if you want more with less water. https://youtu.be/VBspR2p0YYM a little example. Getting rid of rats you have to put traps at every growbed. Also how to get water is another problem. There is a solution if you got a water problem https://youtu.be/7-KxonnCXFY. Something like this can also be used in desert climates. But yes it uses power I don't know what costs more the power or the water.
Aquaponics is good for greens and such. Those, I am doing fine with right now. The rats are eating the fruit of my fruit trees (I have quite a few, forgot how many exactly but somewhere between 40 and 50.
I had aquaponics on my plan and have experimented with hydroponics. Aqua takes a bit of fiddling to get the ph right and I am not in a space where I can start a new project.
Thank you for your suggestions!
