yeah it would, i have done one where i cut the bottom out of large pots 10-15 litre ones then placed them where i wanted them and added the soil then planted.

but you wouldnt have to cut the bottom out. but remember that you would have to have deep enough pots for them to get to you desired hight i read somewhere that the tap root of the MJ plant is about 1/3 of the overall height (someone correct me if i am wrong).
