Indoor Growing Scrog

[420autoflower]

Hey 420, thanks for all you do and showing your process along the way my friend. I've started a new grow (as of yesterday, 1st Dec) and am looking forward to replicating your methods with the wealth of advice your have shown here and on Reddit. I'm super excited to share my grow and ask advice along the way.

You’re very welcome Brother.
Been very busy and might take me awhile to respond to questions but always happy to help.
Thanks for sharing your new grow with us and we’ll try to advice you the best we can.

420, some questions: Are you running two 100 watt lights at 100%? Are they about 24 inches above the canopy? And if I remember correctly, you run them 24 hours? Are those numbers the same through each phase of your grow? Thanks!

Yes, I run my lights 24/7 with every grow.
Most of my tents have $109 240 watt FarmLites up above and $39 100 watt Maxisuns turned down to 80% down below. I did have 4 Maxisuns wired together for over canopy lighting in my 3x3’ but I recently bought a $150 500watt Bloom Plus Pro that I replaced the Maxisuns with.

As far as I know, 420 uses different lights with varying wattages. But the 420scrog method is more about the training (and timing) of autoflowers, including choosing the right grow medium with optimal fertigation. The lights run 24/7 during all growth phases.

I even remember he once used a cheap 150-watt grow light and managed to achieve more than 7g/watt. So what I want to say: The focus should be on optimal training and timing, like flattening out and defoliation, canopy maintanance etc.

You got it buddy!
There’s a lot that goes into the process as you already know.
Lighting is important but good nutrient management, pretraining, HST, timing, canopy maintenance and defoliations are all necessary to make it work right and to get the best results.

@420autoflower @DOA (and everyone else )

Do you think it's time for a "real" schwazz-session? (For plant no.1+2. The late bloomer still getting light defoils, but not too heavy. She is still in first week of flower imho).

I did leave tucking and light to medium defoiliation along the way.
I've got the feeling they are still stretching.

Very nice!
Beautiful full canopy you got there bro.
Good time to strip them down!
A lot of work but well worth the effort.

I am going to pull (almost) all of those fan leaves. Schwazzing. The question is, should I do it right now? Normally people say after the stretch is over / after week ~ 3ish.
Or should I wait a little bit more until the plant focuses completly on bud development.

Go for it!!!!

Consult with our Oracle, but to me they're blocking bud sites, and I'd pull at least those.

Perhaps I missed it earlier? It looks like, besides stacking Grodan blocks, you place large sized starter blocks on top of coco (or is it soil?).. How do the results of the hybrid stacks compare vs. just blocks? Why and what is the difference between the blocks apparently set on top of the coco/media vs. the blocks apparently set on top of a white plastic sheet on top of the coco? What does the white plastic do here?

I start all my autos in my signature 4x4” Grodan cubes and after roots penetrate through the bottom I place the cubes on either a 2 gallon grow bags filled with Cloud Coir coco/perlite, Grodan 6x6” Hugo blocks or Grodan Grow Chunks. The Grodan 4x4” cubes are great to start in… they don’t take up much space, absolutely no risk of transplant shock, extended veg and preflower time and they boost my autos up 4 inches so I’m able to scrog them out without being to close to the medium.
All the different mediums perform basically the same but makes the grow a little more interesting and shows people what kind of results you get with different hydro substrates. The white plastic (panda film) is to cover the Grodan Grow Chunks to avoid algae growth from the light.


Thanks for the reps @Mossy and @DOA!
Much appreciated folks!

If it were my grow I'd be having all those leaves off now, convert all that stretch energy into those budsites. As you move into late flower, the only foliage you really need are the sugar leaves. Once you hit late flower those little leaves will have enough surface area to get you to the end.

Thanks Brother!

Maxisuns

I landed a good auction deal earlier today on another of the farmlights, the 260watt

But i guess it will be a complete reset after tossing like 28 clones in the trash after seeing more spider mites

Sorry Bro!
I hate spider mites.

OK, Im getting my new system together

8 plants of autos are going in early flower , I scrogged them a little late because of the system setup start and missing parts, so I scrogged them I quess in the start of flower and they had starting of pistils in the top parts of the nodes, not only in the middle of the lower branches.

Im running temps 23-24c and humidity about 55-60rh, planning to take it to 45 when in midflower in a about a week from now.
Keeping temps 21c in the reservoir.

I quess they are in start of flower week 2 now, dont really no how to say.

So im using wilma drip feed, right now feeding them 15min x 7 times a day 24h lights on. EC 1.8-2, lights are hortimol 600w, and maximum power at 50cm so i guess about 800-900 ppfd. ( waiting for the diffuser to arrive to get exact figures from my phone app).

I have to admit I messed up the wilma feed in veg 1-3 weeks, this is my first Wilma grow or any big grow. I had them on only hydroton clay pebbles and were feeding them 2 times a day, which wasnt enough ... dumb me, but that was wilmas clay pebble instruction... and the ec was also too low, so it really stressed their growth, changed them to hydro 40/coco60 in veg 2-3wk and feeding 5 times a day and the veg time was something like 7-8 weeks all together, they started to really grow after a couple of days stunned after the medium change and optimal lights and nutrition.

Rockwool 4x4 my starting medium is inside the hydrococo, maybe nxt time keep it on top of the main medium.

Most of them are topped and had LST also, which im thinking I wont do next time only coat hangers, and the preflower defol and scrogg ON TIME....

I updated today 6 pieces of under canopy lights bloom plus 90w, and took the pics

Now my setup is:

8 plant wilma drip feed
6 x under canopy lights 90w
2 x 600w hortimol main led lights
1 x hps 300w main light

Also I have 2 far red lights than I am planning to start in upcoming days.

So I could say this is a learning / training grow because im just starting this bigger growing scheme with the scroggs.

........

I also got myself dutch passion orange auto critical punch seeds, and trying to also get speedrun auto granite haze seeds for my upcoming grow in 2 weeks which im strating in a different veg tent with another 2 x 4 part wilmas, so I can get them in the flowering room when my learning grow is put in the veg tent to dry, and the new vegetative ones to preflower scrogg in the flower room.

........

So what have I learned this far..

- Lots of medium stuff, ec stuff, lights stuff and mistakes on my part.
- Scrogging needs to be done earlier
- Will only use like 2 different strains next time speedrun, and dutch passion Im thinking 4 and 4
- Also I dont like these big holed scroggs that I got, maybe should have gotten ones with smaller holes.
- Im not expecting big results with the extra hps on in the middle , and the far red light but lets see....
- Maybe Im separating the 8 plant wilma reservoir to 2 x 4 reservoir in the flower room, I have a 1 x 4 plant wilma in the veg and have to get another one there, maybe just do it myself , and get it cheaper.
- Streching the nets to maximum widht in the middle next time with side frames to it, maybe Ill get 1,2m from now 90cm
-Vegetative LST in plants done so that it will fit my nets better.


These pics are like start of week 2 flower, defol done too late, 9 days ago and 8 days from the start of scrogg.

.............

The 2 scroggs are like 2,4m x 1m each , and are not streched maximum at their width could have gone like 1,2m im thinking about rescrogging them in the next defol in 1-2 weeks from now.

- What do you guys think is it to early to start with the under canopy lights, in the start of 2 week flower ? should I start them later

- How about my rh 55-60 right now is it too high ot low and how about the temps 23-24c ? Im planning on lowering it to 45 maybe a 1-2wk from now.
Im keeping good airflow under and in top of them and putting more of them upcoming weeks.

Those lights look awesome! Stoked for you!

Living here in the EU, I am envious of the fact that you can waste so many photons and not worry about your electricity costs... ah well, maybe one day.
