I have 5 ea. of 5 gal. pots, but only have 2 3 gal. pots I want to just go from typical red party cups and transplant them into the 5 gal. pots with fox farm OF soil and I will use fox farm nutes with molasses. Is there any difference between transferring from a red cup to 3 gal. pots then to 5 gal. pots? Also how big can a plant get in a pot?
