My main objectives in growing are smell, frost coverage, and then taste as I feel if you have those the good high is sure to follow. That's why I'm a little concerned with the wifis but will still give them a run just because I've seen some good reviews. As far as the hermies I wouldn't be worried as long as you don't stress them too much, granted I only popped 2 but they were overwatered early on followed by a lockout of some sort and only got 1 sack on Tahoe 2. None on Tahoe 1 which was less stressed than Tahoe 2. As long as you give them a decent -good life I think they will be fine.
If going by when I started 12/12 today is day 73 and will chop at day "77". But I did start flower 21 days from seed and its controversial but I've read they can't flower until a certain maturity no matter the light cycle plus I did stress them so taking those factors into account I'm guessing that's why. If going by first pistil today is 9 weeks exactly.
Good luck with Tahoes man sfv leaning is nice but look for the stretchy Tahoe leaning. Hopefull you'll find a pheno even closer to the Tahoe than I did.
