its blue dream i've ran the strain a few times and it yields better then the other strains i have, pretty good size plants Im just wondering what everyones experience is with this amount of plants under 600w yield wise? the chinese sunnyx or whatever leds i got didn't nearly produce what i wanted for 8 plants. they drawed about 250 from the wall and there cree's. thanks
 
I'm going to assume you'll get the answer of .5 p/w to 1.0 p/w from nearly everyone regardless # of plants. Which kind of goes off my train of thought that you'd be getting one main cola's on each plant ranging from half zip to a zip and a half per plant pending light penetration of the perimeter plants.

What soil, nutes, veg time are you using btw?

i got 6 oz from harvesting the 8 plants, im using promix with mychrozia or however you spell it, general organics nutes, and veg time is 4 weeks.
 
How big are your containers? I find 8 plants are my limit, and I'm using 2 600w hps's I usually just run 6 plants. If you keep em small and don't top them you should be ok. I pull about 3-5 oz a plant in 5gal ebb&flow buckets.
 
The LED you were using is absolute garbage. A proper cob setup would have given you better results.

As far as plants under a 6, it depends on container size and spacing. You'd ideally want a 6 to cover about a 4x4 area, but could get away with going slightly bigger. A friend of mine runs a 6 in a 5x5 - he likes the extra room to work, and the tent fits a 4x4 tray nicely. He runs 9 girls in that tent.

I use 7 gal bags how would 8 per 600w hps sound?

yeah i bought them because i heard that cree leds were good but im pretty sure my 5w epistar leds did better then these

How big an area?
How much head room?

Lets see, for an example. 4x4 space - 1 gallon nursery pots = 49 plants. SOG by flipping to bloom at 8 inch's and strain dependent. You should get just over a zip per plant..... say 32 gr per, for the sake of math. 56 zips at 2.6 gpw is the result for your 600.

Use normal 30 day feeding soil, and trans the popped bean directly into the 1 gallon pot. No topping - flip the light to bloom at 8 inch's. Begin feeding nutrient at the flip.

See what I'm getting at. If your not limited by #'s.....SOG is great for small area's!
 
4 weeks veg = 3oz3.5oz per plant for me. But i couldn't fit 12 under a 600w hps. Couldn't even fit 7. not in the right space so they all get enough lighting.

@Dr. Who have you seen anyone pull those numbers you said from SOG? I was under the impression 10gram from SOG with 4 per square foot was good, so an oz per plant with 49 plants seems very high, especially when you look at the GPW, that's not close to most of the evidence.
 
If you are already in 7gal bags and the plants are big (how big?) then you may already be limited to 4. I don't think you are filling those bags anywhere near in 4 weeks though, unless I've misread something.

What you can also try, if you have the space is 8. Put four on the floor covering 4x4 space with light covering that print (if the bags/canopy allow it 3x3 would be better) then at either side but two pots raised up on wood/containers by about 1f (depends on plant size, give or take). Those on the outside edge will get good side lighting especially if on 3x3, like a make shift stadium setup. It works well, if you have space. The side ones ofc won't yield as much as the central plants but as an estimate, maybe 1/2 to 3/4 max of what you get from the main ones. It does require open hood and canopy temp control though. If you are open hood you can try to drop your filter down online to the end of the bulb (filter sleeve facing the bulb) so that it can suck hot air directly off canopy.

I've done it myself Corey. SOG does not mean you run 12/12 from seed either (seams like that's what you think)

I've done far better GPW with a 2x2 and a 400w......that's not the point.

A 1 gal nursery pot is 6.5 inch's across (There is a pot brand that will fit 64 pots in a 4x4 - that's cramming them in!). You can fit 49 in a 4x4. You set the light height for the light to cover the area at 18 - 20 inch's over the pot surface - you must use a square hood for a square area.

When the plants in the pot reach 8 - 10 inch's from the media surface - you flip to bloom. They will dbl in size by height. You will have a limited amount of side branching. Trimming is up to you but, I didn't on the example run.

I've seen a SOG that would blow your mind......Sadly it didn't last long before Police intervention......They recycled the soil every run and it was set up at waist high - ease of work. All automated too. Fill tanks and walk away - days, weeks at a time.....being soil, they would look at it once every 5 days......I had a hard time wrapping my head around that alone!
 
That's some cracking figures @Dr. Who, very nice indeed.
No I gathered it would be from clone.
Its been a long time since I looked into SOG, it was one of my first options I considered, but the plant count is what put me off, Johnny law man coming round ect. Closest I have done to a SOG was 1 per square foot, which I don't consider a real SOG at all. Even though I have met people who do think it is. I suppose its like ScrOG, the idea gets watered down over time and the terms get banded around willy nilly.
I do remember seeing some impressive SOG years back in high times, everyone was wanting to do it then. Don't see it as much these days, or maybe I just don't look in the right places.
Anyway very impressive!

well the blue dreams are about 3 feet maybe a little over once stretch is done. they get pretty big in veg i could even do 3 weeks and they would still be pretty big. and no i definitly dont fill the bags at all, but i dont have to water them for a couple weeks after a watering, or about a week toward the end of flower. There is 4 in a row two rows directly next to each other. they dont all get equal light but at least the light covers all of them at about two feet above maybe less.

If they are finishing 3 tall, healthy and not stretched (do you have a pic?) then you should consider topping next time to keep them shorter, even out the canopy and yield more. I've seen some things on deep pots promoting taller plants, rather than wider pots. So I'm interested if you have pics, as it could confirm that burying plants deeper on transplant is actually limiting.

Your watering schedule sounds iffy to me. I don't know how well it does in organics but the bottom 10/20% of your bag is surely a breading ground for nasty shit. Do you check the roots immediately after chop?. The lack of dry cycle by all accounts will lead to troubled root development/health and hold back yields. But, maybe your roots are shooting down and filling some of the bottom before that happens?.

Btw 2 feet above is too far. For 600hps 18" is about as far as you want to get before density suffers (particularly mid/lower bud) bare in mind 18" from center canopy will bowl out to about 22"+ on canopy edge. Are you vegging from comparable distances?.
