Day 13 - Still going! Twin 2 seems to be in the lead. They'll probably take longer to get to transplant size, I'd say more like day 20 instead of my usual week 2 transplant.
@greengoldgrower, wow it happened to you too! Yeah I separated mine, they were already beginning to wrap around each other. I’d suggest digging them out as carefully as you can and then quickly replanting them in separate pots. I’ve read that the roots will get tangled and the plants can die if they’re too close like that. Mine seem to have survived the transplant. Good luck with your grow!
