While I don't know if I'm going to use Nets in this upcoming grow, I am going to be using them in the later grow with some photos.
I'm going to get the stretchy kind with hooks at 4 corners, so it's going to be one that I will reuse. I know I can get the non stretchy plastic kind that can be used disposable, but I just like the simplicity of the 4 hooks and the little bit more flexibility of being stretchy.
Now the question is 6 inch or 4 inch squares. I use knitting with 6 inch squares outside, but I think I want to go with 4 inch for inside.
