(Bert) the bigger of the two had came out of the soil first, and had the longest root after germination. (Ernie) the second and smallest one didn't take much longer, and basically caught up to Bert. After transplant Ernie lost most of its roots, and didn't grow for 2 weeks while Bert had exponential growth. Ernie still hasn't fully caught up to Bert horizontally in flower, but vertically are very similar.
@Smokwiri, @Ferenc, thanks guys you're too kind, I'm quite new to growing so they're not that great, but it's nice to see all the support. good luck with your 2021 harvests. :)
