The problem in my experience with a 2 inch cup
Is that the rim is too weak to support a heavy
Plant.
If your plants dont get super heavy then your ok
Or if you support the plant with a scrog so it wont sag under pressure you would be ok too.
But remember you have to be able to at least peak at the roots
These plants where around 4 foot tall
Cant remeber how big they where when they popped through as this was a few years ago
Also no hydroton
But almost evry 2 incher in this set up fell lol
