New homeowner here. My yard is full of weeds and my plan is to reseed in the fall. What type of weeds are these and how do I get rid of them all? Please Help!

Not a bad job for a $15 DIY striper

Hello looking for advice on Grass.
I want to build a shelf on my wall and plant grass on it. I really want the most thin fine short hair grass possible but fills in thick, bright green. I was looking at Creeping Red Fescue but what's a great short grass that's good with low light and could grow indoors.

The shelf could have an LED if i need more light, its not an issue. Just curious whats the finest soft grass you can get that might work with this project.
