If you transplant and switch the photoperiod to 12/12 (if you haven't already) they won't get too big for you. Many strains virtually stop growing upward once the photoperiod is changed.

And the rule for pot size is a gallon for every month the plant is old.
jon.hatcher Reviewed by jon.hatcher on . pot size question Greetings, I am in week 5 of vegitive growth, my very healthy plants are currently in 2 gallon buckets and growing very fast, they are only 8" to 12" tall but have been LST'ed into bushes and are free to grow vertically now. My question is: Am I going to be OK in 2 gallon buckets if I put (can't remember the name ) those clay balls used in Hydroponics on top of the soil, so all the soil is used by the roots therefore utilizing the entire bucket space for roots. Or should I transplant Rating: 5
