for drain to waste growing..
ps roots breath too .. thats why u pump in the o2 into the water tank in hydroponics operations
..What about a plastic pot inside a fabric pot..?
why would u put a plastic pot inside a fabric pot ? the plastic blocks the air flow not a good idea
The roots get air pruned at the edges of the fabric container,
much like they do when they get to the bottom of a plastic one - unless they're sitting in water of course.
The roots not circling helps avoid them becoming root bound.
That in turn means you can grow larger plants in smaller containers, and there's of course less need for transplanting.
Seems perfect for keeping mother plants for example...
Anyway I don't want to derail the topic here. Perhaps we could debate this in another thread.

Accidentally hit reply, CL
We’re talking about pot sizes growing in coco to run off?
OK.
My opinion is everyone uses too big a pots in hydro/coco
Had a load of rockwool 15x15cm (6x6”) about 3 litres, 0.75 gallon delivered today.
The 3 litre solo cups bag 200g plus out of you nail it. Roots all around the edge like Wastei showed.
Sure our 5 gallon airpots go bigger but not everyone has a dedicated room with 3 metre high ceilings.
The problem with the fabric ones for me is the lack of support. They’re cheap and get the job done but the medium falls over and sinks and then the plant does too.
Rockwool though - its what I see 90% the commercial guys using in the US
So this grow we’ll give it a whirl.
Our @Canuk Seeds Gorilla Bruce are still in half gallon plastic pots. Good metre high. They’re in reveg, back on 18/6 stress testing them. Excuse the yellow - back on veg nutes but skipped watering on Saturday!

Flood tables with rockwool is a winning concept! So easy to operate and the results speak for themselves, and less to no need for Calmag Nick!

Ok Wastei I gotta ask, how come you don’t need c-m in Rockwool? CLFlood tables with rockwool is a winning concept! So easy to operate and the results speak for themselves, and less to no need for Calmag Nick!
. 
Wait what?!Flood tables with rockwool is a winning concept! So easy to operate and the results speak for themselves, and less to no need for Calmag Nick!
No Cal-Mag?! Heresy!
@Bill284 was saying the preferred Ph range changes?
I think we missed using them this grow - the holes are say 5cm diameter - ours are already in solos so the root balls too big?
I have a solo cup sized (90mm) cutter though?
I'm wondering if he means pre buffering with it - we don't do that because our coco comes pre buffered but they still want Calcium, right?Ok Wastei I gotta ask, how come you don’t need c-m in Rockwool? CL
You better asked the question than me!

With a complete plant food in a complete inert medium like rockwool it's often not needed. In water cultures like DWC, flood tables etc "Calmag" is solely used as a pH up buffer and there's better more stable buffers for that purpose like potassium silicate or bicarbonate.Ok Wastei I gotta ask, how come you don’t need c-m in Rockwool? CL
In coir and peat it has its place since the medium holds on to the added mineral buffers which help maintaining the mineral ratio of the base of the plant food. Calmag is only detrimental if added when not needed. It's all about mineral ratios and how we better keep those in check.
OK, huh maybe.
OK - but the calcium demand is fulfilled by their A/B in an inert media? I buy Hydro/Coco RO Dutch Pro Veg and Bloom and their Cal Mag is one of the only things not available in 20 litre (5 Gallon Cans) here because they just assume - yeah you won't need it?
Their Cal-Mag btw is 5-0-0 + Fe. Sounds fierce!
Does that make sense Wastei? Am I understanding correctly?
That implies I just follow the Dutch Pro PH 5.8-6.0 guidance still even though rockwool? tyvm in advance.
Cheers!

Yes that is 100% correct. Calmag didn't use to be a thing back in the day. It took Canna many years before they gave in and released a Calmag product. When I started growing many nutrient manufacturers hadn't started selling any Calmag products yet.
Traditional two part formulas was carried over from the tomato industry and they typically have high amounts of Ca and Mg already in the mix.
Cheers!
