I advise pneumatic tubes, they don't spill.

In my version, it first fills the fertilizer column, and then the other two colums, regardless of which side is used for input, so I use two crop matrons; one for fertilizer, and one for hydration cells. I am aiming for >21 growth so that my crops become immune to weeds, so no weed-ex for me. (I am well aware that such crops are dangerous to any crops with <21 growth. but immunity is worth it.)
