G.S.C. Root Ball monitoring

a growmie friend of mine had a plant turning hermaphrodite and a good chunk of his plants started giving seeds toward the end of the flowering stage. Harvest was pretty decent; however, several buds had seeds in them. Of all the seeds collected after harvest, he gave me one to play with and I decided to cut a plastic pot in half, add a sheet of glass and start monitoring the root ball development :-) I'm using black cardboard onto the glass to screen direct light hitting roots, I remove it briefly to take photos. 22/05/2022 seed in water for 48hours 24/05/2022 seed with taproot into medium 25/05/2022 already sprouting out! 29/05/2022 GSC at 3cm and roots are quite visible...
