Let's talk serious SCROG

So im running into a problem... which is the best part about new rooms
Im using this guys setup for inspiration,http://www.youtube.com/watch?v=f4gzjb8UcO4 well kinnda of.. he has a scrubber built in line to the exhaust side. As of now im thinking this is the best route since im only running exhaust off the air cooled hood. The rail and space restriction on the intake side prevent me from insatalling a scrubber on the intake side. If any one has seen a way to build these, your a better searcher than I lol. Any way thats the question after my rambling Just need to find a build page or some info thanks once again.

I am a bit embarrassed but i have to make a correction to a term i have been using for a while, I don't feel like going back over months of posts and correcting it so I will just fess up to it now.

I have referred many times to NFT sprayers and systems incorrectly and I'm sure a few of you caught it and said "hey, this guy doesn't know what he's talking about".

As most of you know NFT systems are gravity fed "drippers" for lack of a better term, they pump water into a channel that contains the root system and the water flows down through the roots into the res. This system does not require sprayers so when i have mentioned "NFT sprayers" I'm sure some of you got a giggle at my incompetence.

In my defense, NFT systems have been very much modified over the years and now it is relatively standard to build an NFT "style" housing for an aeroponic setup, the gravity draining and root channel are left over from the original design of NFT but as opposed to a single top fed water source people are using hoses and sprayers to add that extra oxygen to the mix. When I learned about NFT these where one in the same so my confusion (I think) is valid but it is confusion none the less and I wanted to make that clear to anyone who was starting to think that I'm a derpa derp.

Here is a model of the original NFT design for anyone who is interested.

Thanks for the link to that vid, it was very inspirational. His grow room was clean and organized, I would love to pick that guys brain about some of his setup.

Based on what you said it sounds like you have your hood open on one end and exhausting out a hole? would love to see your setup but I will try to wing it based on what i can gather. His scrubber is great, if you can put a carbon filter outside of the room and use that as an exhaust it may be your best bet. Scrubbers in the room are great if you have the space but not so useful when your cramped.

The one thing I saw that i would avoid in his setup is his intake and exhaust point, they are too close together causing warm air to leave the room and go directly back into the intakes. I imagine the side has to be left open during most of the light cycle to keep that room from baking and at that point having a filter is not really an issue. Thats an assumption, like I said before, I would love to pick that guys brain, the drip feeding is nice and his setup looks solid Really, one of the biggest issues in any contained grow is ventilation and we all kinda do what we can and make it work while lighting scented candles and making ona buckets on a weekly basis.

All in all that is a great template to work from, if you can keep your intake and exhaust as far apart as you can this will be a success.

If I missed the mark completely on your question I apologize, I'm having a bit of a hard time visualizing your scenario at the moment.

Now thats a fun scrog lol!

Thanks for showing us that, so from what we can see it looks like a tie-down method of growing the plant out from the center and from the looks of it, carefully training with twist-ties to maximize space use and avoid having an under-canopy to fuss with. The distance from the medium doesn't matter much because you don't really need to get under there.

This is an incredibly creative technique, I love seeing things like this, people making the absolute best of what they have to work with.

Thank you again, we will be watching your journal to see how it turns out. One question; how do you keep the ties from "strangulating" the branches?

Click to expand...

Thanks, i generally untie tie's as the branching grows and move them further towards the tips of each branch, if that makes sense, so the only bit of the branch that is tied down is the end of it. Also i don't wrap the tie's around the branches, i just make one hook at the bottom to hook onto the screen, and another hook on the other end to hook onto the branch im pulling down. Nothing is knotted, so if the branch wants to grow and pulls the tie off the screen it can, and i'll retie it next time i'm doing some maintenance. Its a lot of work but should look the stuff once flowering.

I can't wait to see it!

That does seem like a time consuming method but in truth its good to spend time with "the ladies" get some CO2 on em and micro manage the grow a bit. Keeping a close watch on every leaf can have benefits, I personally spend almost an hour a day just sitting with mine, looking over the foliage and trying to "see the future". I always catch insects very early and know on a daily basis how well the plants are reacting to nutes etc.

I commend you on your loyalty to the plant, showing it that much attention but using a soft hand I'm sure yields great results.

Me too, going for a dense a scrog as possible. Ideally i'd love to come out with a solid block of bud, never seen it done before though. Depends how hard in go with the tucking and tying, normally takes around an hour or so to look through all branching and do any necessary adjustments. Its not like i mind doing it, if i did, i wouldn't do it! I take care of them, they take care of me, sounds about right.

I have seen a "block of pot" grow before, and here is my warning, mold is an issue with close buds, when they start growing into each other you cant get air in there and they go south fast.

Yeah my exhaust intake situation is perfect. I was just wondering if anyone knew how to build that inline carbon scrubber... Can't find any info on it. Anyway a couple pics to show u im in the clear. Dont mind the shaded pole blower. Its outta there with the 400 and on to the veg tent when i get the new reflector in. the intakes are painted and installed on the door header board. Gotta still go pick up some orca,zipper and Velcro to finish the entrance.

I know a way to do it, would have to build a box around the filter, and draw air thru the box

lemme get on paint rq, i can make a diagram.

this isnt to scale just a quick diagram to give you an idea.

I'll build a smaller version of that tomorrow and post some pics if i can get it done

Nice, now I understand what you were asking about and it looks like the problem is solved! Can't wait to see it in action.

hey a quick question i got a little over 400 watts of cfl and i plan on doing a scrog with my next grow bubbleponics dwc and wonderwoman from nirvana i was just wondering as far as height i know u fill the screen then u flower but how much height will the plant take up in the box im concerned i might not have enough room if i put a 10 gallon rubbermaid tote in there and with the lights hanging i might only have a 2 foot clearance above the screen...

ive heard that the plant can reach anywhere between 15-40cm above the screen, it really depends on the plants, its genetics etc.

Depends allot on when the grower switches the light cycle to 12/12

Just caught up and new here. Great thread btw.

I'm going to agree with both ak.fourtyseven and TT86, not only do the genetics come into play but also the amount you allow to grow above the screen before switching to 12/12.

My knowledge of the strain "Wonder woman" is limited, I have never grown it before but I did read some threads and checked out some of they're genetics before posting this, This makes me nothing of an authority on the strain but I have an idea based on strains similar that I have grown.

WW is a shorter plant, and in my experience short means they don't stretch much after flowering starts, it is and indica/sativa hybrid (like almost everything on the market at this point) so her seeds can produce multiple phenotypes. Without knowing if you will get an indica dominant "lady" or not it is easier in the long run to treat them as if they were sativa, planning for a big stretch and giving plenty of overhead room. Using CFLs cuts down on need for head room so if you start 12/12 before they get above 3-4 inches from the screen you should have plenty of room. In my experience it is rare for scrogged plants to flower more than 12-14 inches above the screen. Even the lankiest strains don't go much above that because they are not forced to put all they're energy into one tall bud. A single bud plant gets super tall because it has to, it needs the one stalk to produce as much "fruiting body" as possible, when using the SCROG method buds are much smaller because there are so many of them, the plant "realizes" it doesn't need to grow tall because the light is hitting so much of it already, instead, it is able to use all of its branches to produce the "fruit" and rely much less on its height to do the work.

That was a really long way of saying you will have room, if I am wrong come back in a few months and cuss me out but I imagine that using this method will have you swimming in so much weed you wont have much anger in you

If you know your strain you can adjust your 12/12 start time accordingly and control hieght above the screen.

Question, I'm planning a U shaped scrog.. with a surface area of around 19 sqf.

I will using 8 plants under 2 x 400 w hps.

From midpoint to top of the screen would b around 23" x 60". Plants will be given approximately 15" width (2 rows). 2 rows and 4 columns.

I'm assuming that I should be vegging until maybe 25" in height, so around 17" (indica) will be on the screen. Does this sound about right? Can I get away with vegging for a shorter length? Or should I be vegging longer?

Please check my math. 23" x 75% (total screen fill) = 17.25" + 8" (under the screen) = 25.25" (to start flowering)

I will using LST in veg using an S type shape as to ready the plant for the U SCROG setup. The S shaped LST will be placed directly under my U shape SCROG for easy transfer.

Will be vegged in ebb and flow, then transferred to HP aero.
