There are many types of Hydroponic systems and not all plants can grow in each one. I find top feed with grow rocks or Lava rocks can grow most herb plants. Tomato plants work very good as well as a banana tree I have seen pictures of. GK saw it at a hydro show.

Cilantro like parsley top feed systems work. With top feed you can vary the drip amount different for each plant if you need to. Straw berries grow very well in hydro. Sometime you need to use a different medium, there are grow cubes, Higromite, coco peat, soil less mixtures like vermiculite & perlite and a few others I can't remember right now.

Do you understand how many different options there are to choose?


I hope that helped you a little.
