why not 1 plant per light

im starting a room running (6)600w.im gonna do 1 plant per light.with everything i have been reading i should get the same yield is when i was doing 3 plants per light.any opinions on why i should do more than 1 plant per light.thank you.

I would think running 600w, you could put 2, maybe 3 per light and still be effective, as long as you were careful about the placement..

Let me put it this way;
If you had a 5x5 space and one 600W light with 25 plants in there, 1 plant per sq ft, or say 4-5 plants, one for every 4 or 5 sq feet. It would yield just as much as if you were to do one plant, quality genetics, scrog, good training in veg, utilizing LST, FIM, topping, supercropping, you want to get a really nice canopy for flower. Scrog it out and I guarantee that plant will fill the screen. However you could do a few plants in there if you wanted more than one strain, but it would still be approximately the same yield. So in a 5x5 canopy scrogging one plant vs 2 or 3 or 4 or 5 or so on, would be about the same yield. If you were to increase your sq ft you could get more buds.


This guy explains it pretty well;

What you described is pretty much dead on my current grow, 5X5 w/8' ceiling, 600W with a bit of CFL, I got 4 plants in flower. Chech out the later pics in the link in my sig. I trained these down hard all through veg. These 4 fill up my 5'X5' flower space completely.

You should put as many plants as will fill up the usable spectrums of light provided by your lamps. If you put one plant, you may have a lot of space where light is hitting the ground. It doesn't somehow circulate back up to the plant's leaves - it just hits the ground and warms it up. I'd ASSume that you could put 2-3 plants under each 600w hps - I think the light penetration is at 2-3 feet - I would put at least two under each.

Something to think about; At first it wont cover the whole space but eventually after alot of training and utilizing the scrog you can easily have it fill up. If you watched the video I posted that guy has a 5x5 canopy on a plant that is 6 inches tall, he doesn't even have a screen on it either.

A remedy for this would be having two veg rooms, one small closet type space where you put a bunch of different seedlings, the other where you choose one of those seedlings to grow out and maybe a space for some outside. You could have the seedlings under a t5, that way they wont grow too fast, when one has about 6 or 7 nodes you just take it in to be trained, and plant each seedling about 5 days to two weeks apart. SO for example;
a 2x4x5 tent with 5 seedlings, each seedling/clone rooted/planted 2 weeks before the other. You take the oldest best looking clone, train it out for 3 weeks in a 5x5 veg tent, in this time you can switch THAT clone to flower in a large 10x10 tent in the corner and give it a 5x5 screen for flower. After three weeks of veg, the previous clone that was rooted two weeks before the one you threw in flower, is now ready to be trained into a 5x5 canopy that is 10 inches tall or so for 3 weeks, then you put that in flower, the next one is ready and so on. You just take a clone or two before switching each one to flower and you have got yourself a perpetual harvest with probably about 1lb or more per plant if you know what you are doing.

Will definitely be checking out your grow man, I have a girl scout cookie original thin mint pheno journal up as well as AKR and boss hogg going right now, Girl scout is straight from norcal ;) Clone only.
 
It's the easiest way to grow... You just have one big plant (per light)

The more plants the more hassle.

However if your breeding, that can work against you. In that situation, numbers count. And having more plants will work in your favor.

What someone said above, the only real difference is veg time. 5 x 5 with a 600 though...mmmm not really gaining anything past 4 x4. Unless you like popcorn 5 x 5 is the land of 1 k bulbs my friend. I am rocking 1 plant per 600 right now. 12 lights total. Even with a very nice hood (blockbuster) the lux falls off really quickly. If I am at 70k in the center, by the time I'm at the edge of the 3.5' screen it's like 20-30 (which is veg strength)

I'm betting a 4 x 4 plant and a 5 x5 would produce about the same.

Cheers

Well if you are using mylar or panda film you have some light reflection for better intensity there, however if its really a problem you could easily add one of those 125W cfls on all the edges.

Few of these , minus the over priced reflector.

CFLs are for dipshits dude. My horizontal room is fully panda film lined; I'm telling you, 5x5 is a pipe dream but hey, it's a free country, give it a whirl

Cfl's in an HPS room are like turn signals on a dragster
