This page is specifically for P4 Products using Planetary Interaction. Use PI Planets and type in a solar system to search for a system or couple systems that have all the planets you require (as listed below.) Avoid horribly overfarmed systems where possible. Getting it all in one system with a station that's not horribly overfarmed is ideal, but unlikely. Using two neighboring low traffic systems isn't too bad. Don't forget to check to make sure we own the POCOs! If you're not sure, ask. Hostile pocos will let you put stuff in them, but won't actually let you import or export.

I recommend one of these sites Alysii's PI Scheme or PI High-Tech Manufacturing Guide to see what you're looking for from each planet when you're actually evaluating planets for their suitability for your product.

There's some flexibility here, as you can choose to swap around your P0 to P1 planets, but this is a setup that makes sense.

This setup will need some modification. Wetware mainframes take more than 6 P2s to make. You probably can't do double production of these.
