What Size Net Pots Do You Use?

Just as the title says, what size net pots do you use? I see a lot of people using rather big net pots in DWC, and I don't get it. Is there any reason to use 6"+ net pots in DWC? Bigger pots just means more hydroton, the plants get their nutrients from the water anyway. I was planning on using 4" net pots. Am I missing something, are 4" too small for large robust plants even in a DWC or am I on the right track here?

I prefer 3.75" net pots but right now I have all these dang bucket lids to use up lol

I honestly think its just because of the bucket lids that are available and fit so well. I use a swc type system that the plant is in a 2" net cup, even the biggest heaviest plant i have ever grown has never had a stalk that was bigger than 2".

I use 5.5''.. I cut a hole in my sport cooler lids to fit a 5.5'' hold so I'm stuck using 5'' -6'' ..

I just use 5".yeah I don't get the whole 8"+ netpot and whole bag of hydroton thing either..

i used the 10in ones. a pain in the ass after harvest lol when u have to rip n tear to get ur hydroton back. lol im buying new hydroton. Huge root ball tho

5" are good thats what i roll with!
