jronn, there's a difference between growing hydro in a pot, which is DWC, and flood and drain tables which is what is shown in those pics. You asked about growing in a pot and were told 5 gallons minimum, which is typical. flood and drain tables provide more oxygen to the roots after draining.
Im lost on your comment. if you're talking about the old pic i posted i dont have them set up that way anymore. now i do top feed drip and use a flood tray to catch the water and drain it back in the res

i dont know if this helps answer your question but

typically,

the smaller the root area/medium the more frequently youll need to water

the larger the root area/medium the less frequently youll need to water

im personally not a fan of grow rock because they hold very little moisture and if the pump fails you lose your crops
but that was partly cuz i needed to leave my plants un attended for several days at a time

when i grew hydro i chose to grow in rockwool because it held some moisture

if i grew my plants in a 6" block i would need to water less frequent
if i grew in a 4" block water more frequent

but either way my yield was the same

I don't know that I can answer your question as you have asked it but maybe I can help you sort out the answers for yourself

when speaking in terms of increased yield id say the largest factor other than genetics is light
more light equals more yield up to a point...but more light also equals more heat control issues

as far as plant spacing.. you can fit as few or as many plants into a space as you want...
fewer plants equals more veg time to fill the space

for example
1000 watts of a 4x4 area
16 plants in a 4x4 area might only veg 1 week, maybe less
4 plants in a 4x4 area might veg 4 weeks

both will yield the same

i wouldn't want to transplant hydroton if i could help it

you could grow a plant in the 7" pot thatll fill a 2ftx 2ft area
but if your able to use a slightly large pot do it, theres no harm that's for sure

im not sure i got a full picture of your set up.. im wondering though would you be better off with net pots?

is this aero or flood and drain, or a top drip set up?... im just not getting a clear picture
yeah i get what youre saying, i guess what im asking is given that i use hydroton doing continuous top feed drip and im trying to fill 2.25 sq ft of canopy per plant.... will there be a difference in bud size/yield if i use a 7in pot for the whole cycle compared to the 9in pot? obv granted theyre both vegged/flipped at the same size

ok so that best described as

a recirculating drip system

with the hydroton i just feed nonstop when the lights are on and im there every day and im not worried about a failing pump im home everyday and will know somethings wrong when i dont hear the splashing lol but okay i get what youre saying so youre basically saying you can have a smaller container/pot, you just need to water more often to make up for it and the yield will ultimately end up the same.

when i first started many moons ago
i grew in ebb n flow rocks

switched to top drip rock

didn't like the top feed in rocks.. the roots always grew un evenly the moisture didn't soak the entire area evenly

so i switched to rockwool, i grew it for years but its a pain to discretely dispose of the cost adds up

im not sure youd need or want to water continuously

i would think a couple minutes every hour would be plenty

itll just depend on the size of the plant vs the size of the pot

EC vs. PPM depends on what scale you are using. to some scales, 1.2 ec is pretty high. it's better to use ppm instead of ec.
Incorrect. EC is universal. Ppm is a derivative of EC with two different scales, 500 and 700, which is why when someone says ppm they need to include which scale they measured with.
1.0 EC on the 500 scale is 500ppm.
1.0 EC on the 700 scale is 700ppm.

i use the r/o version and my tap is so low it doest measure on my ppm pen.... im going to start trying to use their foliar supplement instead of using calmag. but some people are most certainly using 6" rockwool and growing big plants, you ever heard of the jungle boyz? theyre known for being one the best growers in the country and they using a 6" cube from start to finish.
Monster plant to me is like a outdoor beast.

having said that i used drip stakes

if you use one of those rings you might get better results than i did

i just started using floraflex dripper caps, theyre made to fit rockwool cubes but their 6" model fits the 7" square pots perfect and their 8" fits the 9" pot perfect. i have 2 tubes to each cap looks like the pic i posted they create a pretty even watering... i started doing continuous because i was doing a sog with 5" netcups and i started with 5 15min drips per day then i kept upping it till i realized they loved the continuous drip and now that you tell me the smaller the pot the more they need to be watered it makes sense... but if i can use less medium and get away with using the 7" pot and still get the same yield then it sounds illogical to use the 9" pots

if it was me and I had the space

id get the larger pot if it doesn't disrupt your space

if your trying to use the smaller pots to fit an existing space so be it yes itll be no problem

a larger pot gives you a wider area.. plants will grow wider when the root zone can extend in width
if you want you could use a wider pot and not fill it to the top

the extra width also provide more stability at the base to keep the plant from tipping over
a small pot with rocks holds very little weight compared to the top of the plant

if you where growing SOG id say use the smaller pots but your also talking about growing bigger plants and experimenting on what works for you.
a slightly larger pot might provide more options down the road

in my opinion and in my experience the way I would set up your space would be

5 plants under a 3x3 area with a 600 watts light in an 8" pot with 2 weeks veg time
(10 plants total)

its a happy medium between SOG (to many clones) and scrog( to much training)

if your plants are tall top them 1x and veg an extra week
if there short just let them be

with an 8" pot they wont be tipping over on you and possibly require no netting no staking and no training

just an option, thinking out loud

get the smallest pvc fittings the sell that has all the parts and pieces
build it into a square that fits inside the pot and just let it lay on top of the rocks

and get a hose barb fitting that's threaded on one side (to connect the pvc)and hose barb on the other (likely brass) that fits the feed tubeing

drill small holes in the pvc
youll need to play around with the hole size and how many holes compared to your pump size and how many plants to get proper pressure

personally
I would buy the cheap lowes 1/3 hp pump for $80, get one with no float switch

I like them because they last a long time and theyre easy/quick to get in the case of a pump failure

yes theyre over sized and noisie but I don't care

then when it kicks on the pressure is high and comes out of the pvc likes its a fucking areo cloner lol

I wonder if you could even install the plastic mist heads they use in the EZcloner machines and fit them into the pvc
I know the plastic tips are threaded screw into a specific hole size

how much money are those watering dish things?
the flora flex things are 4 or 5 bucks each and i already have made home made top feed drippers, i like the flora flex the best i have the irrigation itsself down and the problem is i legally cant have that many

actually I have to correct myself

I was thinking of a 4x4 area with 9 plants
my mistake

for a 3x3 area you could do 4 or maybe 5 with a short smack in the middle and veg for 2 weeks (maybe 3)

I went back and edited the previous post to reflect the correct numbers
