There’s a particular user here Charles Farley or something with a Barney the dinosaur avatar that claims he’s isolated sativa characteristics from the original NL release, after breeding it for several filial generations. You can look up the old threads if you want to do a deep dive, but the conversation got a bit argumentative at times. He’s got a website talking about it too, and has named his strain something different but similarly constellation-based in name.
The plant you posted definitely represents with sativa characteristics, but who’s to say what the actual lineage is. It’s possible to get freak representations from parental lines sometimes, but if you’re solely after indicas, this doesn’t look very promising. You’d have to ask the person you got the seed from for more details.
