@mysteriousroad Hello I have some experience with hydroponic cultivation, at home, the way I learned, I think it is more practical, wooden tables are built according to space, and you make a drainage to place a small hose is lined with black plastic, I do not remember the caliber, then the substrate is placed which is the rice husk, or aliven, or coconut beard. There the seeds are placed in furrows, and are watered every day with nutrients, and always be aware of grooming the plant to keep them standing. I would like to show you a brochure.
