When to change light cycle for SCROG?

Not I, but @HappyHydroGrower and @Growingforothers and @AfgVet all do nets. They’ll have something more to offer than I can.

No worries. It’s on my “to do” list but I’m waiting til Growingforothers and I are growing something together to get a hands-on. It’s one thing I just can’t find the motivation to do/learn on my own

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.
Check out @nug61 Maui Waui on the scrog table
you will have to scroll through to find what you are looking for. It is a good example of using a net.

Thanks @beardless … but you are correct, i will be using 4" or smaller from now on. Hoping i nail the 4 pot under the table on a true scrog next run. :sunglasses::v::heart:

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.

Welcome to the SCROG world @spacey

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

My first grow I flipped way way too early. And it didn’t stretch nearly as far as I wanted it. This grow I let it fill out till it was about 75-80% filled before I swapped to flower.

Thanks @Graysin

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! :+1:t2::v::sunglasses:

Dont know why most prefab nets from manufacturers are 6" squares. Not the best in the early stages to me?

They can use mine as an example of not small enough squares…you basically end up with a SOG instead. Although karma was on my side this time and they both fit under one light when cut the nets away. :sunglasses:

It worked fine on my last grow as it yielded 272 grams from 4 plants, 6" squares is a choice lots of people prefer.

My last grow was my first SCROG, it worked out great with 9.5 oz from 4 plants. It’s more work but I like it much better than just HST topping.

I’m using 2" x 2" mesh and will use 4" trellis net for support once they get tall.

Looks great. What percentage do you get to when you change your light schedule?

I think my 6" squares ended up okay because I had topped the 4 plants 4 times by the light cycle change. Probably not the most efficient method, but I had more bud sites than I needed and had to cut some out.

I disagree since my last grow with all Sativa’s was 8.5 weeks from light cycle change for a Strawberry Cough. It may take shorter or longer, I think it just depends on the environment plus the strain. Type of light, RH, temps can all change your flowering timescale.

I wanted to get as close as possible to 85% and flip. Then keep tucking after flip to fill the rest in as the pros here have all mentioned. Lol.
Still on my first grow and winging the hell out of it. :joy:
