Here is the picture Frogboy. Approval is the limiting factor on pop size. Merc ships help a lot.

Only takes 1 colony ship with 2 colony modules. Drops off 5 pop per trip. Boosts output, but not game breaking. FYI Publius of NV. Was playing with Theocracy Gov. Was role playing that they were taking a pilgrimage to the holy city, and population was droping because they were going back home.
No mods. Intrigue and Crusades installed. The population cap only applies to natural growth, not people shipped in on colonizers. The population slowly decreases by 0.1 per turn, but that is not a big deal since the population growth on the planets feeding it are both 1.5 per turn.
Got a planet up to 81 population today. Used colonizers to keep dropping people off. Over 100 raw production. Over 500 research a turn. The planets I was pulling the people from had hospitals so they were able to keep up. Was fun so I thought I would share.
