My girlfriend and I have recently attended a hydroponics seminar in which we got to make our own drip systems to take home. We have gone absolutely wild with the idea of hydroponics for ALL our green needs both recreational and culinary. Our two questions are whether you can grow any sort of bulb type plants (onions, garlic, etc) using a hydroponic system? And if you can grow poppies using a hydro system as well? Im guessing that you would have to use coco fiber to grow bulb type plants in a hydro setup? Thank you for any input you can provide..
