Hi Jake
Check out https://aquaponicsideasonline.com/ how-can-you-grow-aquaponics-tomatoes https://www.youtube.com/watch?v=Uuzzg65D6ZI. Aquaponics or hydrponics can succesfully grow leafy or vine plants in general, but is not as successful for root crops such as onions, garlic or carrots. Charlie Shultz of Ohio university has done a lot of work on this so you could start here with https://ohioaquaculture.org/pdf/Conference2015/AquaponicIssuesShultz.pdf if you wish to take the idea further. I have seen aquaponics units work very well in Oman, which is about as water scarce a setting as you will find.

John
