I am currently in the seedling stage of growing some white russian. I will be tranplanting in about 3 weeks (I predict), and Im just curious as to what size container I should transplant into. I have 5 gallon buckets on standby but I think that maybe to big. Do you have any advice? I'm pretty set on transplanting only one time so what do you think would be best? I've been told that my white russians will get about three feet tall.
