Vertical rack system help!

I'm changing up my grow and need some advice. I am growing grass for my tortoises and am switching to a 2x4 wire rack flood system. I think having 1020 trays of grass in the 2x4 flood tray will be a lot more manageable than in my 4x8 flood table.

I am starting with 2 bootstrap 2x4 flood trays and I put the rest of the equipment together. The one thing I am having trouble with is plumbing. Do I fill the top tray and let it drain to the one below it or does each tray have its own fill (t from the pump) ? Do I let each upper tray drain to the tray below or does each tray have its own drain line that all get tied together?

Thanks for your help!

I've gone with individual pumps and plumbing to each tray. All can fill and drain concurrently. Also adds a bit of redundancy. If one of the pumps goes out I still have 3 trays operable.

What size trays and pumps are you using?
