Switched them from. The 4" pots to the 6" pots. Also did a 60/40 mix this time with the coco and perlite. Going to be just the two of them in this tent soon. Going to move them up to 8" pots next and then 3gal fabric. By the time I make the jump to the 3 gal, I'll make the choice on what one stays and goes, but rite now it might be a easy choice.
