I have recently started playing with hydroponics in my balcony. I had success with jalapeños in a simple bubbler setup. Also tomatoes worked great in an ebb and flow system. Basil works, coriander is a bit iffy, dill does not grow. How do you know what will work and which plants need what kind of nutrients?
I’ve had basil in DWC with bubbler and couldn’t eat or give away enough of it, it just grew so much (and was so potent). The rest match your experience.
As for nutrients, I do a trial run in a separate system and try to watch how the plant reacts. I’m amateur anyway, so losing a plant is expected. Question is just how much harvest I can get before then. With huge or automated systems you probably need precision and data, for my 10-30 plants I can just look at them :P
Other varieties that have worked well for me in DWC w/ bubbler: cucumber, flowering flax, every kind of lettuce, bok choi, cherry tomatoes, oregano, marjoram, thyme, shiso/red mint, microgreens, radish.
I’ve heard rumor of strawberries, wild strawberries, aubergine, even pumpkins to be good in DWC, and of course almost all types of chili.
I haven’t had any luck yet with lemongrass, rosemary, as you with coriander, fennel, strawberries, wild strawberries, among others.
Did a test run with flowering plants that had growth but no flowers, so that’s promising for a bit of fiddling with nutrients and lighting schedules.
