Every kit contains all you need to your chosen herb. We use a recycled wine bottle to construct the body of the system, all edges are ground by hand so there’s no need to worry about sharp corners left over from cutting the bottle. Watering the kits could not be simpler just keep an eye on the water line (clearly visible) and top up when needed, every couple of weeks. Each kit contains enough organic hydroponic fluid for you to be able to grow your herbs for approximately two years. The kits also come with spare parts so that if your horticultural skills require a little honing there’s a second chance waiting.
