How Many Plants Can One 1,000 Watt HID Light Handle?

if you have pictures to prove me wrong please do, because i would like to see this

150w for the first plant and 50w for each additional. should be about 18 plants. i usually divide that in half for my grows so in my opinion 9 plants per 1000w.

You do know there are 24 hours in a day right? Tell me why you think think I'm wrong?

dude i dont care what you say. anything over 2 grams per watt is almost unheard of no matter what kind of setup you have. a light can only do so much

Well I'm happy to tell you there is a much larger MJ growing population beyond RUI, or any forum for that matter. This obviously is not a traditional method of growing, as any sane person would buy extra lights for increased yield, but it isn't impossible. You don't need pictures to "prove" something wrong or right, although it helps if you can't understand something, especially on the internet.

To answer your question C Moore, the amount of plants a 1000 watt light can handle is only limited to the useable footprint of your light, and the size you choose to flower your plants at. If you want the most (and fastest) yield from using all 24 seeds at once with one light, your idea of 12/12 from seed is right when used in a SOG. You could separate your grow space into 2 areas. Each area has one superponics system in it. Your light will be on 24 hours a day, but every 12 hours your light moves to the other area. While one group of plants is in their dark period, your others are getting their 12 hours of light.

Your going to need smaller plants so they won't outgrow the small footprint of the 16 site system, and a light mover that works on a set timer over a longer period of time, instead of one that moves slowly every few minutes. Your also going to need to trim the lower branches off your plants to keep them this close together in the superponics system. A custom horizontal cabinet that prevents light leaks into each area would work best with what I've described.

Although you can grow all 24 at once, if your really strapped for space, a scrog might be a better choice with a smaller amount of plants, reaching a similar yield over a longer period of time (a few extra weeks for vegging)

Check out some of the vertical grows. With a 12/12 schedule you can easily DOUBLE that yield with a light mover switching location every 12 hours. Obviously you would need twice as much space.

Grams per watt isn't a very accurate method of measurements because you could cram 5000 plants (on the walls and floor) in a 50'x10'x10' space with ONE 1000 watt light and a light mover. If each plant only yielded 5 grams, thats a whopping 25 grams per watt. (Of shitty bud)

Exactly, I don't see why more growers with only 1 light on a 12/12 sched from seed don't do this. Yes 12 hours a day extra on the electric bill and the extra space might be an issue, but doubling your yield in the SAME amount of days is possible.

There are ton's of growers flying under the electric companies radar by having super high plant counts and small size, but this is usually for commercial growers who aren't as concerned with quality

In what are you basing the statement that the quality of the bud wont be as good?,

if you keep the 1ft rule you can easily fit 24 plants under the foot print of a 600W (4ft x 4ft) given a flat canopy, if you go vertical and take advantage of the 3D dispersal of the light the optimun canopy quadruples. You can easily fit 12 plants in (3 rows of 4 plant sites) on each wall and still have room to veg for 2 weeks. Flooded tubes is as easy, ecological and cheap as it gets btw!

I'm kind of in a rush with my harvest primarily because of the electricity bill, plus I'm a newbie and I'm afraid that 12/12 from seed will cause my LSD plants 2 become hermies, can this happen?

light leaks are the major cause of hermies

The LSD says 600 grams per M2.. Does anyone know if I could yield 1 oz per plant, if I choose 2 go 12/12 from seed?

Well if it helps you figure it out. I am running with a 400 w and I am getting around 3/4 of an oz per plant. And there is still room for improvement.
I think I zip per plant under your mini sun is almost underestimating what you have.

Btw I am running 7 to 9 plants in a 4X4 tent, All vegged until 1 1/2 ft.

No way did you get over 4000 grams with 1000w. Without pictures cant believe that. C Moore if I were you i would grow sog. If you don't grow sog and you grow your plants out definately top them to get 2 or 4 main colas. There are threads that teach you how to do this here on RIU. It kinda sounds like you might be biting off a little more than you can chew but hey prove me wrong. Good Luck.

Dude, you can't go 12/12 from seed. And getting an oz per plant depends on what method of growing you are doing ex. sog vs natural or topped plants.

I don't think 4kg is realistic but in vertical 2GPW should be easily achieved.

12/12 from seed will cause unnecessary stress to your plant. yeild and quality will greatly suffer. ive tried 12/12 from seed and ive also done 3 weeks veg with the same strain. my yeild almost tripled, and the potency was better as well, and they both fineshed in about the same amount of time. i dont understand the point of 12/12 from seed when it takes 3 to 4 weeks for the plant to show sex any way. like i said same strain veged for 3 weeks triple the yeild and it only took maybe a week longer than my 12/12 from seed.

That's some good info from someone who has tried both methods which makes me 2nd guess 12/12 from seed since it's almost the same amount of time 2 harvest but greater yield and potency!..

But I may veg for only about 2 weeks considering that I'm using only one 1,000 watt light for growing 20 plants..

Sorry I didn't read it was from seed.. Dude don't do that!!

http://www.youtube.com/watch?v=PQ9tmm2ljVw&feature=related <--somewhat what you should expect if you have some growing experience under your belt. though i have no proof that this dudes video is real, the way the buds form on the plant it seems legit to me.

right now im trying a mass 12/12 from seed lst grow, and they are pretty fuckin big man, and im sure they are going to be just as potent if i would have vegged them for a couple weeks. but this is my first time.. we will see. (a couple i vegged for 3 weeks, a couple are auto dwarfs

if you dont have tons of room, you want to bring your electric down, want to harvest a month earlier than usual? start from 12/12. nah bro you wont get hardly as much, but im sure reasonably speaking that the buds will be just as potent... not sure why someone said it would be less, im sure if you harvest at peak maturity it makes no difference, but i have yet to experiment with this so i really dont know. do what fits your needs, but also do what fits your plants needs. you cant grow awesome pot when you dont water because you want to go out and party, its gotta be a passion, its a contstant game of expermental techniques. growing not only your plants, but your mind aswell. you get out of it what you put in it, no matter who you are or what type of grower. you spend 4+ hours in the garden every day it shows, as you can see.

you can grow as many plants as you can fit under a 1000watt hps, just know that the plants furthest away from the light arent going to yeild as much as the plants closest.

a cheap way to utilize more light would be to buy some mylar and tape/glue/tack to cardboard or thin wood and set it around your grow area to reflect all that light that isnt being used.

That's impresive, definately the best, or at least most plants that I have seen done with 12/12. Let's wait and see how it goes. Ill be interested in if you have a lot of hermies. Are those fem seeds?
