Weeeell,...lol. I've had a few issues with sub stuff but that was a few yrs back. We met up at Harry's in Maine this yr and he had a bunch of cuts for the masses so my buddy Bill took home a tray of goodies and mom'd the best ones. They'll be around for locals to cut from till the spring.
hey LBH, delete some messages in your inbox!!

Cleared out Hawk.
ptj, I think u are picturing this wrong. The sides will be the same height as the mains. No weaving! Let the bud grow a few inches above screen and then pull from underneath and MOVE it to the next hole.
 
Huge kudos to you LBH as well as the many other contributors to this thread. Great job providing a wealth of info.

I am looking for some help after reading this and a bazillion other threads.

I am just getting restarted after being away for a few years. My first attempt (about a year long) was a ton of learning and mediocre results at best. I would like to try again using this scrog method and would love a little advice.

I am building a 2 room operation with a 600w on veg side and a 1000w for flowering (mainly because that is the equipment I have leftover from last attempt). Floor space is plenty as I am dividing a 200sqft room. Ceiling is 5 feet tall. I have a bunch of equipment left over plus a decent budget to build with.

I would really love to build along these parameters:

-90% sativa...probably Kali Mist
-want to automate as much as possible...especially watering
-a perpetual operation

I guess my first questions would be:

1. How big of a screen can I put under my 1000w and how many plants? (I know it partially depends on veg time...)
2. Dirt or some form of hydro? I lean towards hydro but not stuck on either. I just want what will be easiest to work with and most effective.

Any help would be amazing:) I'll post the results here as it moves forward.

I'll need to set up the whole thing from scratch but see it as an chance to do it well form the beginning....
 
After reading some more....now I am thinking of putting a mover on my 1000w and running it over 2 smaller screens. Each screen would have its own independent irrigation system etc.Might be easier to manage than one big screen.

Later today i will map out all of the areas to be considered such as lighting, ventilation, humidity and temp. control, odor control, growing method and medium as well as irrigation. I'd love to share what i come up with if there is any interest or support here.

Thanks again guys:)

Movers are awesome over a screen but be careful which one you get, some are really cheesy. I think there's a guy here in RI who makes some real bully ones but I don't know if he makes em for single lights. The ones I saw held 5 each

With a 1000, I would do 2 plants, each with a 4x4 screen so you'd have an 8x4 path to cover with the mover and most movers come with a 7' rail, perfect. No reason you can't pull 2 pounds from that screen with a 7-8 week veg from seed. Grow 'em up!

Bro... that's by far one of the cleanest, most well-planned out and Organized small Ops I've ever seen. Hat's off to you. Superbly done. If you're not a consultant, you damn well should be. Rep Rep Rep.

Thanks guys, glad it could help. Stay tuned, we've figured out how to get same results w/o the screen!! I'm making a tutorial with the next run :-)

Only thing is the fence doesn't give. Its a great idea as for a reusable screen but I like to use string for a number of reasons, biggest being you you can manipulate it, like stick your hand through the screen to clean out the plants, etc.

The layout of the plant itself looks good but is done the traditional style. This particular scrog method in this tutorial is different in that you use specific training in veg to grow a short, wide plant allowing you to get the screen down to 6-8" so that undergrowth that is normally stripped can become useable, viable bud. For traditional scrogging like your plant, I suggest lollipopping it just after the stretch.

Doc- Scrog means screen of green, You got no screen! lol (Plants look good though)
When you say traditional scrog what do you mean? I thought the traditional way of scrog was to train the plant into the scrog by pulling branches under after growing a couple inches above. I see you're familiar with some TGA strains, are you familiar with mainlining by any chance? I mainlined my second grow, about to harvest tomorrow actually. I wanted to attempt to combine scrog and mainlining, or rather your 4way tutorial with mainlining to create two even halves for the scrog filling a 15"x26" U/stadium scrog.

never mainlined.

By traditional scrog, I mean, letting the plant grow (up) and tucking the branches while sometimes raising the screen incrementally as you go and when ready to flower, you strip everything under the screen. With the 4-way method, you top immediately and get the plant growing sideways in 4 directions (horizontally) instead of in one direction (vertically). By doing this so young on, you eliminate any "under screen" buds,...they are all up in the canopy. To help understand, imagine a 12-24 inch stalk with a bunch of scars from removed arms under the canopy with traditional scrog and an 8 inch untouched stalk with a 4-way lst scrog. Canopy is much lower than with a traditional and you dont stress the plant with amputations.

another benefit to this, is if you are in tight spaces, like a closet where there is significant heat build up at the ceiling,.....keeping the plant lower also keeps it further from that danger zone

Oh I understand now. By having multiple tops already spread out by training since much earlier it's easier to get it into the screen than not training very much. Attached is my plan of training for this coming grow (and some bud porn from todays harvest), do you think I should include the mainlining step or go straight into your 4 way LST? The mainlining step is to ensure that both sides will be as even as possible. It will also make harvesting easier at the end, where I will just snip her a the stalk and do the full plant dry and trim afterwards.

What I'm trying to ask is, do you think it would be worth it for me to include the mainlining step, or since ultimately I will be filling the screen either way perhaps it doesn't matter as much. For reference, my dimensions for the screen are going to be something around 30"x15"

oh, ok, now I know what mainlining is. Ive seen this or something very close in the West Coast Masters book. The formula they use is 1x 1000w on 1 plant in a 30gallon res and a 4x4 screen for 1 pound per plant. The mainlining gives you 64 colas, 7 grams ea (thats the goal anyway, some do better)

This is the style they are using at our first compassion center here in RI. (the center is allowed to grow 99 plants)

This style will give you a higher yield than the 4-way method but needs a much longer veg time so it's tough to do perpetually. The 4-way is PRIME for tight spaces, especially height restricted where you wouldnt veg longer than 6-7 weeks but if you have the room and time, mainlining will be a better yielder.
 
Hey LBH, just wanted to say thanks for all the info. I actually started my first grow ever and decided to scrog after reading your tutorial. I just flipped the switch to 12/12 yesterday. No problems so far just wanting to know how to provide the best ventilation possible since my girls decided to branch like crazy from the get-go and they may get a little tight. Any advice would be much appreciated. I can provide pictures if I knew how from my iPhone ha. Much respect, sir. And happy growing!

Vent them as much as possible. I like having a fan under the screen blowing up,just a light one though, u want o move air thre the thick canopy and also push heat up but too much air and you'll push it back down again.

LOL... sorry but I should have been more clear. Do you plant in streight soil, use rooter plugs, ect.

Since this is a type of hydro... 50/50 coco/hydroton... should I use 10 gallon smart pots as well or do you think the 5 gallons will be good to go?

4 week veg or until the 2/3 of the screen is filled then fliping. 9' x 6' screen. 9 week flower.
