wasn't great. "dro", aka hydro taken early, dried in 2 days and bagged. no terps. often hay.
Found a very resinous cut (not "beasters) that finishes with amber in 56 days, I thought that was impressive. at 7 weeks its at 50-60% cloudy. The only cut i've ever had that shows 10-20% amber at 56. it hits true flower around day 7 rather than 14-21.
