Indoor Growing Scrog

Thx for the warm welcome. Was a bit busy, to instantly reply. But here's

I still use lot of my stuff from 20 years ago as well as what is available to me and does the job without breaking the bank.
Have to order some tubing , connector pieces and some fresh drippers , as my old ones were a bit too done for my taste. But other than that, I guess I've more than enough stuff to use.

For the scrog project I stay indoors with a 140x70x200 tent this time. Never used it , but a scrogged plant is shitty to move and when a maintanence guy has to come for whatever repair reason it's less stressful to just close a tent.
2 150watt led should work in that tent. i've also some left over filmmaking light led panels, which worked surprisingly well for under canopy in the past.

While not needed now, I still found 5 of the metal frame shown below, which looked pretty useful (it's 100x90cm). The metal on top are two fence elements.All could need a cleanup and bit of fresh paint. These fences are heavy and hold everything down but literally any net would work.
I don't think about using this indoors ever, but outdoors one day in the future this isn't that bad to have, especially if the roof elements are added and all 5 frames are connected. But puzzling the roof parts together is pain in the ass with no helping hand , just imagine it for now.
The still tiny outdoor grown zushi below is just to illustrate the idea of the frame better.

Our local "we sell only random crap nobody ever needs but it's so cheap, you buy it anyway"- store had - surprisingly- a small batch of these wham boxes in 36l and 62l for a undenyable price. On top another old pump and some timers.

Looks like you found yourself some cheap hydro parts bro. Always nice to find things at the thrift store or around the house to make your own grow equipment. I used scrap lumber that I had sitting around the yard and cut sections from an old rusty dog pen to make my outdoor scrog racks. Had to buy the casters (wheels) and some wood glue but that was about it.
Your outdoor scrog rack should work well. You can make more areas to tuck by just wrapping wire on the grate in a strait line if you have too much spacing.

She’s looking good @Carl_Crane420! :mrgreen:
Canopy is filling in well and you have plenty of top sites for a high yield.
Great job on the defoliation! How often are you stripping her down?
 
We should get you some of these in the feature : https://dutch-passion.com/en/cannabis-seeds/red-tropicana-cookies

You up for it?
That sounds so delicious! At this point I'll run anything you suggest. I've only been impressed, and would be extremely honored to run that! So trip out, I'll post pics tonight but the SMC is fading purple in rings! Never seen it before but imagine a bud from top view and the tips of the leaves are green, then fade to purple, then back to green, essentially leaving a purple ring on the buds. I should be home by midnight and will post pics then! But yes! I would be so stoked to run that Red Tropicana Cookies! Tell me what I gotta do! I'm getting my iPhone back so will have good pics again tonight when I post!

Oh, didn't thought about that extra wire solution to double the number of free spaces. Good hack. Will steal that idea ;) thx.
 
Love this thread, it's great information on here. 420autoflower scrog method rocks. Thanks for sharing your knowledge and the beautiful pictures. This needs more attention in the entire community.

I'm trying your scrogging in the next run in a slightly different yet the somehow same way , with some DP photos instead of autos, just not chosen which exactly. Probably it will become another zushi since I have few ready to scrog within next 2 weeks. Yet I'm open for alternative ideas, recommendations etc...
Could be fun to document , photograph and share the progress.
My last two scrogs in the 2x2x4 have been with Dutch Passion Photoperiod ladies and they have done stellar! Really proper genetics, not a bad word to say about em! I say if you're going for that super yield type of scrogs, choose something with a little more sativa in it so you can maximize the potential of all that stretch and cast less shadows from thinner leaves!

Here is day 18 since sprout on my autos, I'm running the 8.5L pots this time, rather than 15L Autopots, just to save on some coco. No need for
larger pots, I guess. Just leaf tucking, no topping, no LST, nothing. I want them to grow as stress-free as possible until they get slapped heavily with the net.

I'm planning to do the same scrog method with 4 autos in this 150x150 tent, just without the rockwool setup you use, because I absolutely don't understand how that even works. Yes, I'm stupid. They're getting around 300-350PPFD at 24/0 currently, I try to keep DLI a bit lower, just so they get a bit more of a stretchy growth, without being too stretchy. This should avoid the dense node growth, which usually makes stems break heavily if I would try to scrog them. Just right in the middle, pretty much. EC floating at 2.1 with Cropsalt Veg A/B + TA Pro Roots + GG MSA at 100% strength, PH floating at around 5.7-5.8 in the res, causing a tray PH of around 5.9-6.0, which seems perfect to me.

They're at 350W of power with the GrandmasterLED Tarantula Ultimate 5x5, so around 35% strength. I plan to not really raise power any higher than this, maximum will be 50% power or 500W of powerdraw in flower, but only theoretically, depending on how these plants grow.

Temps are spicy at 29°C, humidity floating at 65-70%, which makes a perfect VPD including the leaf offset of around 2°C for veg.

@420autoflower or anyone else - When is his usual timing to flatten these plants out? My search function does, for whatever reason, still not work. It says I have no rights to use it, and I don't know why. Account is confirmed, I'm clueless, so I have to ask here.

Welcome to AFN that’s weird you can’t search here’s some notes I took when I did his 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.

Best time to scrog your autos is about 7 days after you see your first pistils. That’ll give you enough preflower time for your small/weaker nodes to grow and stack, but not too much preflower time where they’ll get too tall and pressure you into rescrogging. If you scrog too late and dont have enough preflower time the middle of your canopies will have a hard time filling in and might leave you with some bare spots.

If you’re going for the 420 method timing is very important so good to scrog out your autos 3-5 days after seeing your first preflower pistil or about 10 days after flip with photos. This allows the last remaining stretch to be done under the net and by keeping all your main branches pointing horizontal the energy will be diverted to the smaller nodes in the middle which helps create a nice canopy of colas.

5-7 days after your first pistils show with autos

I’m constantly defoliating starting from day 20 but I do my first leaf strip (schwazz) when I’m prepping them for the net. I’ll do 2 to 3 more during flower but it all depends on how much foliage each individual plant grows. The first Critical Orange Punch I just posted required 4 schwazzings to get her to where she is and the other Critical Orange Punch only needed 3 rounds, so the amount of pruning varies from plant to plant.

I bend the main top over with a bent coat hanger stake at day 16 and keep the top pinned down for a couple weeks which helps promote more mains and a lot more side branching and I’m also guaranteed the largest kolas from not topping.


I flatten the plants out about 5-7 days after I see my first preflower pistil and that usually gives me another couple weeks of preflower stretch to help my weaker lower nodes stack and grow into huge kolas. Even the nodes at the very bottom of the plant that usually gets picked off (lollipopped) grow into big kolas. If you scrog out to early the lower nodes grow too tall and you end up with more larf from no light penetration in the middle of the plant and if you scrog out to late the lower nodes don’t have enough preflower time to stretch and stack. Timing is very important with this method!

Autopots rock!! Your plants look great! After a couple grows I switched to the tray2grow and love it, plants love it too highly recommended! Coincidentally mine are also 19 days old today. A little diff approach as I started the sprouts with 2.0 EC and 38 DLI but it’s not how you get there as long as you get there!
