Not sure I completely understand your question. You supply your planter with seeds, regular plain old vanilla MC seeds. To get your harvester to supply your planter with more vanilla seeds, use a diamond pipe below the harvester, then supply gold/stone transport pipes to the bottom of your planter. then connect more gold/stone pipes to another side of the diamond pipe and lead it to a chest. Then use your diamond pipe's GUI to select which colours the planter's pipe leads to and place a seed into the GUI's correct colour, and then do the same with your chest and use wheat on that colour.

Hope this makes sense. If need be I will get a screenshot or make a video for you.
