Pulling 4oz off 1 plant ?

if you could sum all this up in a good answer ( i know i'll catch shit) it seems as though the best yields are coming from plants in larger containers ... bigger root zone = bigger plants = bigger yields..
to add to that would be a perfect room/co2 and alot of light.

the more room the roots have to grow, the bigger the plant. (there are always hereditary things that effect this as well)

I used two gallons and three gallons but always all three or all two in one room at one time-I never mixed two and three gallons in one room. I always ranged from 3-4.5 Oz a plant with this set up.
Was there a big difference in yield between using the 2 gallon vs 3 gallon pots?

I wonder how much of a factor this really is for hydro especially. I have grown in 4x4x2" AND 4x4x4" (twice as big) RW cubes side by side and the plants were exactly the same. So although I doubled my grow media, the plants so no difference in a flood and drain.

Well I can't speak to rockwool, don't touch the stuff, but in soil it makes a HUGE difference. I run 5 gallon+, and I"m thinking about going bigger.

Hi,
The two v. three gallon is a really big controversy and that holds true for those commercial growers. I find, that most people on these forums grow for fun or personal and for friends. In most cases, and again I have two friends who each own their grow shops and they sell to large set ups; they both agree that two gallon is point blank the most bought. Then you get people coming into the grow shops thinking they know best, or always tryng to make it' like they have it right or dialed in. The GOOD news is that they generally agree on these two basic things; 1) two gallons are great since you can get six to nine plants a light. If you can average 3OZ a plant you can get over 1.5lb a bulb. Second, some people switch over in three gallon pots for summer time since plants tend to intake more water generally but even more in the summer time for several obv. reasons. A good rule of thumb amongst use growers in BC, Canada is that, get an OZ for every gallon you use. But thats just being the basics. I can get 4oz or close to, every time, with just two gallon pot. BUT thats not with every strain.
Bigger roots, equal bigger plant, thats right, but theirs a point when that rule is not applicable. That's an argument thats not happening on this forum. But here is a point to make about that; you can do better with 6 plants under a 1000HPS in 2 gallon pots than what you can with plants in 3 gallons that grow all branchy- train if you want, I mean, I help lead the lower growth, but I also train the top of the plant with the light. Big thing is, maybe you can't grow with two gallon pots but always had good growth with three gallons- than that's what works for you and the grow environment. But try to realize were people might be coming, some do this for fun or a living.
I find two gallons rock, they are a place just to hold roots, no live soil etc. I control what they eat. I also want my pots packed-root bound before flower. I always dont want to veg for 4-5 weeks. If you go bigger pots, means more veg time. If you dont veg long, you will just get a weaker root system that sits in a larger amount of soil that tends to never dry out. So if you go bigger pots, have to veg longer, but than you get more plant that does not get much light! But, again, this is one view vs. many other self acclaimed guru growers!

Pot size doesn't increase yield, it can only decrease it. Once a plant is in a container where it won't encounter any restriction to root growth, it will grow to it's normal maximum size (max for all other growing variables). No amount of extra pot size will cause it to grow bigger. The only question is whether or not the roots become restricted by the end of flowering and if so, how much.

The other thing we want to mention is that, in our experience, cannabis roots tend to grow more downward than outward. When different shapes of containers are considered, you can't say any specific volume is perfect for a given plant. Pots having equal height and diameter don't last quite as long as some pots that are slightly taller than they are wide, even if they are each the same volume. Quite often, roots will have more time to grow when taller pots of the same diameter are used. The grower can flower for longer with fewer problems and the new pots don't take up any extra floor space.

This is very true, and a good way of looking at it. The one caveat I'd throw in there pertaining to the issue of container width/depth ratio is that it's true for most containers, but I think the new "smart pots" and their ilk are the exception to that rule.

So are you saying that when I root bound my plants in two gallons and get my 3-4oz a plant is generally is true- lets say' and that when I increase my pot size-three gallon and root bound my plants my yield will not go up? I see your point in reaching whats called' plant potential' but the way the info is stated is skewed largely to fit this thread. What your saying would hold true outside, not inside, since we are always holding our plants back either with one thing or another! I guess an interesting argument would be against those growing in a vertical system, or those who believe more dirt volume is better; that is, they do use larger containers such as 5 gallons. In this case their yield would increase.

I do agree with the 'weather or not the roots become restricted by the end of flowering and if so, how much'. But I would not read any more from that book. It does not sound very applicable since no matter what pot you use inside, you will restrict your root growth; in turn, yield. I am a little confused on' normal maximum size' are you saying you can get larger than the max size but that would be rare to happen? And another confusion is how larger pot size decrease yield. I want to hear more about it, not to mock, but to hear you out, and it could be interesting. But what about those organic growers? They grow larger plants in large pots to help increase their yields; yes it is also for holding a larger, rich food supple, but also holding a larger root structure.

In all seriousness, the 5 gallon pot is the only true pot that is equal, the rest is off in proportion.

No, he's not saying that increasing the pot size won't increase your yield. He's saying that pot size should be thought of as a limiting factor in potential plant size, not necessarily that bigger pot= bigger yield. It's true. If you are reaching your plant's peak genetic potential in 2 gallons, then you would not see any more yield by going to a three gallon. I doubt that would be the case, as most plants are capable of yielding far more than four ounces under ideal conditions.

Edit: after re-reading my post, it comes off a bit scattershot, basically the pot is almost always the limiting factor indoors. I just smoked a nice blueberry joint, so I'm not fixing my post because it'll probably only get worse. Oh well.

Root size and condition determines every other factor in plant growth...but I guess DWC and aero guys are wrong about more root surface area...right?

I have a friend who grows hydro like a dick (he doesn't do it well...) and still pulls 5 oz per plant under 1 1000w light 4 plants per light.

thanks for the input guys. So if i do an aero setup it should be no problem pulling 4oz a plant with a good light and co2. good to hear.
It depends on plant density, veg time, your skill, etc.. If you run between 9-12 plants under 1-1kw HPS with about a month of veg, you should be able to pull 1-2lbs depending on strain and the factors I listed previously. I usually get around 2, and that's in dirt.

ebb&grow system with 30 day veg would put out with the right strain around 6 ounces per plant
The thing people keep leaving out of this equation is planting density. 6oz per plant is great, but is that with four plants under 1kw or is it with 12 plants? There's a big difference there.
