Plant size is dependent on pot size and the amount of room the roots have to grow.Of course this is just one factor in determining growth and size.I do a 2 and 1/2 to 3 month veg with my girls so I try to use 5 gallon pots when possible and I have been thinking about increasing pot size in the near future (well bucket size to be precise as Im gonna get wet here in a couple of months).Good luck with your grow and congrats on getting a handle on the pest problem.Take care,be well,and most of all be safe.
