The most important factor for plant growth without a soil medium is the balance of water and air. This Pafcal (soilless medium) developed by the Suntory Group after nearly ten years of research is a revolutionary invention, completely different from traditional soil. It can absorb water autonomously and evenly from bottom to top, maintaining a constant balance of water and air. Japanese patented Pafcal balances the ratio of air and water, providing a stable growth environment for plant roots. Balanced moisture, with each watering lasting about 7 days, eliminating the need for daily watering. The patented Pafcal evenly distributes water from top to bottom, preventing root rot. Formed in one piece without collapse, eliminating indoor green wall soil collapse and drainage clogging issues. The one-piece design is clean and easy to maintain. Stable plant growth, easy root development, and low maintenance. Inorganic and clean, free from pests and odors. Keeps the environment clean without water accumulation. No mosquito breeding. Half the weight of soil allows easy plant replacement according to seasons, large events, or store decor needs.
