I started all my seedlings in 4" pots when they were about 4" our taller i moved them ro 6" pots. This seemed to let them explode in growth. Must of my plants raced to around 8" after they got their bigger homes. However, for a good while now there had been no more growth, I've looked on here and seen much bigger plants than mine in 6" pots. I decided to try and go ahead and move one of my 8" bhuts to a 5 gallon bucket to see if he takes off again. When i removed it from the 6" pot i noticed it had a MASSIVE root system. Literally circling the pot was a wall of roots that made it slightly difficult to shake out the old soil. So my question is: an i doing something right? I've read here that you want a good root system, but is it ok if my plants are needing to be re-potted at this size? Thanks again everyone, i wouldn't have made it this far without your expertise.
