I like a more firm scrog that doesn’t bend too much, as compared to the trellis nets. I made mine with 3/4" pvc screws and string (3" squares), For a 4x4, I would use 1" pvc. with screws and string.
You can attach it to your tent poles using zip ties like this:
The zip tie on the poles are just tight enough so I can slide them up and down the poles as needed.
If it were me, I would trim everything off of the bottom third of the plant.
Thin out some small branches that won’t make it to the net.
Thin out some large leaves blocking the light near the top.
Flip the lights and put a scrog on within the next 2-3 days.
Let the scrog set down about an inch or two and start tucking branches to keep it all level.
Prepare a second scrog.
Over the next two weeks, continue to tuck and train, (may have to use ties to hold her down.
About the time the first bud site start to show, I would put the second scrog on, and adjust the height accordingly. Usually not too much tucking after that. They may continue to stretch a little more.
Here is an little visual example of how rough I get…lol
7-9 before defole:
7-11 after defole and adding scrog:
Flipped on 7-17: 2 days later 7-19
Two weeks later 7-31
Ok here’s one more…lol
Hope this helps some. You got this!
