if you feal the need to move your plants go for it, but putting them in a pot means you have to water them, which will eventually leave a trail and make it necesarry for you to move them. i prefer to transplant into well ammended soil, the tap root will reach the water table in a month and you will never need to water it unless it gets very dry, i have had to transplant 4 foot plants before and never have lost one, the hardest part is carrying the heavy dirtball in the humid summer. most people could walk within 20 feet of my plot and never see it, a few growbags (kinda pricy by the way) look pretty obvious.
