How do I colonize different plant types?

[mac5732]

When I first played SE4, I learned the hard way on the colonizing asspect. Built colony shp in system, no problem colonizing, when I went out system, I tried colonizing, and it wouldn't let me, Loe and behold after much hair pulling and #*&^%$, It dawned on my feeble brain, I forgot to put people on it when going out system (blush, blush) had to go back load people then go back and instant colony, Oh well, I guess when you get my age the lst thing that goes is the brain waves.....

just some ideas mac
