Root porn please

So I see all these awesome logs on here with plant and flower pics.
Can someone post their root pics throughout the grow to see how they change?
I'm new and wonder how people change their water level in DWC to promote root growth throughout the grow process.
As soon as I get 50 posts, I'll start my root porn log :)

lots of posts on here with root pics for various purposes, also not sure if you need 50 posts for pics, give it a try.
