1000W HPS - How many plants per light?

Everybody has their own way and in the end it comes to what works best for you, but I have read that most of the people use 6-9 plants per 1000W, while in the other hand other people like to have more smaller plants, hence the sog and scrog method.

For example, SeeMoreBuds had about 50-100 plants per 2000W. He was using an Aquamist system and he vegged for 25 days = 4 pounds in total of 80 days.

Just few days ago I was told by a reputable grower that I should have 6-9 plants per 1000W, because SOG method was designed for 400-600W.

He even made some quick calculations and told me that if with 9 plants per 1000W I would get 36 ounces, then with 16 plants I would get 32 ounces.

I was basically asking if it's okay to have 16 plants per 1000W, because I figured 16 plants will yield more than 9 plants in 90 days from seed, but he was sure as hell that 16 plants is a bad idea. He even said that it's just lighting up plastic as the light will shine on the soil.

For the last thing he said that "for the love of god, please choose 400-600W, if you want to do SOG".

So now I'm confused, because I paid a lot of money for my seeds and it would suck if I could not use them all.

Can someone please explain me why is it a bad idea to have 16 plants per 1000W per 5x5 feet area and veg them for 25 days?

I thought it's a fantastic idea...

25 days from seed and 25 days from rooted cutting are two completely different things. the important thing is your 5x5. pack em in there if they fit, cull if they don't. next time you'll have a better idea of how to do what with what. i think i had 56 under a 1k with 2-3' in total height.

Are they all the same strain? Fem. seed?

no problem. get some pics up if/when you can. seeing the situation might help with more advice.

dont see anything wrong with it. just need to use smaller containers....the amount of plants doesent matter as much as the square footage of the area your trying to light. if you can fit 16 plants in a 5x5 room and have good light coverage on all of them then you should be fine.

his calculations on yeild are just jibber...no one can say for sure how much yeild you will get...they cant account for genetic variables. they can say what system and methods are more optimum.

i have a 6x4 flower room with a 1k in it and could fit about 8 plants in it 2x4 the room became overgrown fast and left alot of plant in the shade. if i ever grow again in that room i will make a 4x4 Scrog and do 4 plants i think this will ultimatly give me a much better yeild and light distribution.

as far as not using the seeds..they keep well in a cool dry place..use some for the next grow. if i had a 5x5 with a 1k i would build a screen and do a massive ScROG...great yeilds and easy trimming (i have scrogged before and came out pretty good)

as far as what you can and cant do thats entirely up to you, 1/2 the fun in this hobby is experimentation. give 16 plants a try and you will soon find out if it was a good or bad idea, then you will gain knowledge that will make your next grow that much more successfull.

a tip to the wise, if you spent alot of money on seeds and this is you first grow...try a couple plants first to work the bugs out of your system...then use them all...would be a shame to plant them all and have something go wrong and lose you entire bank of genetics (new growers lose thier first crops all the time) i have seen first time growers lose thier first bank of seeds just trying to germinate them lol

Didn't we already address this same thing ?

Thats just about the right amount of light for you room but to many plants. The golden rule is 100w a plant so 10 but even 10 in your room will be to many. Sog yes stick as many in there you can fit.

5x5 room if grown normally 6 plants.

In my opinion the most important question is: How much plant surface is there under the light to make photo synthesis and convert that light into yields.

So... honestly... don't you think that bigger number of plants would cover the SAME amount of area IN LESS TIME than smaller number of plants?

In other words: Don't you think that if there is 6 plants vs 16 plants, then 16 plants would cover that area with green MORE QUICKLY? ---------> Hence the more plant surface IN LESS TIME? ---------> Hence the same amount of results IN LESS TIME?

Please tell me... am I missing something?

P.S. Sure, more plants mean more work, but I'm not asking how to make less work. I am asking, which way is faster for the same amount of results.

I go with two but big,dep on how much height you have,and a a light mover

Do it, it will work great. You have already asked several times, you obviously didnt get the answer you wanted so im with ya, grow 25 plants from seed in a 5x5 under 1000 watts, you should get 2 lbs easy, just like the guys who do bare bulb vert stadium hydro grows with 50 identical rooted clones that dont branch much around a 1000 watt bulb. There, I agreed with ya, do post pics before ya flip, should be entertaining

Really..... I mean, this guy created this same thread last week and the thing is, he was given some especially good advice by some guys that really know their shit.

I sense sarcasm.

Yes, I know I was given advice, but I was given no explanation. Opinions are like assholes. Everyone has got one and everyone thinks everyone else's stinks.

Why should I take his opinion as truth? Because he has 9000 posts and got his name written with marijuana on his display picture?

I am just trying to discuss openly. What use do I get from your opinions, if you don't explain yourself?

What is the value of your statement if you are not able to prove it?

What is wrong about a discussion?

I told you to look into the inverse square law of light penetration.


I didn't say that SOG wouldn't work.

I merely said that it would be a waste of light to run a SOG 1000w setup.


How about you do what most of us do and research or try it for yourself.


Find me any large scale grower that uses 4k of lights and runs a SOG setup.

Go with your 16 plants, follow your gut.

What's the worse that could happen?

You might have to chop a few if your area becomes overgrown.

Up-date with pics, with what you decided to do.

My gut right now says to plant 9 plants per 1000W in a hope of having a better chance for guidance. The result of this grow is going to have an utmost of importance for me, so I figured it's not the best time for experimentation.

Thank you for the help. I appreciate it.

SoG works awesome under 1kW lights. I know, I've done it. With SoG you can get gram per watt yields with little to no veg using 4x4 area with 7x7 grid of plants for each light.

It seems like this discussion did not end yet (hopefully).

But it doesn't change the fact that I'll go for 9 plants per 1000W.

I just hope it won't take longer than 6 weeks from seed until I can start flowering.

That way I would harvest by the end of May, which is what I need.

more plants = less veg time for same yield. Also almost all nug is tops, you lolipop the sides and its a tray of popsickles.

I like 6" square pots on a 4x8 (inside) tray. Unlike rockwool logs you can rearrange them by height (stadium) for first three weeks, then lollipop and trellis.
