i have got 10ltr pots , but i read in one of the treads here ,a guy commented about the pot being to big for the plant ? , my girls are in very small pots and i have these 5 ltr bio pots mad from cardboard or some shit . also i picked up a cheep summer fruits fertiliser not sure if i should use it , 8-8-8 , also i got a 58wtt 5ft flori tube with refuser , can i add this to my setup ? as a wall strip.

one of the girls is stunted , i think the fan might have loosened her from the soil , so i added some more , its looks ok know .
