Thanks for the words of encouragement! This has been stressing me out a bit over the last few months.

My current promising idea is a dutch style wicking hydro system. The reason being a fluid level sensor would be easy to install and interface with a holding tank of nutrient solution for automatic solution refill. Thinking it would be possible to seal the solution holding area, beneath the rich soil, better than any other hydro system. Also fewer powered pumps and moving parts with this system compared to other hydro setups. Power is VERY important.

Chemical solutions are a lot easier to carry on a sailboat than a ton of soil. Anyway, thoughts are welcome.

I appreciate your time and brain power towards this unique project.
