It's from an unknown strand. I was thinking it's a heavy sativa due to the size and shape of the leaves Oh yeah, it's only 3 weeks old!!
Sativa leaves are very thin and spindly. Those are nice thick leaves. Is that plant short and squat? It looks like it is. I am going with an Indica or Indica dominant. P.S. It is "Strain" not "Strand". Just so you know.
it's definately indica dominant...but no one will be able to tell you what strain it is. Theres so many strains out there, not to mention the genetics can vary greatly between seeds...so no one will be able to tell you what strain.
