If you have two pots, one larger than the other. Yet both receive the same amount of air per minute. You will have a higher concentration of air per pot volume in the smaller pot.

Ok look at it like this.. an analogy: 10 pepperoni per slice of pizza is greater than 10 pepperoni on an entire pizza... Assuming plants like pepperoni pizza. Lol
So a 1 gallon pot (aka smaller pot) will have a greater amount of o2 per gallon of pot volume (aka o2 density) than a 2 gallon pot (aka larger pot) when all factors you mention stay constant.

Using the single ones. Never liked the idea of the other ones that are paired in to one tray. Hand water for sure at first. Expect the modified one to get on the res and airdomes first of course. So that in itself might mean the smaller pot is going to beat (need to define what "beat" means) the bigger pot.
I don't know how this will work out timing wise. But maybe after 10 days the small pot will go on the res and air. And the large one around day 20.
Yea, density. Who cares about density per pot?
Anyhow... there is 10 pepperoni on both pizzas.
Not sure I can explain this. @slowandeasy would be better at it.
But I think the "density per pot" is important. If you have less medium to get air in to with a small pot that means that pot will get a lot more air (per cubic inches of medium) and therefore a healthier and maybe bigger plant. The bigger pot is not getting as much air to the overall root structure.
Also I think with the smaller pots and perforation the medium is going to get more air on the sides etc. And the smaller pot is maybe going to dry out faster and then drink more than the big pot will, therefore it will take in more nutes and grow bigger/better.
And one final thing. I am thinking that starting out an autopot grow in a small perforated pot will mean that I can turn on the reservoir and airdome faster. The depth of the pot is shallow compared to the full size pot. So the sooner you can turn on the air the more rapid the plant goes. Will it be bigger in the end since it started starter earlier? I don't know but will try and find out. Going to do a side by side grow with the regular pot and my modified pot. Just waiting for two Dinfem Critical 2's to pop their tap root.
You should care about air density.Yea, density. Who cares about density per pot?

Consider this... The higher the altitude the less dense the air is therefore you have a harder time breathing on mountain than opposed to sea level where the air density is high. So the same is true here with the plants... a higher air density allows the plants to breathe easier.
Also if you have say 6 slices of pizza and each slice has 10 pepperoni you have 60 pieces of pepperoni on the pizza... Not 10.
Hope this helps you grasp the concept..

I had a look at the autopots UK website and noticed they have smaller pots too. And they recommend using a pot sock to control roots and I assume prevent the roots getting in the tray and valve. It seems like its really just like a root control disk but it goes up the sides of the pot and must just stop roots that might normally shoot out the side if only a flat control disk was used. I'm thinking of making one of these for my modified small pot out of landscape fabric. It's easy. Just cut a square of fabric out bigger than the bottom of the pot, cut slits in the corners so you can fold them, and then maybe tape to the pot to hold in place. Or if you were ambitious, sew them up.

Really not that hard to understand this concept. The bigger the pot, the more medium you use. The more medium you use, the more resistance it provides to the pump. Think of it as water instead of Coco. Will one Airstone in a 5 gal bucket of water provide the same air to the roots as in a 2 gal bucket of water? No, you will need 2 airstones and 2 lines to move the water as much and provide the extra water with more Oxygen. If you put one Airstone in 10 gal of water, it may barely move the water.
