Let's Edge It! Decorative Plastic Brick Edging with 4 Built-

Can u stack

Would the solar light charge enough with only a couple of hours of sun exposure during the morning? The rest of the day they'll be in a shaded area.

Can water on soaked grou get in through in between each brick? Can this be used to make a mini levee to divert water from heavy rain during flood??

I am looking to use them around a small putting green and I will only have 1 inch for the spikes. How long are the spikes?
