4L pot O.K for 18" plant?

I'm making my grow a lil bigger this year, last 1 was 14" final height. This year I'm going for 18 to 20 inches final height (or vegging another 2 weeks which ever comes first). Last time I used 4L pots and they were fine, I'm using the same pots and don't plan on transplanting. My question is how will the plants cope with the space, will there be any significant effect on yield

That pot size is fine for hydro?? Not familiar with what your doing though. VV

you could maybe just about get away with that,im using 7ltr pots and my plants are 24" and flowering nicely.

Thx that's reassuring, I was just worried bc the roots were popping out through the drainage hole a lil bit.
