Indoor Growing Scrog

What are the typical days since sprout that you must apply the 420scrog net? I realize there is a range depending on variables and culivars. But I appreciate anyone's numbers or guesses. Thanks all.
In this thread there have been plants that were scrogged less than 30 days after germination and some even after 45 days. I'd guess day 35-40 is a reasonable timing if one wants to slap a tentative day number on the matter. Take my guess with a grain of salt, 420 and DOA know better for sure.
 
So, I do stop tucking and weaving when they basically don't stretch anymore? I'm wondering, because, your results are showing kind of big/tall buds/colas.
Or do they still stack up / grow taller aswell naturally even if the stretch is almost done?

Is there not a point during stretch, where I have to stop tucking and weaving and let them grow tall / stretch vertically a little bit? To get taller colas (and more yield)?
Sorry, this is my third grow total and first one on hydro. So I'm not really super experienced. But try my best to learn as much as possible.

Here are some follow up pictures from today.
Some more data first:
  • Today we have Day 43 since germination.
  • Growing different strains.
    • Glue berry, Daiquiri Lime, Critical Orange Punch
  • First pre-flower pistils shown on day 28. (first plant. the other 2 plants showed those 1-2 days later)
  • Flattend out on day 37
  • Since flatting out, I tuck and weave once a day. To keep (main) tops down.
  • Here and there I remove some leaves to keep very dense foliage clusters under control
    • Also, to expose smaller nodes / tops.
All of them are still stretching.
But as you see in the pictures below, at least one plant has significant flower-production already. I'm worrying how much longer they still will stretch. I hope I got some more time of stretching to grow these ladys taller.

Today before tucking and weaving

Today right after minor defoil to expose some nodes.
(you see the difference especially on the below right plant)
And after keeping tops down etc.

One plant is still in very earrly flowering process

Second plant a little further regarding flowering

Third plant. Flowers already more mature. Hopyfully they will still stretch more I guess.

You’re doing just fine Brother! :headbang:
All 3 are looking great. It’s difficult sometimes to judge the amount of preflower time each plant goes through with hydro but the close up pics of your tops gives me a better idea of how far into flower they are.
You still have a fair amount of stretch to go with all 3 and the late bloomer is definitely going to grow into a monster with how much preflower she has left. She might even need to be rescrogged after her stretch to maximize full potential but not sure if that’s an option. I had the same problem with my 2 Glueberrys I had growing side by side in a 4x2’ tent but I eventually bought a cheap $49 32x32” tent and split them up. Glad I did as the larger one wouldn’t have produced nearly as much and I would’ve ended up with a bunch of undesired fluff bud if I left her in the 4sqft she started in.
I would let the middle of the canopies grow up while keeping the tops on your main branches tucked, and give them another heavy defoliation after your stretch as @DOA advised. By keeping your main tops pointing horizontal most of the energy will continue to be diverted to the smaller nodes in the middle and help create a full canopy of colas
The hard work has just begun bro and it’s going to take a lot of canopy maintenance to get them across the finish line with success but we’re all here to help and you’re doing a fantastic job already. :thumbsup:
Hard to believe it’s only your 3rd grow. :d5:

They're coming along nicely. :thumbsup: good things to come.

I would give them another big defoliation before you hit full flower mode ;).

You'll see and get a feel for when stretch is finishing. Once you have all the bottom nodes filling out the centre and the outer nodes filling out what space you have that just let those tops grow up. From about day 55ish all the kolas should be in place and then then allowed to tower and fatten.

Really pumped to see how you finish up, from what you have there I can see a yield of 800g+
Thank you Brother! 🫵
So nice to have another sensei in this thread. :thumbsup:

Going back again to an earlier post of yours, 420, in an effort to replicate this formula:

Do/did you keep your Floranova Bloom and Koolbloom ratio consistent throughout the flowering or gradually increase the relative amount of Koolbloom? (for context: GH recommends Koolbloom, a 0-10-10 PK additive, to be added in the two last weeks of the cycle – so giving it that early differs quite a lot from that recommendation)

Also, do you progressively increase feed EC till the end or dial it back it at some point(s)? (saw that in an earlier post you said that you go from 1.3 EC on day 7 to end up at 2.6 EC)

I was also wondering whether it'd be a solid choice to switch to said flowering nutrients once one sees pistils appearing at the ends of nodes or to do the switch already before that.

Preemptive cheers.
I start running the FloraNova Bloom and also supplement with Koolbloom after the stretch. During the preflower stretch is when your plants grow the most which is the main reason I run FloraNova Grow all the way up until after the stretch is done to avoid any deficiencies.
I don’t really pay much attention to the manufactures recommended dosages and rely mostly on what my pens tell me. I usually add about 10-15ml of Koolbloom to a five gallon bucket of R/O after my base NPK and that always leaves me spare EC (PPM) to add in all the other goodies I like supplementing with.
I use to bring my EC up to 2.6 during late flower but came to the conclusion awhile ago that my autos will still flower hard without such a high EC.
1.5-2.0 EC should be all you need to grow fat dense colas.

What are the typical days since sprout that you must apply the 420scrog net? I realize there is a range depending on variables and culivars. But I appreciate anyone's numbers or guesses. Thanks all.

I like to scrog out about 5 days after I see my first preflower pistils, however sometimes that’s too early and I end up having to rescog after the stretch to maximize full potential. As mentioned above… it’s difficult to judge the amount of preflower time/stretch each auto will go through with hydro but with the 420 method scrogging is always done during the preflower stage.
 
Dayum people are pulling it off real nice!
Yes Bro!
Happy to see the great results. :lol:
Your photo should be interesting to watch develop. :thumbsup:

Roc @ rocbudinc is the breeder
Just took a peak at their site! Looks like they have some nice cultivars. :mrgreen:
Might have to run a few in the future. 😉
 
You’re doing just fine Brother! :headbang:
Glad to hear that :woohoo1:
I'm also satisfied with the progress so far. :cooldance:

Good point. I wouldn’t have noticed that on my own. What do you think would happen if I tried to keep the late bloomer under control as much as possible and leave it in the tent?
I guess the harvest time would be delayed. She might also grow much taller than the others, resulting in an uneven canopy in terms of height?
And, of course, I wouldn’t get as much yield unless I re-scrog her in another tent. I’ll have to think about that. Theoretically, it’s possible to move her, but I’d need to prepare it next week and buy some extra stuff.
Since I’m using a scrog net, I can cut the plant out if needed.

Thanks bro, got it!

:toke: Appreciate it. But I have to admit that over the last few months, I’ve been researching and studying the topic like a maniac.

Thank you Sir! I'm in far western rural NY state. I do my legal 3,and because of tight narrow weather window outside for maturing here on a hill, need to plan within about 2 weeks, starting indoors before moving outside and doing 420scrog. I can't set outside too early. Will start indoors next month under HLG lamp. I use a table, no tent. Been saving and studying everything 420autoflower (the absolute Master of Grow) has published online and as s former nurseryman this project is a must. I'm stoked. I just love growing nature's medicine, although I use it in moderation and can give away to only a few. Been at it since 1967, Oregon was great. It was all bro-science and experimenting then. Got nervous every time you'd hear a plane or copter.
 
Thanks again for helping out!

Here is my first grow using the 420autoflower scrog method! These plants are at day 33.

First pre-flower pistil was seen 3 and 5 days ago. The third plant still doesn't have any.
Question is: Should they be flatten out right now or should I give them a few of more days?
Since I have the feeling, there is still no stretch seen yet and I'm wondering, if I should let them grow/stretch a little bit taller. What do you guys think?
I plan to move all of them in a 1m x 1m tent (~3,28 x 3,28 feet).

What is 420autoflower scrog method! How does it differ from the regular scrip method? How do I find out more about the 420autoflower scrog method?

This is probably the exact place, y oh might have to start at page 1 though
 
As I understand it, the method is a simultaneous combination of scrogging (applying a net), schwazzing (heavy defoliation of fan leaves) and super cropping the branches that need it – to achieve a flat and relatively, at least initially, low canopy. All of those being done when the plant has been in its preflowering phase for a while.

But do yourself a favor and look through the thread, it is worth it (remember that the search function can be used as thread specific). If you think it's too much time it'll pale in comparison to the amount that you're going to be defoliating and tucking a vigorous plant.

Late bloomer will be fine where she is but as you already mentioned she’ll be behind the other 2 and possibly taller. You have all 3 set in there really nice and you did a wonderful job scrogging them out so I would just leave them where they are.
Keep posting updates and I’ll do my best to advise accordingly.
Excited to see your cola packed tent soon! :mrgreen:

Hello There,
Glad you found your way over here. :d5:
Will you be growing your autos in a climate controlled greenhouse? Would be interested in seeing your setup. 😉



What is 420autoflower scrog method! How does it differ from the regular scrip method? How do I find out more about the 420autoflower scrog method?
The 420 method is a lot different than your typical scrog. If you thumb through the thread you can see that my autos are grown naturally with basic LST started around day 15 and then completely flattened out down to the base of the stock during preflower, which is not done in your average scrog. The net in a typical scrog is used to even out a canopy or cola support and with the 420 method the net is for training only. There is also no lollippoping under the net like you see people do in a regular scrog and a lot more defoliation/canopy maintenance is required with the 420method. There’s absolutely no waste with this method and even the smallest nodes turn into some of the largest colas on the plant.


This is probably the exact place, y oh might have to start at page 1 though
Thank you Brother! 👊🏼


I've been studying from page 1 several times and get lost and start again but lots of info here but lots of pages to go through
The thread should give you a good idea on how the method works and feel free to ask questions. Have you built your PVC rack and system yet?
