UPuper® grow medium is an inorganic inert substrate, which is made of natural rock Basalt at a high temperature of 1500°C. It does not carry any harmful organisms such as pathogenic bacteria and insect eggs. It is cleaner than other substrates and reduces the use of pesticides from the source. After testing, the product does not contain toxic and harmful heavy metals such as mercury, arsenic, lead, and cadmium, and there is no precipitation of any substances during use, which will not cause any harm to vegetable and cannabis cultivation, providing the healthy, safe and green vegetables and cannabis products.

At the same time, UPuper® is also making its own efforts to prevent the safety problems that growers and customers may encounter during planting. We provide each customer with PICC product quality liability insurance to protect your planting.
