The surface of the leaf looks a bit smooth. But one important sign of a marijuana plant is the serrated edges of the true leaves. Those do not have the saw tooth edge.Whatever it is it's growing pretty fast. I left the seed in a room temp cup of water for 24 hours then wet paper towel zip lock behind the laptop where hot air comes out. The seed popped open so I placed it in. 6 days later in the exact spot this is the result.
