Second SCROG attempt. In the below photo the front 3 plants are Indica autoflowers and will be finished around 5/10 so I’m not doing much LST on them unless needed.
The back two are Sativa photos I want to SCROG and they’ll finish about 8 weeks after light cycle change. I want to let the photos take over the trellis net as much as possible since I like that strain better anyway, and they’ll have more room after the autos are out of the way.
I read a few times here on ILGM that people change the light cycle to flowering around 75% or so of the horizontal coverage they want, because there will be a growth spurt after the change to 12/12 light.
Is that right? Should the growth spurt be allowed to go vertical only, or is the growth spurt part of the horizontal growth to fill in the net with bud sites?
First welcome to the neighborhood @spacey , nice plants you have there. I’m not a scrog guy but have seen many of them and you want to weave the branches of the photos into the net keeping them in the net so you have a flat top and have it 2/3 or so full net then switch light schedule continue to fill the net while keeping the plants flat as possible they will stop growing and actually flower after a couple three weeks from the light change. I’m gonna add that flower weeks don’t start at light change so expect another three to five weeks from light switch. This is pretty much my best instructions from my memory of reading and watching. For more experienced help I’ll tag a couple people my old brain can remember does scrog @beardless@OGIncognito@JJ520@Audiofreak@Low@pr@Graysin I know there are 40 more in there but my old brain can’t remember them right now
Welcome aboard. Im still figuring out the scrog thing myself, so ill be paying attention rite here with you. Seems everyone has their way of attacking it, so thru trial and error, we just need to find what works best for us. @JJ520 and @Low are two grows you should check out. Happy growing !
It totally depends on available space, lights, etc. I can not see the net you have to be of much use other than getting in the way. To scrog means to weave branches in the net. That is tough to do with huge openings.

you will have to scroll through to find what you are looking for. It is a good example of using a net.
A couple things I noted on your post, first I think you said the sativas will be ready 8 weeks fro flip? Not a chance in my experience. Probably at least 12 weeks from flip, and possibly longer. Also a sativa will at a minimum double in height, and possibly triple. Here’s a pure power plant when I flipped it, and 25 days later (today). It’s got a lot of sativa in it.
What I do with mine is I’ll let them fill the screen about 2/3 of the way then flip the light schedule. The plants will stretch a bunch after the light change, keep tucking the branches under the net until it’s full and then let them grow vertical.
Good luck with them!!! You’re off to a great start
Welcome @spacey to the forum.
I’m like @beardless here, a trellis net is not the most optimal way to scrog. Why? It’s a trellis net. That is used for support not scrogging.
Don’t get me wrong, some use a trellis net very successful, but if not done correctly will end in less than an optimal scrogging attempt.
Use string and pvc or wood. Let the plant grow through the scrog about 5 or 6” and then pull it under the scrog to the next square. Or, crop it and lay it over the scrog and tie it down.
You just have to do whatever it takes to keep the whole plant growing up at the same time. Most of all, it takes a little practice which will come in time. Good luck and keep’em growin!
