Why not at sea grow plants and more it's easy? Not! Too cultivate plant you need many different data. That's why every grower in this line of business produce not in soil instead in mineral wool
to control the maximal. So it will happen in a cargo container with and without LED. Too reduce the cost at first I will try to develop a PI to control all the liquid later the whole greenhouse (container). It's a small step but it need to be done too collect data equal the location the sea with nothing around.
