Fertilizer go into any of the four sides, Hydration cells at the top and Weed-ex at the bottom.

You can use pneumatic tubes though I would recommend using filters/transposers directly into the machine as it would prevent any bouncing from occuring.

Buildcraft pipes works just as well, but since it only has room for 3 Weed-ex and 3 Hydration cells you would probably end up with a lot of them on the floor. That's fine if you have an obsidian pipe with an engine to pick everything up, but it's still preffered to use filters/transposers.
