As we've all seen massive plants bursting tiny pots I don't think anyone told the plants.
I did a Lil very unscientific experiment a couple of years back were I put roughly the same size plants in small and large pots (standard pots not long toms) the results I got would suggest bigger the pot taller the plant (I'm no expert but I just figured the larger the root system the better anchored the taller it grew, to it's given height) I only did it with a flava, lueco and minor. I've grown a few minors on deep rose pots and personally I think they do better, I tried this as I always find minor to be the first out the bottom of the pot after repotting and I've read and been told about how they often grow in the dryer parts of sites. As I say I'm no expert just personal observations, all of my biggest plants are in massive pots (don't know the ltrs but they have handles and I struggle to move em! Lol)
I will add that without a doubt for me vft's thrive in long deep pots and after this winter I didn't lose 1 in a deep pot.
