My NL5 is unreleased genetics from 1989 and only regular seeds. It did not make it to the Sensi catalog as Neville was incarcerated in Australia, so it can't be called Sensi.
I'm about to make f4s of these with a mother that is all nasty garbage funk. I don't get any menthol off her at all. She smells like a pile of rotting fruit garbage. I always say she smells like an orchard that has a dead squirrel buried under the rotted fruit that has fallen from the tree.
You should see a short finish, but a long veg on NL5. She's not a vigorous grower, and basically needs to be the size you want her to be at harvest when you flip her, as growth when flipped is pretty minimal, I usually see less than a foot of extra growth when I flip new nl5 starts. That is why she's perfect for stealth and short spaces. You'll really lose on yield if you do less than a 60 day veg. And don't top her too many times, one topping around 30 days, then a pinch of the top shoots about 45 days, and that should really be it.
If Sensi is using a mother that is sativa leaning you might get more vigorous growth in veg on some of the shoots and a bit longer flower, but I haven't found a pheno in mine yet that goes beyond 52 days. I do know one thing, watch those fems like a hawk. I've read lots and lots of herm reports on these, keep your eyes open.
