Hi,
We just started our aquaponic for almost a month now. I understand that you are asking about hydroponic and I asked my husband if what kind of thing we have right now and hHe said it is aquaponic because we have the vegetable bed(hdyrdoponic) and the fish. The concept is very similar. Our set-up is a combination of two, the hydroponic and aquaculture. We only have one set-up right now and planning to make more grow beds.. We planted lettuce, pechay, peas,cabbage, onion, garlic and aloe. The plants are great and so healthy. It is very rewarding. We haven't harvest it yet because the leaves are yellow because of much nitrogen produce by the fish. So, right now, we are trying to add more veges to balance them. It is very exciting.... Though, you need to spent money to start it with but it is great.
