Favorite veggies for media bed and DWC

I am close to finishing up my indoor aquaponics setup.  I am looking at 150 gallon fish tank and will start off with low stocking since I will have two chop and flip media beds and two DWC. I will double the media and DWC later.

I will try to control the temperatures to 70 to 80 degrees F and humidity to under 60% RH.  

I have a window AC unit, greenhouse heater and an air exchanger that will take air from my insulated only work shop (sort of a buffer to outside temperature extremes).

What are your recommendations for plants that stay under 18 inches or can be harvested at under 18 inches?  Are thee any special varieties that grow well under these conditions?  I would harvest plants when they are younger and tastier.

Are there any plants where I can just leave the roots planted and it will regrow?

Please mention varieties and if better in media bed or DWC.  

Thank you

Can't help very much with the best fish or plant selections. Sure is a nice looking set up though. Are those modified IBCs?

I do recommend getting the extension cords & plugs up off the ground. Spills happen.

I got the IBCs from a brewery that was moving. No water at this time.  I found a pallet rack so I made a double stack system.  Media beds on top and DWC on the bottom.  I hope to do leak checks this weekend.
