SOG system height question

[Spanishwilly]

What is the actual height needed from pot surface to ceiling in order to run a true Sea of Green with air-cooled lamps?
Really, the question is, can I run it correctly with 1m /39 inches? Again, that's from the surface of the dirt to the ceiling.
We've got aircon, dehumidification and CO2.
It'll be 49 plants/m2, or 4.5 plants per square foot, and we want to keep them short.

Yes , it's down to veg time and Sativa or Indica , a short veg time if any help's with height/space in a SOG . Trimming lower branches before flower help's promote top bud and air circulation below the canopy . Best of luck in you'r venture

One meter is not much to play with. I wouldn't go over 4 per sq/ft. Put the clones straight on to 12/12. If the lamps are air cooled hope the cooling is working really well.

What type of light have you got Spanishwilly.

You will need a really short strain, that also does not stretch in hot conditions, very healthy cuttings flowered very small. Less plants in a ScroG may be easier, also have a look and think about some of the Vert growing solutions... I think I would be going with a semi vert ScroG with tall walls of green at the sides. It can be done, but requires a bit of Green Ninja skills to do well.

Use a indica strain, no veg time

There's also some products out there that will help prevent stretch

39 inches is very, very tight

Hey!
I got the idea from your "My little SOG" thread, HC. I'm planning to use beds like you, except with coco.
I've got 600w HPS in 125mm cooltubes with one every m2.
Straight into flowering is the plan. As for plant density, if you say so, I'll go for 6x6 instead of 7x7 then.
Great to hear from you on this.

I've got Bushmaster to hand if I need it. I really want to be able to work this without that though.

Good to hear from you. Sounds good to me if you can control the temps. Go SOGGING Spanishwilly. You should be fine. See if you can get some pics up.

Cheers.

No veg time, clones on to 12/12.

 

[one Q]

Bare Bulb Vertialby Wisco61 He uses a 400w bulb but shows you that you dont need that much height to run VERT. skim over this thread and see if there's anything that sparks your imagination and get that grow going.

Peace

Hey man... i run large SOG's also... I would NOT recommend cocoa man... it causes unnatural stretch in tight sog's.. your normal 12" transition will end up 20". just food for thought. this pic is of a bed. from the top of the bed to the ceiling is 4ft. im sure you can get yours to work with some careful planning and proper equipment.
good luck!

Hey MAXXIMUS,
Thanks for the encouragement.
Am I being naïve thinking I can use that stretch and go straight to flowering with small plantlets and get a good result? I was figuring on going into flowering at 6 inches/15cm maximum.

 

[dtfsux]

6 inches would be a rather large clone, or a plant that has vegged. IMO way to big for your space.

I grew SOG on a large scale for 3 years. You can use clones that are 3" and flip them. IMO thats what you need. Just make sure they are well rooted.

In hindsight, I guess it depends on the strain. I was dealing more with sativas, and the indica dominant strains did not stretch nearly as much.

Thanks. Yes, just being stoned. Metric/ imperial is messing me up. Hey, how did you root things well while keeping the foliage low?

with coco man, it makes your plants do unnatural stretch. I have found and been taut that 16-17" is best height for a 5'x5' table with a 1k. I use sunsoaker hoods by the way. the key is even light distribution. getting the light to cover the whole table and penetrate deep enough to get good growth in the lowers. with a 6" well rooted cut, even an indica dom strain can end up 25" in a sog with cocoa.
Your going to have to play with it for awhile until you get it where you want it. good luck!

how did I get it to grow big roots, while keeping the plant small?

I rooted in coco plugs under a fluorescent light and left them in for 3-4 weeks. By that time, I had a nice amount of roots, but the plant did not grow in size.

There are some root accelerators on the market that may work as well

Like Maxximus said, you are just going to have to play with it

 

[GDK]

No matter what..make sure u trim them lower branches and watch humidity closely.

Stay Safe

Ok thanks,
I just want all the info I can assimilate before I have to start playing. I really need to get over ten grams per plant for this to be marked a success, and my pipe dream is fifteen.

 

[ChaosCatalunya]

Coco is the Hydro medium that causes least stretch of all I have tried, not sure what maxximus is up to to get it the opposite. My best SoG cutting was flowered at 4" and had nothing trimmed from the bottom, it was all yield.

Trick is to get the mums, propagation and rooting phases optimised at all points, neglect them and they will neglect you.

If you raised your outer plants up a bit, rather than run a flat garden, I bet you will get more than the 10g on those. Try it with half of them and show me I am wrong ?

Good luck SW.

Spanishwilly and I have similar requirements. I want to get my 1k ebb and flow systems to 4' in total height. I've been running big bushes and LSTing and bending the hell out of them but I'm tired of tying up all those lights for veg.

I want to do something with no or very little veg time. I was thinking SOG, but I'm having doubts.

If I have 48" of total vertical space, I need 8" for the reflector, 18" MINIMUM space between reflector and top of canopy, and about 3.5" for bottom of tub and medium. That's 29.5", leaving me only 18.5" for the plants from the top of the medium to the top of the canopy. I don't know if that's enough room for my strain yet.

Does anyone ever top a SOG to keep height under control? SOGgers seem to think that's a no-no but it makes sense to me - if your girls are too tall after the 2 week stretch, whack 'em before flower development is significant but after most veg is over.

But the doubt has me wondering about a SOG-SCROG, combining the small plant size and low veg times of SOG with the training of a SCROG. Anyone ever run something like that? Speaking of doubts, using a screen with such a low-profile system sounds like a real pain in the ass too.

I really want to go to 0-7 days veg to free up more of my lights for flower, so I'm going to have to go with a SOG-like grow. I started flowering all my girls in veg (except my mums and clones of course), so I have to work something out, hehe.

I suppose my best bet is to slam the clones into flower as soon as they're well rooted and hope for the best. 4 PSF is tight enough to fill out with 0 veg time, right? As for strain, I have two, Neb and a very bushy Indica dominant unknown strain, super tight nodes on that strain. I guess I'll top them during stretch if they get too tall.
