So, did you just turn the pots on their side? how did you get them to start vertical? I don't know how I could do this with my plant without spilling soil all over the place heh. I am growing Kali Mist which is suppose to get HUGE and I am worried about verticle space.
when you repot it, cut a almost equal size hole to your old pot on the side of your new pot, and stick it in sideways, that way you can still have easy access for water.. it worked fine for me..
Can you take an upclose picture of the pot? I mean the actual pot this time hehe and not the plant I just don't want to mess up doing something stupid hehe..
if you only have 2 plants, and sufficient lighting to completley cover them sideways, then definatley, they will all grow to huge colas ill post pics later ill be home soon
