What should the spacing be on the net? 2x2? 3x3?
i would go with the 2x2, more holes for tops.!
3x3 would probably be easier to use tho.!!
Either will work.
I do 4x4 but I tie mine down on top. The opening is basically for the plant to get through where at that point you force it to grow horizontal.
@Grandaddy013 I’m not getting it. Do you have a picture to show
I prefer 3x3 inch squares or else you run the risk of running colas too close together. I’ve ran both and prefer 3x3” squares personally 
Once the plant grows through the screen approximately 8", I super crop them over and tie them down. I keep tying them down as they get longer. When the screen is about 60% or so full, I flip the lights. I continue tying them down until pistils appear. I did 4x4 nets, and 4" spacing worked out good for me.
Nice super cropping 
. One day I’ll be brave enough to try that 
It was scary at first, but the girls love it
I’m sure . Most of them do!
Those are some nice buds in that other picture. You look like you’re pretty far along
Oh yes I do remember when you posted your Harvest. You still got a nice haul out of it.
Bigger is better imho but it does take a little longer to fill up
