I'm growing a sweet potato in a jar in tap water. It is placed by a window that receives quite a bit of sunlight. The roots are growing well and leaves are beginning to grow too.
As you can see in the picture though, the roots are growing upwards and turning green. I have read that they may be turning green due to exposure to light. But I can't figure out why they are goring upwards.
I'd be happy to hear what others think. Thank you!
