Like I said in my other post this is my first scrog and I was wondering like how to get the plant in the fencing like do I just let it grow up into it do I top it and let it grow or do I let my plant grow first then pull it thru and I see all the pictures of a flat scrog and there is a bud every couple inches and filling the screen how do I get that to happen
Scan through here for the tutorials, study those pics I posted for you in the other thread and I'll dig up a few more that should help (will post here). It's confusing and a bit intimidating to start but once you get going it becomes more clear.
Most folks will LST the plants early to prepare them for the screen then choose a screen height, let's say 12". Once they reach the screen start training them to it trying to align a bud site in each (for example) 2" hole in the screen. I use plastic twist ties to hold the branches in place but some will let the branch grow vertically 3"-4" then tuck it back under minimizing the tying. Planning ahead is important, decide which direction you you will train your branches so you don't "paint yourself into a corner" so to speak. Keep in mind that when you flip your photoperiod for flowering (12/12 for example) your plants will experience rapid vegetative growth for 1-3 weeks, you should plan for this and use that period to complete filling the screen. The goal is an even distribution of bud sites across the screen allowing the light to reach all of the canopy equally. A ScrOG is about maximizing the potential of the strain you have selected, the space and lighting available allowing the plants to reach their full potential. Bear in mind that different strains will respond differently, a 2" screen may be perfect for one while that might put the bud sites too close together for another once they mature. I hope that helps answer your questions but there is no substitute for research and experience. You'll get better with each mistake you make, cannabis is hardy, do your homework, pay attention to the plants and you'll be fine.
