Ive run virtually ever regime, the only one I wouldn't run is 24/0 personally think they need sleep.
I cant imagine the autos would be any bigger if they had been on 18/6 or 20/4 the pots are only 6 litre or 6.5, they are a good size for that size pot either way I think. Ill do a pic update of them in a bit.
I just change stuff to suit really, plants get moved all over the shop, they all get a bit of sun and LED, except for winter when its just LED.
Ill have a read through of your diaries mate
