Maximum Yield per Plant 1000W Light?

I'm curious as to the max people are pulling from each plant under 1000W lights and how many plants per light you are doing. We have 4 lights and probably 20-30 plants. We are only pulling 1-3 ounces per plant. We are using Tiger Bloom and one other nutrient I can't name off hand right now and we are also using a Hutterite soil that is very airy. We add perlite, composted cow manure and bat guano. I'm hearing about people who are pulling 1-3lbs per plant. What are we doing wrong?

what strain? how long you veg for? got proper temps and ventillation?

we have many different strains and the yield depends on the strain. we veg for atleast a month. they are clones of clones. you can clone clones right? temps, humidity, ventilation is all very good. Co2. The works.

I take it no one here uses 1000W lights?

I'm sure plenty of people here use 1000 watt lights. But the question you are asking has literally been asked 100 times a day since before most of us were born.

The light alone does NOT determine your plants yield. There are guys out there running 400watt lights who are capable of pulling more than a newb with a 1000 watt light. Environment, nutrients, stress, strain...all of these make a huge difference. Now you said that this is all ideal, so...I would suggest experimenting with different training methods.

Are you growing single cola plants? You are vegging them for a month, so what kind of topping and/or lst are you doing? Do you have any pictures of your plants? If you were running 4kw with a perfect environment, and a good yielding strain...you should pull at least a pound per light.

You should be able to pull WAY more than 1-3 oz a plant with
1kw light and a month worth of veg time.

I think a big part of pulling pounds of plants is going with a
vertical light setup and lots of them, something like this:

x o x
o x o
x o x

Where o's are bulbs and x's are plants.

Not sure what kind of light setup you're using, but something
tells me you could definitely fine tune some aspects.

yeah my setup is running like so.

o x o
x x x
o x o

theres definitely some dead spots. but even the plants directly under the lights arent pushin more than that. its just so hard to try and figure out the exact problem when it takes so long to tell if one correction has worked or not. We are medical and we are new but we know we can push this setup to run at maximum. we just dont want to waste lots of timing finding the right way.

True, If you do (example) a DWC, and make sure plants get even amounts of lights, and pick the right nutrients and dosage for the right strain, a gram a watt should definitely be obtainable.

Ive seen so many grows where a 400 MH gest 1gr=1w minimum. You seem to have your soil\nutes tought out, so just make sure one strain doesn't overcrowd the other, and you should have real tasty buds.

ps, are you running a HPS or MH ?

Hps in flower and mh in veg. The vertical lighting is just out of the question for now but that's a great idea.

I have seen caregivers, who swear by maintaining a forest with stalks the size of my arm, those puppy's were eating at least a 1000w each, and then i know some people who swear by never putting less than 1000w on a 5x5 area, in which case your yields (which are beyond variable) would be entirely effected.

you could figure out for your own situation by dividing the amount of yield you get by your overall light, this will give Grams/watt of light

good luck, sounds like your makin out just fine as is

This is exactly right. It is all about light not about plant numbers. I get pretty much the same yield with 2 plants as I do with 4 plants under two 600 watters. Grams per watt is the only real way to measure yields in my opionion

So you're saying if I got 73.6 grams off of one plant and I divide that by my light wattage(total? which would be 4,000W) then thats what i'm getting?

Gram per watt is total harvest weight divided by wattage, not just a single plant
divided by the entire rooms lighting.

Well fuck that doesn't work for me haha, we have plants on rotation and harvest every couple weeks. It's not the whole room at once. Some plants in the flower room are a couple weeks old some are older. So that doesn't work in my case.

Well you could just keep track of how many plants you can
fit in the room, and keep records of them when they come
out and once you get to a room full you'll have the total
weight of "one harvest" and can just divide by your wattage.

What are the specs on your grow room nutes/temps/methods/addatives etc?

That is a good idea. We are using Tiger Bloom and Nora Flo or Flora Nova or something I can't recall the exact name. Temps range from 70-85F RH ranges from 40-50%. We top each branch and we don't use any additives except in the soil which I mentioned above.

There's no way in hell you're going to pull 1 pound per plant growing as many plants as you are. Those 2-3 pound huge plants are vegged for months and they're of the appropriate strain to do so, than kept under a 600-1000 watter each, most often with side lighting to boot. If you want huge increase in yields go with a nute program like the Fox Farms feeding schedule or one of your choosing. Molasses helps a lot. Yield also has a lot to do with strain and the right pheno of that strain. Most strains will get at least 100 grams per plant but some are much more difficult to get that much. It sounds as if you have 20-30 plants you're looking to get at least 5 oz from each. You can get a strain like Chronic, Big Bud, Critical and easily achieve 5 0z per plant with the right nutes don't top those strains! If you want to top and grow multiple colas Big Bang or NL#5 type strains.

As stated, you won't be getting 1kg+ yields per plant in a growspace filled with 20 plants under 1000w of lighting. You need a lot of space just to bust out one plant that yields a key, and veg it for maybe 6 weeks or more. The 1kg+ method is something I've always felt is better for outdoor growing, though I've seen it done indoors I just feel it's not as efficient in comparison to outdoor methods. 20 plants at 3oz per on average will leave you with a harvest of around 1.7kg anyway, so you're already getting the return you'd roughly get by maintaining one or two huge plants.
You didn't mention any ventilation in your grow setup either, you might want to consider that if you haven't got it already, as that's really important for a grow as large as yours.

my estimation is that youll get what you get, dude.

^ that reminded me of the cowboy in the bowling alley in the big lebowskie
