Saipan Teacher Uses 6P7 Aeroponic Tower System For Hydroponics Teaching.Frank is a primary school nature course teacher on Saipan Island. Despite the lack of land resources on the island, Frank still tries many ways to let the children experience the fun of planting. He usually takes the children on many natural planting courses, thus generating their love for life and reverence for nature. By chance, Frank learned about hydroponic farming and became very interested in it. He researched the products of many manufacturers on the Internet and finally chose our 6P7 Aeroponic Tower System after comprehensive consideration of quality, price and after-sales.
