I’ve been doing some sort of experiment using hydroponic’s wick system to grow Roselle. Roselle is a tall plant and a species of hibiscus. I planted it once using soil awhile ago, they grew tall but once the flowers bloom it sudenly dried out never grew any new leaves and died. With this hyrdoponic Roselle i use 700=800 ppm AB mix nutrion since the beginning of vegetation. Unfortunately i can’t find any nutrion reference for roselle, maybe nobody grow it using hydroponic either. These are the pics from the beginning stage of Planting Roselle. Enjoy!
