Question by ChrisWF: Plants I can use in an aquaponics system?
I saw a picture on the internet, where this pump sucks water out of a fish tank, sends it up to an area where plants grow and the water goes through a substrate or something where it filters out a lot of the bad content (nitrate and stuff plants love), then it delivers the remaining water back into the fish tank to repeat the cycle.

Now, if I remember correctly, can’t you drown a lot of plants? Or most plants?

I was thinking about maybe growing something neat like vegetables, and aiding the growth of the vegetables with my crayfish tank (who are very messy eaters).

For these types of aquaponic set ups, do you have to turn the water on and off? Or can the cycle keep going and you just don’t have to worry about your plants drowning?
If drowning is an issue, what plants do I use?

Thanks
Chris
