I don't think cactus plants can make it in hydro. Some will grow better in dirt and some will grow better in hydro. I'm experimenting right now to see what plants will do okay in hydro. The cilantro I grew did not like being underwater all the time. It eventually drowned. The ones that had their tops about the water level did fine. The yellow onion I am growing right now does not like sitting in water. Lettuce does great in hydro.
