The breeder at ACE has even recommended 10/14 for some of their sativa strains to get them to finish. At 12/12 they'll just keep flowering. I pulled an Oldtimers Haze at 20 weeks that was still shooting new pistils. Every time I thought it was done new clusters would shoot out. It was crazy. I probably should have let it go another 4 weeks or so but it was taking up half my tent and I had a backlog waiting to get into the flower tent so it had to go. Turned out to be some damn fine sativa smoke. I'm glad I grew it but 20 weeks was a chore when I'm just flowering in a 4 x 4 tent. The next sativa run of ACE Ethiopian I flipped those suckers after a couple weeks straight into 10/14. It seemed to really help and they finished in about 13 weeks. Great smoke as well.
I have the Kumaoni but am afraid to grow it indoors as they can get quite large. I don't know if my 4 x 4 tent is up to the challenge. There will have to be some serious training and at most only a couple week veg before going into the flower tent. But I do need to grow it for seed reproduction so I might just plant all the seeds and flower after a couple weeks.
The Rasoli sounds interesting. My next sativa run is going to be Malawi. I'm getting ready to toss some F5's of my Durbistan cross I've been working on in the flower tent. But The Malawi is up next so I'll get some geminated in a couple weeks. It's supposed to be potent. I've never grown it so we'll find out what we can achieve.
Good luck with whatever you decide to grow next.
